Revitalizing the skin: Exploring the role of barrier repair moisturizers. J Cosmet Dermatol 2024; 23:1533-1540. [PMID: 38214440 DOI: 10.1111/jocd.16171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 11/30/2023] [Accepted: 12/28/2023] [Indexed: 01/13/2024]
Abstract
BACKGROUND Moisturizers are designed to maintain skin health and treat dermatological conditions associated with impaired skin barrier function. However, differences in their composition account for the differences in their effect. AIMS This narrative review aims to discuss the role of barrier repair moisturizers, highlight the role of different components in a moisturizer and their role in impaired skin conditions (e.g., dry, itchy, inflamed, sensitive skin, atopic eczema), and thereby empower dermatologists and pediatricians in selecting the right moisturizer. METHODS PubMed, Embase, and Scopus electronic databases were searched from January 2000 to June 2023 for publications on skin barrier repair and use of barrier repair moisturizers for the treatment of dry, itchy, inflamed, sensitive skin, or atopic eczema. Studies conducted in humans, published in English for which full texts were freely available were included. RESULTS The structure and composition of lipid lamellae within the stratum corneum play an important role in maintaining an effective skin barrier and protecting the body from various external assaults. Endocannabinoid mediators play an active role in maintaining skin barrier function. Moisturizers containing physiological lipids and functional ingredients (e.g., endocannabinoids such as palmitoylethanolamide [PEA]) and based on the principles of biomimic technology are demonstrated to be beneficial for the management of conditions associated with a disrupted skin barrier. CONCLUSIONS Moisturizer based on the innovative biomimic formulation has good cosmetic efficacy and is generally well tolerated, and the addition of PEA might represent a new generation of compounds that may be beneficial for long-term management of impaired skin conditions.

Efficacy of ceramides and niacinamide-containing moisturizer versus hydrophilic cream in combination with topical anti-acne treatment in mild to moderate acne vulgaris: A split face, double-blinded, randomized controlled trial. J Cosmet Dermatol 2024; 23:1758-1765. [PMID: 38299457 DOI: 10.1111/jocd.16212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 01/16/2024] [Accepted: 01/23/2024] [Indexed: 02/02/2024]
Abstract
INTRODUCTION Topical therapy is the mainstay treatment of acne, and topical retinoids such as tretinoin, tazarotene, and adapalene are recommended as the first-line therapy for mild to moderate acne. However, the cutaneous irritations may occur, and the dermocosmetics are recommended to prevent side effects of anti-acne drugs and adhere to treatment. Thus, this study aims to compare the efficacy and tolerability of ceramides and niacinamide-containing moisturizer (CCM) versus hydrophilic cream in combination with topical anti-acne treatment in mild to moderate acne vulgaris. METHODS This was an 8-week, randomized, double-blinded, split face study in 40 patients assigned for topical anti-acne medications (5% benzoyl peroxide and 0.1% adapalene gel), then randomly applied CCM or hydrophilic cream. All patients were followed at week 0, 2, 4, and 8 for acne improvement, adverse reactions, biometric, and biophysical evaluation. RESULTS CCM could significantly improve the non-inflammatory, inflammatory, and total acne lesions compared with hydrophilic cream after week 8 of treatment. Interestingly, there was an improvement of global worst score, hemoglobin index, melanin index, TEWL, skin hydration, sebum production, and skin surface pH, with no statistically significant differences between the two treatments. No serious side effects from clinical application of CCM and hydrophilic cream in mild to moderate acne vulgaris patients. CONCLUSION Ceramide and niacinamide-containing moisturizer in combination with anti-acne medication can significantly improve acne lesions and decrease cutaneous irritations toward a satisfactory treatment outcome of mild to moderate acne vulgaris.

Abstract
Petrolatum, also known as petroleum jelly, is a widely used topical agent, with a variety of uses in dermatology. Despite its popularity, many myths surround this ubiquitous dermatologic staple. This review details the history of petrolatum and how it is manufactured as well as how its biologic properties make it a great moisturizer. Additionally, data on its potential for flammability, allergenicity, and comedogenicity are detailed, dispelling misconceptions about petrolatum use around oxygen and as a cause of acne. The uses and benefits of petrolatum in dermatology are wide-ranging-a patch test instrument, a vehicle for medicated ointments, and a wound care essential. Given its ubiquitous presence, it is important for dermatologists to understand the history, safety profile, and myths surrounding this humble skincare staple.

[PMID: 38131920 PMCID: PMC10742648 DOI: 10.3390/gels9120934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 11/06/2023] [Accepted: 11/15/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND The aim of this study was to evaluate the moisturizing efficacy of quince fruit, used in folk medicine. For this purpose, the phytoconstituents of Cydonia oblonga fruit extract, like phenolics and flavonoids, were determined. A stable cosmetic emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and subjected to in vivo evaluation compared with a control. MATERIALS AND METHODS Cydonia oblonga fresh fruit extract was evaluated for tyrosinase activity and phenolic and flavonoid content. A stable emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and tested in a skin irritation test. After this, in vivo tests of erythema, moisture, sebum, and skin elasticity were conducted. The in vivo evaluation was a randomized and single-blind study. Thirteen healthy female volunteers were selected for a three-month study period. RESULTS Cydonia oblonga fruit extract showed good phenolic and flavonoid content, which was associated with its good antioxidant and tyrosinase-inhibiting activity. Cydonia oblonga containing the emulgel showed a reduction in sebum and erythema, while the elasticity and moisture content showed increments in their levels after the three-month application of the formulation. The fruit contains chlorogenic acid and many sugars, which might account for its anti-inflammatory and sebum reduction effects; it is also capable of enhancing the skin's hydration level and decreasing skin sagging by enhancing its elasticity. CONCLUSION The emulgel loaded with Cydonia oblonga fresh fruit extract is verified regarding its folklore status as a moisturizing agent that enhances the facial skin cells' resilience potential.

A novel hydrogel-based moisturizing cream composed of hyaluronic acid for patients with xerosis: An intraindividual comparative analysis. Skin Res Technol 2023; 29:e13499. [PMID: 38009036 PMCID: PMC10616540 DOI: 10.1111/srt.13499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 10/05/2023] [Indexed: 11/28/2023]
Abstract
BACKGROUND Hyaluronic acid (HA) is mainly used to treat xerosis. It also exerts wound-healing, moisturizing, and antiaging effects. Although HA is considered an effective and safe ingredient in cosmetics, there is a constant demand for a more money-saving and effective formulation. This study aimed to evaluate the safety and efficacy of a novel hydrogel-based moisturizer containing HA cross-linked with silicone polymers, produced solely through irradiation without the use of cross-linking agents. MATERIALS AND METHODS A safety study enrolled 30 participants with healthy skin to perform patch and photopatch tests while recording adverse events. For the efficacy study, 30 participants with xerosis were compared before and after using the novel hydrogel, evaluating the cutaneous barrier function, xerosis severity scale (XSS) score, participant's satisfaction, and Investigator's Global Assessment (IGA). Furthermore, the efficacy of the novel hydrogel-based moisturizer was evaluated by comparing it with a conventional moisturizer, Physiogel, in another 30 participants with xerosis. RESULTS In the safety study, no serious adverse events were observed. In the efficacy study before and after use, skin hydration and skin surface lipid increased (p < 0.05) whereas the XSS scores decreased (p < 0.05) with time. In the comparative efficacy study with Physiogel, skin hydration increased whereas the XSS scores decreased (p < 0.05) over time in both groups. Furthermore, IGA improved in 100% of participants in both groups. Also, 100% and 93% of participants were satisfied with the novel hydrogel-based moisturizer and Physiogel, respectively. CONCLUSIONS The novel hydrogel-based moisturizer proved to be safe and effective for xerosis, showing comparable results to the conventional moisturizer.

Efficacy of anti-sebum moisturizing cream containing 2% l-carnitine and 5% epigallocatechin gallate in seborrhea: A randomized clinical trial. J Cosmet Dermatol 2023; 22:3058-3064. [PMID: 37194909 DOI: 10.1111/jocd.15816] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 04/30/2023] [Accepted: 05/03/2023] [Indexed: 05/18/2023]
Abstract
BACKGROUND Seborrhea leads to facial greasiness and unpleasant feeling. People with seborrhea also have trouble with selecting moisturizers. l-Carnitine and epigallocatechin gallate (EGCG) are reported anti-sebum properties. However, neither efficacy comparison nor the combination effect of the two topical anti-sebum agents was studied. Moisturizing cream with these agents is supposed to provide skin with an optimal water-oil balance. AIMS To compare the efficacy of moisturizer containing 2% l-carnitine or 5% EGCG alone on sebum controlling, and the synergistic effect of these two agents. METHODS Three study creams were formulated by adding three kinds of anti-sebum agents which were 2% l-carnitine, 5% EGCG, and 2% l-carnitine plus 5% EGCG in moisturizing cream base of dimethicone and glycerin. A randomized clinical trial was conducted. Ninety subjects, divided into three groups, applied the cream for 4 weeks. Sebum level, skin capacitance, and transepidermal water loss (TEWL) were evaluated at Weeks 0, 1, 2, and 4. Life qualities and subjective outcomes were assessed before and after treatment. RESULTS The mean sebum reduction from baseline was statistically significant in all treatment groups (p < 0.01). The median time to oil control was longer in l-carnitine group. The combine group had significantly greater anti-sebum efficacy than l-carnitine group (p = 0.009). All three groups had significant improvement of other objective parameters and subjective outcomes. CONCLUSIONS The anti-sebum moisturizing cream exhibited beneficial effect on the sebum reduction with improve skin hydration in people with seborrhea and made users satisfied. The EGCG group and the combine group show the greater anti-sebum effect than the l-carnitine group.

Abstract
The skin microbiota barrier participates in skin barrier function in addition to the physical, chemical, and immunological protective barriers, and is affected by environmental aggressors and skincare regimens. To better understand the exact effects of real-life environmental conditions on the skin and determine the protective methods, this study investigates the effects of three topical cosmetic moisturizers (water gel moisturizers with/without yeast extract (Moisturizers K and C) and a thick-emulsion cream moisturizer (Moisturizer L)) on clinical and skin microbiome endpoints in the presence of environmental aggressors during an 8-week, randomized controlled, triple-blind clinical trial with 110 participants, and molecular- as well as biomarker-level endpoints on ex vivo skin explants after exposure to simulate urban environmental conditions. The results show that all moisturizers are well-tolerated and improve skin barrier function and surface moisture content from the baseline, and the improvement is maintained at the last analysis point (3 days after trial completion). Compared with the untreated control areas (samples taken from the upper chest), treatment with Moisturizer K prevented a reduction in bacterial and fungal richness, and increased the change ratio of the relative abundance of commensal bacteria, such as Staphylococcus epidermidis and Ralstonia, at the treated sites (samples taken from the forehead). Moreover, Moisturizer K-treated ex vivo skin explants had higher levels of caspase 14 (a marker of skin barrier function), collagen I, and elastin (structure components), and lower levels of aryl hydrocarbon receptor (AHR; activated by air pollutants) and interleukin-6 (IL-6) than those in explants treated with other moisturizers and in the untreated areas of the skin. These results suggest that a skin postbiotic moisturizer with yeast extract supports the regulation of the skin's microbiome balance and may provide a holistic barrier (involving skin microbiome, physical, chemical, and immune barriers) to protect the skin against environmental aggressors.

Abstract
Agarobiose (AB; d-galactose-β-1,4-AHG), produced by one-step acid hydrolysis of agarose of red seaweed, is considered a promising cosmetic ingredient due to its skin-moisturizing activity. In this study, the use of AB as a cosmetic ingredient was found to be hampered due to its instability at high temperature and alkaline pH. Therefore, to increase the chemical stability of AB, we devised a novel process to synthesize ethyl-agarobioside (ethyl-AB) from the acid-catalyzed alcoholysis of agarose. This process mimics the generation of ethyl α-glucoside and glyceryl α-glucoside by alcoholysis in the presence of ethanol and glycerol during the traditional Japanese sake-brewing process. Ethyl-AB also showed in vitro skin-moisturizing activity similar to that of AB, but showed higher thermal and pH stability than AB. This is the first report of ethyl-AB, a novel compound produced from red seaweed, as a functional cosmetic ingredient with high chemical stability.

Abstract
The demand for non-hormonal therapies for vulvovaginal atrophy (VVA) is increasing due to an increasing number of patients surviving long term post cancer diagnosis, as well as increased public knowledge of the symptoms of menopause and availability of non-hormonal therapies. Treatment options are wide-ranging and encompass different formulations and methods of application. This review summarizes the key characteristics of the main forms of these therapies, as well as considering the current evidence for each of them and where future clinical studies should be directed. Care for VVA may be in primary care, or under gynecology or oncology. Further research requirements include the need for long-term data as well larger randomized controlled trials into alternatives where vaginal estrogen cannot be used as first-line treatment. Widespread education of health-care providers and patients on VVA and the impact on quality of life is urgently needed, as well as increased use of non-hormonal methods in routine clinical practice.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the general population. Skin barrier dysfunction is the central abnormality leading to AD. The cause of skin barrier dysfunction is complex and rooted in genetic mutations, interactions between the immune pathway activation and epithelial cells, altered host defense mechanisms, as well as environmental influences that cause epithelial cell activation and release of alarmins (such as thymic stromal lymphopoietin) which can activate the type 2 immune pathway, including generation of IL-4 and IL-13, which induces defects in the skin barrier and increased allergic inflammation. These inflammatory pathways are further influenced by environmental factors including the microbiome (especially Staphylococcus aureus), air pollution, stress, and other factors. As such, AD is a syndrome involving multiple phenotypes, all of which have in common skin barrier dysfunction as a key contributing factor. Understanding mechanisms leading to skin barrier dysfunction in AD is pointing to the development of new topical and systemic treatments in AD that helps keep skin borders secure and effectively treat the disease.

Abstract
BACKGROUND Prolonged face mask usage, a daily practice for the public due to the COVID-19 pandemic, creates high levels of humidity underneath the mask, which may cause unexpected skin concerns. OBJECTIVE To investigate the impact of repeated mask usage on the face by comparing skin properties inside and outside of the mask-covered areas. METHODS A double-blinded, randomized, split-face clinical study was conducted with 21 healthy female participants who wore face masks at least 6 h every day for 1 week, with one side of their face treated with a moisturizer three times daily. On day 8, after 5 h of wearing the mask, skin properties (sebum, hydration, and trans-epidermal water loss [TEWL]) were evaluated at 15, 60, and 120 min post-mask removal, followed by barrier disruption and recovery assessment. RESULTS Mask usage weakened stratum corneum (SC) on facial skin compared to uncovered areas, including reduced SC hydration (p < 0.02 at 15 min) and increased TEWL in response to tape stripping challenge (p < 0.03 after stripping). In addition, sebum production also increased after mask removal (p < 0.01 at 15 min). Notably, a daily moisturizer mitigated these effects by increasing SC hydration (p < 0.001) and improving SC resilience against barrier disruption. CONCLUSION Daily prolonged usage of a facial mask, essential due to the COVID-19 situation, generated a high-humidity microenvironment and led to compromised SC, which was revealed by a barrier challenge technique. Moreover, proper facial moisturization may help to maintain skin homeostasis and prevent the barrier impairment caused by repeated mask usage.

Abstract
BACKGROUND Hyaluronic acid (HA) is among the most effective and safe ingredients frequently used in cosmetics. However, a more economical and efficient formulation is still required. OBJECTIVE We sought to assess the safety and efficacy of a novel hydrogel manufactured only by irradiation containing cross-linked HA and polyethylene glycol polymers with addition of polysiloxane. METHODS The study included 30 people with normal skin and 30 patients with xerosis. In the normal skin group, to evaluate the safety, a patch test and a photopatch test were performed, and patients' discomfort was investigated. In those with xerosis, to assess the efficacy, a skin barrier function test was performed at baseline and at 2, 4, and 8 weeks after the application of the novel hydrogel. Additionally, the xerosis severity scale (XSS), patient satisfaction, Investigator's Global Assessment (IGA), and adverse responses were evaluated. RESULTS In the safety study, there was no significant discomfort in the experimental group compared with the control group. In the efficacy study, at 2, 4, and 8 weeks after the application of the novel hydrogel, the mean value of skin hydration and sebum content increased and the mean value of XSS decreased with time in the experimental group, and a difference was observed when compared with the control group. IGA showed improvement in 97%, 77%, and 80% at each visit and the proportions of satisfied patients were 90%, 87%, and 90%, respectively. CONCLUSIONS The novel HA-based hydrogel tested herein could be a safe and effective therapeutic remedy for xerosis.

Abstract
Atopic dermatitis (AD) is a chronic disease in which epidermal barrier disruption triggers Th2-mediated eruption of eczematous lesions. Topical emollients are a cornerstone of chronic management. This study evaluated efficacy of two plant-derived oil derivatives, isosorbide di-(linoleate/oleate) (IDL) and isosorbide dicaprylate (IDC), using AD-like tissue culture models. Treatment of reconstituted human epidermis with cytokine cocktail (IL-4 + IL-13 + TNF-α + IL-31) compromised the epidermal barrier, but this was prevented by co-treatment with IDL and IDC. Cytokine stimulation also dysregulated expression of keratinocyte (KC) differentiation genes whereas treatment with IDC or IDL + IDC up-regulated genes associated with early (but not late) KC differentiation. Although neither IDL nor IDC inhibited Th2 cytokine responses, both compounds repressed TNF-α-induced genes and IDL + IDC led to synergistic down-regulation of inflammatory (IL1B, ITGA5) and neurogenic pruritus (TRPA1) mediators. Treatment of cytokine-stimulated skin explants with IDC decreased lactate dehydrogenase (LDH) secretion by more than 50% (more than observed with cyclosporine) and in vitro LDH activity was inhibited by IDL and IDC. These results demonstrate anti-inflammatory mechanisms of isosorbide fatty acid diesters in AD-like skin models. Our findings highlight the multifunctional potential of plant oil derivatives as topical ingredients and support studies of IDL and IDC as therapeutic candidates.

Abstract
BACKGROUND Several studies have evaluated prophylactic emollients as a preventive strategy against atopic dermatitis (AD) and food allergy (FA). We aimed to synthesize the evidence on efficacy and safety of prophylactic emollients started during the first 6 weeks of infancy for prevention of AD and FA. METHODS MEDLINE, Embase, CINAHL, BIOSIS, and the Cochrane Library databases were searched systematically for randomized controlled trials published between January 2000 and July 2020, which assessed the effects of prophylactic emollients initiated within the first 6 weeks of life on the development of AD within 24 months of age, compared to no treatment. Risk of bias and certainty of evidence were assessed using the Cochrane Collaboration's tool and GRADE process, respectively. RESULTS Of the 1486 articles identified, 10 studies fulfilled inclusion criteria. In infants given emollients, there was no significant reduction on the development of AD (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.64, 1.10) compared to the control group. However, there was significant benefit of prophylactic emollients (RR 0.75, 95% CI 0.62-1.11) in the high-risk population (n = 8 studies). There was also significant benefit (RR 0.59, 95% CI 0.43, 0.81) in studies (n = 6) where emollients were used continuously to the point of AD assessment; but not when treatment was ceased for an interval before AD assessment. There were no protective effects on FA found. CONCLUSION The prophylactic application of emollients initiated in early infancy may prevent AD, especially in high-risk populations and when used continuously. We hypothesize that emollients may delay rather than prevent AD.

Abstract
BACKGROUND Dry, itchy skin can lower quality of life (QoL) and aggravate skin diseases. Moisturizing skin care products can have beneficial effects on dry skin. However, the role of a daily skin care routine is understudied. OBJECTIVE To understand how daily skin care with a mild cleanser and moisturizer impacts skin health and patients' QoL, in dry skin population. METHODS A randomized, investigator-blinded study of 52 participants with moderate to severe dry skin. The treatment group (n = 39) used mild cleanser and moisturizer twice daily for two weeks whereas the control group (n = 13) used mild cleanser without moisturizer. Total Clinical Score (TCS; erythema, scale and fissures), Visual Dryness Score (VDS) and subjective itch-related quality of life (ItchyQoL) were collected. RESULTS The treatment group showed significantly more improvement in TCS and VDS compared to the control group after two weeks. Among the three components of the ItchyQoL (symptoms, functioning, and emotions), symptom showed significantly greater improvement in the treatment compared to the control group. Over 80% of participants in the treatment group agreed that the regimen led to decrease in dryness/pruritus and improved skin texture. CONCLUSIONS A consistent skin care regimen should be an integral component of management of dry skin.

Pre-Clinical Evaluation of Proprietary Lutein, Zeaxanthin, and Rosemary Formulation for Its Dermal Protective Activity in Male Swiss Albino Mice. Prev Nutr Food Sci 2021; 26:425-433. [PMID: 35047439 PMCID: PMC8747954 DOI: 10.3746/pnf.2021.26.4.425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 08/23/2021] [Accepted: 09/01/2021] [Indexed: 11/06/2022] Open
Abstract
This study aimed to evaluate the efficacy of the proprietary lutein, zeaxanthin, and rosemary formulation for its dermal protection against ultraviolet (UV) irradiated skin dehydration. A total of 48 male Swiss albino mice of 8∼12 weeks of age were divided into eight groups of 6 mice: mice in group 1 (G1) were considered the normal control, without treatment and without skin shaving; mice in G2 had their skins were shaved, but did not receive treatment; mice in G3 were the pathological control; mice in G4 were treated as standard (hyaluronic acid); mice in G5∼G8 were treated with low and high doses of 2 different test substances, respectively. Mice were anaesthetized and then depilatory was applied on the dorsal skin area (2 cm×2 cm) on alternate days, then UV/blue light irradiation was carried out for 15 min for 6 weeks. Collagen type 1 gene expression was determined via densitometric analysis, skin elasticity was assessed, and stratum corneum water contents were measured using a cutometer and corneometer. Skin hydration was assessed through transepidermal water loss, and several serum biochemical parameters (collagenase, hydroxyproline, hyaluronic acid, and ceramide levels) were determined to assess the skin moisturizing activity of the product. Images for assessing photoaging were considered between different groups on day 42. All these subjective parameters reached statistical significance (P<0.05) in groups treated with the proprietary lutein and rosemary formulation compared with the placebo-treated group. In conclusion, the proprietary lutein, zeaxanthin, and rosemary formulation showed better protection of skin subjected to UV irradiated skin dehydration.

Efficacy of Dendrobium candidum polysaccharide extract as a moisturizer. J Cosmet Dermatol 2021; 21:3117-3126. [PMID: 34841665 DOI: 10.1111/jocd.14586] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 10/20/2021] [Indexed: 12/25/2022]
Abstract
INTRODUCTION This study investigated the role of natural polymers as moisturizers with low toxicity and biodegradability in the cosmetic and pharmaceutical industries. We isolated a polysaccharide extract from Dendrobium candidum (D. candidum) and determined its efficacy in skin hydration when used as an active cosmetic ingredient. METHODS The molecular weight distribution of D. candidum polysaccharides was analyzed via gel permeation chromatography (GPC). We performed real-time reverse transcription PCR (RT-PCR) and western blotting assays to investigate the physiological mechanism of the polysaccharides extracted from D. candidum (PDC). Based on in vitro data, the efficacy of PDC in improving skin condition was tested on the face of 21 volunteers. RESULTS The expression of filaggrin (FLG), caspase-14, and bleomycin hydrolase, which are the major components contributing to skin hydration, was significantly increased in the PDC-treated group. Further, the PDC upregulated the mRNA expression of occludin and claudin-1, which play a key role in epidermal barrier function. In addition, a topical application of PDC markedly increased skin hydration and improved trans-epidermal water loss (TEWL) and skin elasticity after 2 weeks. CONCLUSIONS It is the first study reporting the efficacy of PDC-mediated FLG mechanism associated with positive skin hydration. PDC can be used as an active ingredient in moisturizers. Long-term application of PDC-based moisturizers may result in significant improvement in elasticity and barrier function.

Optimal application method of a moisturizer on the basis of skin physiological functions. J Cosmet Dermatol 2021; 21:3095-3101. [PMID: 34743412 PMCID: PMC9543289 DOI: 10.1111/jocd.14560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 09/13/2021] [Accepted: 09/28/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Clinical studies have clarified the usefulness of moisturizers for dry skin diseases. However, few reports exist on the appropriate application of moisturizers with respect to the skin physiological functions. AIMS To clarify the optimal moisturizer application method on the basis of skin physiological functions. METHODS This study investigated the appropriate time, dose, and frequency of moisturizer application from the perspective of skin physiology. In healthy subjects, the stratum corneum water content (SCW) was compared between different moisturizer application times (immediately [≤5 min] and 90 min after bathing), doses (0.5, 1.0, and 2.0 mg/cm2 ), and frequencies (once and twice daily). Thereafter, patients with dry skin were treated with the moisturizer once or twice daily for 8 weeks at the time, and application dose was determined to be optimal for the healthy subjects; the moisturizing effect was evaluated based on the SCW, trypsin activity, and desmoglein 1 localization score in the stratum corneum. RESULTS In healthy subjects, compared to at control sites, the SCW was significantly higher at sites treated with the moisturizer immediately after bathing, with 1.0 and 2.0 mg/cm2 of the moisturizer, and with once- and twice-daily applications. In patients with dry skin, the SCW was significantly higher compared to control sites and the desmoglein 1 localization score was significantly lower after 8 weeks only when the moisturizer was applied twice daily. CONCLUSIONS Moisturizer application of ≥1.0 mg/cm2 twice daily (immediately after bathing at night and in the morning) had a moisturizing effect, as verified from the skin physiological functions.

Comparison of Therapeutic Effects of Topical Calcineurin Inhibitor and Moisturizing Cream on Pruritic External Auditory Canal. J Clin Med 2021; 10:jcm10194313. [PMID: 34640333 PMCID: PMC8509200 DOI: 10.3390/jcm10194313] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/10/2021] [Accepted: 09/10/2021] [Indexed: 12/02/2022] Open
Abstract
Although pruritic external auditory canal (PEAC) is a relatively common symptom, particularly in the geriatric population, its pathophysiology and appropriate treatment remain to be elucidated. We compared the therapeutic efficacy of pimecrolimus, a topical calcineurin inhibitor (CI), and a moisturizing cream (MC) in patients with PEAC. Thirty-nine patients (73 ears) were prospectively enrolled and treated topically twice daily with the CI (n = 20, 39 ears) or the MC (n = 19, 34 ears) for two weeks. The change in itching sensation was evaluated subjectively using a self-questionnaire at immediately, one month, and two months after self-application, and objectively by changes in erythema grading. Although topical treatment with the CI resulted in a more rapid improvement than treatment with the MC in patients with PEAC, the final outcomes did not differ between the groups. Furthermore, similar improvements in erythema scores were noted. The results of this study suggest that the MC, which rejuvenates the normal physiological status of the ear canal skin, may greatly benefit those elderly patients more susceptible to PEAC, without any concerns about adverse events and underlying comorbidities. Expanding upon the understanding of the role of moisturizers in the treatment of pruritic ears merits attention, as this knowledge provides a good example of the clinical guidelines for the management of PEAC.

Clinical study on the effects of the applied volume of moisturizer in patients with asteatosis. J Dermatol 2021; 49:75-85. [PMID: 34545613 PMCID: PMC9292982 DOI: 10.1111/1346-8138.16160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 09/02/2021] [Accepted: 09/04/2021] [Indexed: 11/30/2022]
Abstract
Asteatosis is characterized by decreased stratum corneum water content, and the basic treatment is to keep the skin moisturized. Poor application of moisturizers by patients may reduce treatment efficiency, so it is important to continue application as instructed by dermatologists. Application instructions based on the finger‐tip unit are useful for patients, but there is no clear evidence of its efficacy. We investigated the effects of the volume of the moisturizer (Hirudoid® Cream 0.3%) administrated with 1/3 finger‐tip unit and 1 finger‐tip unit equivalent doses per target lower leg of patients with asteatosis (twice daily, 28 days) on the overall dry skin scores, itch numerical rating scale scores, and skin physiological parameters (stratum corneum water content, transepidermal water loss, and skin pH). Sixty patients were randomized with a 1:1 allocation ratio into two groups: the 1/3 finger‐tip unit and 1 finger‐tip unit equivalent dose groups. The results showed that 43.3% of the patients in the 1 finger‐tip unit equivalent dose group, compared with 13.3% in the 1/3 finger‐tip unit equivalent dose group, presented zero overall dry skin scores 1 week later. As the overall dry skin scores improved, the stratum corneum water content also increased. In patients with moderate itching, the itch numerical rating scale scores of the 1 finger‐tip unit equivalent dose group decreased significantly compared with those of the 1/3 finger‐tip unit equivalent dose group. The results suggested that the application of 1 finger‐tip unit equivalent dose of the moisturizer twice daily in clinical practice could induce remission more quickly. With the 1/3 finger‐tip unit equivalent dose, prolonged treatment may be necessary to achieve the desired effect; therefore, application adherence is strictly required. In conclusion, the application of a 1 finger‐tip unit equivalent dose would be quite reasonable in clinical practice.

Abstract
BACKGROUND Topical moisturizer is recommended for atopic dermatitis. AIMS The aim of the study was to investigate the knowledge gap regarding the efficacy of moisturizer in young patients. METHODS A systematic review and meta-analysis were conducted on randomised controlled trials comparing participant's ≤15 years with atopic dermatitis, receiving either topical moisturizer or no moisturizer treatment. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. RESULTS Six trials were included (intervention n= 436; control n= 312). Moisturizer use extended time to flare by 13.52 days (95% confidence interval 0.05-26.99, I2 88%). Greater reduction in risk of relapse was observed during the first month of latency (pooled risk ratio 0.47, 95% confidence interval 0.31-0.72, I2 28%) compared to the second and third months (pooled risk ratio 0.65, 95% confidence interval 0.47-0.91, I2 35% and pooled risk ratio 0.63, 95% confidence interval 0.47-0.83, I2 33%, respectively).Treated patients were 2.68 times more likely to experience a three-six months remission (95% confidence interval1.18-6.09, I2 56%). Moisturizer minimally improved disease severity and quality of life. LIMITATIONS There is a dire need to conduct randomised controlled trialswith more robust and standardised designs. CONCLUSION Moisturizer benefits young patients with atopic dermatitis. However, more research is needed to better estimate its efficacy.

Abstract
The increasing incidence of frontal fibrosing alopecia (FFA) suggests that environmental factors may be related to the pathogenesis. Recent studies reported potential association between the use of facial care products and FFA. The aim of this study was to investigate the possible association between the use of facial care products and FFA in Asian females. A total of 250 females (50 FFA patients, 100 pattern hair loss [PHL] patients, and 100 normal controls) were recruited and completed a questionnaire to obtain information approximately facial care products and various environmental factors. Our study revealed the use of moisturizer to be significantly higher in the FFA group compared to normal controls (p < 0.001), and sunscreen use was significantly higher in the PHL group than in the control group (adjusted p < 0.001). Subjects with FFA or PHL reported significantly higher use of both sunscreen and moisturizer compared to normal controls (p < 0.001). This study focused on Asian populations. Our results revealed a high frequency of moisturizer and sunscreen use in both FFA and PHL among Asian females. Therefore, the use of facial care products appears not to be linked to the true disease mechanism of FFA, but rather to appearance-related concerns of patients.

Abstract
BACKGROUND Moisturizers traditionally function to replenish both the intercellular lipid lamella and natural moisturizing factors, and form a hydrolipid film on the skin surface to decrease transepidermal water loss and improve hydration. As we continue to identify epidermal lipid imbalance in patients with atopic dermatitis, we turn to the use of bioactive ingredients in moisturizers for improving barrier repair and function. METHODS This review aims to explore the modern use of moisturizers in targeting various components of the skin barrier, dampening immune response, and restoring microbial balance. We conducted a balanced and comprehensive narrative review of the literature. Studies were identified by searching electronic databases (MEDLINE and PubMed), focusing on studies and trials regarding moisturizers that include endocannabinoids, bioactive lipids, anti-inflammatory agents, antioxidants, and microbiome modulators. Only articles published in English language were included. RESULTS The aforementioned ingredients exert additional biological effects to improve skin function by upregulating lipid synthesis, decreasing neurosensory transmission of itch signals, reversing oxidative stress, decreasing inflammatory cell activity and cytokine release, and modulating skin microbiota. The shift from traditional moisturizers to those with bioactive ingredients, anti-inflammatory agents, and microbiome modulating effects opens a realm of possible therapeutic options for patients with barrier-defective cutaneous conditions. CONCLUSION Focusing on the disrupted skin barrier as a target for both prevention and treatment and incorporating a combined strategy that utilizes the aforementioned agents to tackle barrier dysfunction from different angles remains a promising area for clinical impact in dermatology.

Abstract
Hand eczema is a major occupational disease, especially in medical workers, reducing their quality of life (QOL) and work productivity. Daily wearing of fabric gloves to prevent loss of moisture and lipids from the surface of the hands has been regarded as good in the management of hand eczema. However, limited evidence is available regarding the efficacy of moisturizing care with daily gloves on hand eczema. This pilot study was performed to evaluate the efficacy of moisturizing intervention with daily wearing of fabric gloves on skin barrier function, disease severity, and microbiome in health-care workers with hand eczema. Study 1: Nurses in the neonatal intensive care unit or growing care unit with and without hand eczema were recruited in the study. Subjects were instructed to apply moisturizer and wear two types of fabric gloves, common cotton gloves and moisturizing fabric gloves containing malate, for 4 weeks. Study 2: Physicians and health-care workers were recruited and instructed to wear a cotton glove on one hand at nighttime for 4 weeks. Disease severity, skin barrier function, QOL, and hand microbiome (Study 1) were evaluated. Study 1 found that daily wearing of both types of fabric gloves accompanied by use of topical moisturizers reduced the severity of hand eczema without changing the variation of microbiome. Study 2 found no apparent change between wearing and not wearing cotton gloves. In summary, topical moisturizer is of fundamental importance, and concomitant use of fabric gloves may merely enhance the efficacy of moisturizer in the management of hand eczema.

Abstract
Background The spread of COVID‐19 has made mask wear essential. Expecting that long‐term mask wear would change the characteristics of skin, this study investigated changes in skin wrinkles and pores caused by long‐term mask wear and whether or not use of moisturizers has an effect on any changes. Materials and methods The study participants were 20 women who were instructed to wear a mask for at least 6 hours a day for 4 weeks. Measurements of skin wrinkles and pores were obtained before and after the 4 weeks of mask wear. The effects of application of a moisturizer were assessed by applying moisturizer within the mask‐wearing area. They completed a questionnaire about skin changes at the end of the study period. Results After wearing the mask for 4 weeks, there was a significant increase in the skin wrinkles and pores; both variables decreased significantly in skin areas where a moisturizer had been applied. The results of the questionnaire‐based survey indicated the study participants considered that long‐term wearing of a mask had affected their skin. Conclusion Wearing a mask for extended periods increases skin wrinkles and pores and using a moisturizer when wearing the mask helps to reduce this problem.

Abstract
Vaginal dryness is common during and after menopause due to declining estrogen. It is one of the symptoms of vulvovaginal atrophy (VVA), which is part of the genitourinary syndrome of menopause. This can be distressing for women and cause pain, discomfort, and dyspareunia. Vaginal dryness affects over 50% of postmenopausal women but is under-reported and thus under-treated due to barriers to seeking help. Estrogen replacement can resolve symptoms, but may be contraindicated or not desired by all women. Over-the-counter vaginal moisturizers and lubricants can ease the symptoms of VVA. However, their chemical composition varies enormously and some are known to cause detrimental effects due to unphysiological pH, osmolality, and additives. The primary purpose of this review is to assess both their efficacy and safety. Women should be directed toward products that are as 'body-similar' as possible to vaginal secretions in terms of pH and osmolality. Products with potentially harmful ingredients should be avoided. Lubricants can be trialed for sexual activity and moisturizers for symptom control, even if topical or systemic menopause hormone therapy is being used.

Abstract
Psoriasis is a chronic, recurrent skin disease requiring long-term management. Agents that repair the skin's barrier function are invaluable additives in topical treatments of psoriasis. This multicenter, randomized, controlled trial evaluated the efficacy and safety of a linoleic acid-ceramide-containing moisturizer (LA-Cer) for mild-to-moderate psoriasis vulgaris. We randomized 178 patients from both northern and southern regions of China into two groups: 81 patients in the control group received mometasone furoate (MF, 0.1%) cream, while MF in combination with LA-Cer was administered to 86 patients in the treatment group for 4 weeks. The LA-Cer-MF group maintained the use of moisturizer after topical glucocorticoid administration. The primary endpoint, Psoriasis Area and Severity Index 50 (PASI 50) response, revealed the superiority of LA-Cer-MF with lower relapse rates at week 8. The use of the LA-Cer-containing moisturizer as maintenance therapy resulted in a continuous improvement in the clinical state in terms of body surface area, PASI, investigators' assessment of skin dryness and desquamation, and Physician Global Assessment of Psoriasis score, and in the patients' quality of life. Thus, the LA-Cer-containing moisturizer is a promising agent to prevent and treat psoriasis as it enhances the therapeutic effect induced by topical glucocorticoids and delays relapse.

Abstract
Background: Radiodermatitis is a frequent side effect of breast cancer radiotherapy (RT). Treating radiation oncologist should know the prevention and treatment of every grade of radiodermatitis. Aims: The aim of this study was to compare the topical corticosteroid and moisturizer usage in breast cancer RT. Materials and Methods: Fifty patients with early-stage breast cancer undergoing breast-conserving surgery referred to our department for adjuvant RT between October 2009 and October 2016 were compared with regard to topical steroid or moisturizer usage. Patients were followed up weekly after the start of treatment. Results: Mean age was 46 years. Twenty-four patients had stage 1 breast cancer and 26 patients had stage 2 disease. KPS (Karnofsky performance score) was 100 for all patients. Five patients (20.8%) had grade 2 and seven (29.1%) patients had grade 1 acute radiodermatitis in the first group. Eleven (42.3%) patients had grade 2 and 12 (46.1%) patients had grade 1 acute radiodermatitis in the second group. Thirteen (54.1%) patients in the first group had no acute radiodermatitis and three (11.5%) patients in the second group had no acute radiodermatitis. No patient in either group experienced grade 3 radiodermatitis. Conclusions: Daily use of topical betamethasone for breast cancer RT improves dermal sparing, reduces acute radiodermatitis, and may be recommended for patients receiving RT to the breast.

Abstract
BACKGROUND Heparinoid is a medication prescribed in Japan for skin diseases, such as atopic dermatitis and dry skin. Heparinoid prescription has increased with instances of internet blogs recommending its use as a cosmetic. OBJECTIVE This study aimed to examine the prescription trends in moisturizer use and analyze their association with internet searches. METHODS We used a claims database to identify pharmacy claims of heparinoid-only prescriptions in Japan. Additionally, we used Google Trends to obtain internet search data for the period between October 1, 2007, and September 31, 2017. To analyze the association between heparinoid prescriptions and internet searches, we performed an autoregressive integrated moving average approach for each time series. RESULTS We identified 155,733 patients who had been prescribed heparinoid. The number of prescriptions increased from 2011 onward, and related internet searches increased from 2012 onward. Internet searches were significantly correlated with total heparinoid prescription (correlation coefficient=.25, P=.005). In addition, internet searches were significantly correlated with heparinoid prescription in those aged 20-59 years at -1-month lag in Google Trends (correlation coefficient=.30, P=.001). CONCLUSIONS Google searches related to heparinoid prescriptions showed a seasonal pattern and increased gradually over the preceding several years. Google searches were positively correlated with prescription trends. In addition, in a particular age group (20-59 years), prescriptions increased with the increase in internet searches. These results suggest that people obtained health-related information on the internet and that this affected their behavior and prescription requests.

Background: Ceramides are epidermal lipids that play an essential role in stratum corneum function, including maintaining physiologic permeability barrier properties. The role of ceramides in the maintenance and repair of epidermal barrier function is believed to be valuable in the treatment of psoriasis. Normalization of corneocyte desquamation and the incorporation of agents that promote desquamation to reduce hyperkeratosis are also regarded as key factors in psoriasis management. Objective: We sought to evaluate the benefits of two formulations (CeraVe® Body Cleanser [Cer-PSO-BCl] and CeraVe® Body Cream [Cer-PSO-Cr]), containing ceramides, salicylic acid, and urea in patients with a history of psoriasis, including those with mild-to-moderate psoriatic flares. Methods: This was a two-center customer usage study involving 33 male and female subjects, 18 years of age or older, with a history of mild-to-moderate psoriasis. Cer-PSO-Cr was applied liberally wherever psoriasis was present twice a day for two weeks. Cer-PSO-BCl was recommended for use twice a week. Product attributes, performance of individual test products, and use of this combination regimen (favorable or unfavorable) were assessed using a self-assessment questionnaire at Week 2. Results: Overall, 72.7 and 75.8 percent of patients with psoriasis reported the Cer-PSO-Cr alone or Cer-PSOCr/Cer-PSO-BCl regimen improved the appearance of their skin. For the cleanser, 97.0 percent reported it rinsed clean with no unpleasant residue. For cream and cleanser together, 84.8 percent reported it provided relief of psoriasis, and 90.9 percent reported that their skin felt soft and smooth. Conclusions: Based on results reported by the study patients, the evaluated ceramide/keratolytic-containing cream and cleanser both yielded a high level of patient acceptance regarding improvement in skin characteristics in patients with psoriasis, including when used as a combination adjunctive regimen.

Abstract
Background In dialysis patients, skin disorders (dryness and itching) are frequently observed and treated with a moisturizer, in the absence of clear evidence of efficacy. Study Design An open-label, randomized, before/after, parallel-group, comparative/exploratory study. Setting & Participants 12 Japanese patients with chronic kidney failure undergoing maintenance hemodialysis who presented with dry skin and itching. Intervention Patients received a topical heparinoid moisturizer as the study drug for 2 weeks from the first day of the study treatment, followed by either a 2-week washout (group A: 6 participants) or further 2-week treatment (group B: 6 participants). Outcomes The primary end point was change in water content in the stratum corneum in the hypochondrium. Secondary end points included change in visual analogue scale itching score and subjective evaluations of symptoms. To evaluate safety, adverse events were also investigated. Measurements Water content of the stratum corneum, dryness/itching improvement rating, itching visual analogue scale/duration of itching, photographic evaluation of skin symptoms, principal investigator’s overall assessment of study drug, and adverse events. Results Mean water content of the stratum corneum in the combined groups significantly increased at week 2 (51.2 arbitrary units [AU] vs treatment start day, 31.6 AU; P<0.001), but significantly decreased at week 4 in group A, in which patients discontinued treatment with the study drug (39.4 AU; P = 0.005). Other efficacy end points, including the visual analogue scale itching score, were also improved by treatment with the study drug, but such improvement was not sustained after discontinuation of treatment. There were no adverse events related to the study treatment. Limitations Only Japanese patients were included in the study, with a small sample size. Conclusions Continuous application of the topical heparinoid moisturizer increased water content in the stratum corneum and lessened itching in dialysis patients. Funding Maruho Co, Ltd.

Exploratory study to evaluate two clinical methods for assessing moisturizing effect on skin barrier repair. Skin Res Technol 2019; 25:251-257. [PMID: 30937980 PMCID: PMC6850322 DOI: 10.1111/srt.12632] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Accepted: 09/24/2018] [Indexed: 11/30/2022]
Abstract
Background Two clinical methods of assessing a moisturizer's effect on stratum corneum (SC) barrier repair were evaluated in female subjects with dry skin, to identify an assessment method for future studies. Methods In this single‐centre, split‐body study, women with dry skin applied moisturizer before (method A) or after (method B) SC barrier perturbation using D‐Squame® stripping discs. Transepidermal water loss (TEWL) and residual protein on D‐Squame discs were assessed over 14 days. Results Twenty‐four subjects were included. For method A, the mean slope values of plots of 1/TEWL vs cumulative protein removed decreased over time for both treated and untreated areas, indicating improved SC barrier quality. There were no significant differences between treated and untreated areas, although a trend to a more negative slope was observed by Day 14 in the treated areas (P = 0.082), suggesting treatment improved barrier quality. For method B, using pre‐ and post‐stripping as covariates, no statistical differences/trends were observed between treated and untreated areas for change in TEWL from post‐stripping to any evaluation from Days 3‐14. TEWL values returned towards pre‐stripping values for treated and untreated areas by the initial Day 3 evaluation. Conclusion For method A, there were trends suggesting the moisturizing treatment improved SC barrier quality. For method B, there were no significant differences/trends between treated and untreated areas. Further assessment with different methodologies is warranted to design appropriate clinical protocols for evaluating accelerated skin barrier repair. These data are insufficient to conclude whether the product or methodology was responsible for the results.

A novel moisturizer with high sun protection factor improves cutaneous barrier function and the visible appearance of rosacea-prone skin. J Cosmet Dermatol 2019; 18:1686-1692. [PMID: 30803131 PMCID: PMC6916358 DOI: 10.1111/jocd.12889] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2018] [Revised: 08/10/2018] [Accepted: 12/14/2018] [Indexed: 01/11/2023]
Abstract
Background Consensus guidelines advocate general skincare for rosacea patients. Objectives Two independent studies were performed to assess whether a tinted daily SPF‐30 facial moisturizer (DFM30) improves barrier function of dry skin and the efficacy and tolerability of DFM30 on rosacea‐prone skin. Methods In study 1, electrical capacitance (EC) and transepidermal water loss (TEWL) were measured at baseline, 2, 4, 8, and 24 hours after a single application of DFM30 and on a control site in 21 healthy females with dry skin. Study 2 evaluated 33 females with mild to moderate rosacea and nontransient erythema. Efficacy and tolerability after once‐daily DFM30 were assessed using a chromameter, image analysis of photographs, and trained rater and patient evaluations up to day 22. Results In study 1, EC showed statistically significant increases at 2, 4, and 8 hours, and TEWL showed statistically significant decreases 2, 4, 8, and 24 hours after DFM30 application to healthy females compared to baseline. In study 2, covering skin redness improved significantly after DFM30 application on day 1; 33.3% showed improved covering skin redness compared to baseline. Patients reported significantly less redness on day 8 than day 3. Feelings of dryness and tightness/tension were lower 30 minutes after first application. Feeling of dryness was lower than baseline after 3 days, 1 and 3 weeks. Image analysis suggested redness was significantly lower on day 22 compared to baseline. Chromameter readings showed significantly lower erythema on the cheek compared to baseline. All patients stated that DFM30 relieves and neutralizes visible redness who also indicated that they would purchase DFM30, and the product was well tolerated. Conclusions These studies show that DFM30 is suitable as part of the skincare regimens advocated by ROSacea COnsensus (ROSCO) for rosacea patients. DFM30 is an effective moisturizer that improves cutaneous barrier function and the appearance of rosacea‐prone skin.

Abstract
Background Acne vulgaris is a common and chronic disease that impacts on physical and psychological perceptions. Cosmeceutical products are widely used as adjunct therapy to standard treatments. Objective To evaluate the efficacy of cosmeceutical products comprising glycolic acid, salicylic acid, gluconolactone, and licochalcone A as adjunct therapy to adapalene in mild-to-moderate acne vulgaris. Materials and methods A 28-day, double-blind, within-person comparative study was conducted with a total of 25 subjects. Each participant received two products, consisting of (1) a cosmeceutical product mixed with 0.1% adapalene, and (2) 0.1% adapalene, and was asked to apply them separately on each hemi-side once nightly for 28 days. The number of acne lesions, severity of acne vulgaris, physician’s and patient’s global assessment of acne severity, visual analog scale of radiance, skin biophysics, safety assessment, and VISIA® camera system were evaluated. The primary efficacy outcome was to compare the reduction of inflammatory lesions between two treatments at day 7 by using non-inferiority comparison. Results The mean differences of inflammatory lesions reduction at day 7 between the two groups was 0.391 (90% CI = 0.253–0.530). The differences between two groups fell within our acceptable margin for the 90% CI. The spot score from VISIA® showed higher statistically significant improvement in the combination side. Conclusion The results showed no hindrance of using a cosmeceutical combined with standard treatment. Nevertheless, this cosmeceutical product showed some benefits in reducing complications from acne. Clinical trial registration Thai Clinical Trials Registry (primary site), no. TCTR20171031005.

[PMID: 30700045 PMCID: PMC6406490 DOI: 10.3390/children6020017] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Revised: 01/22/2019] [Accepted: 01/22/2019] [Indexed: 12/21/2022]
Abstract
Atopic dermatitis (AD) is a chronic cutaneous inflammatory disorder, characterized by skin barrier disruption. Dermacare is a new cosmetic formulation, which enhances moisturization, reinforces and repairs the skin barrier, and prevents cutaneous microbiota imbalance. To demonstrate its safety and efficacy, a prospective, open-label, and multicenter study was carried out on patients diagnosed with mild to moderate AD. Transepidermal water loss (TEWL), clinical severity, Desquamation Index, Patient/Investigator Global Assessments, quality of life index, and tolerance were assessed. Adverse events were recorded. Daily application of the new treatment was well tolerated, and adverse events were absent. After 14 days, TEWL showed a 36.7% significant decrease (p = 0.035). At the end of the 28-day treatment, the Desquamation Index showed a reduction in 70% of patients; Eczema Area and Severity Index were reduced by 70.4% (p = 0.002); and skin irritation showed a significant reduction (p = 0.024). Likewise, Patient and Investigator Global Assessments reported a significant improvement in conditions and an overall global worsening when patients restarted their normal treatment. Parent's Index of Quality of Life Index significantly increased by 36.4% (p < 0.05) with Dermacare. In conclusion, a regular use of this new formulation can reduce the risk of relapse and extend the steroid-free treatment periods.

Abstract
BACKGROUND Eczema or atopic dermatitis (AD) is a common relapsing childhood dermatologic illness. Treatment of AD is primarily topical with emollients and corticosteroid/calcineurin inhibitor, which is efficacious for the majority of patients. However, AD is often complicated and difficult to manage in many Asian cities. Effective therapy is impeded by fallacies in the following aspects: (1) mistrust and unrealistic expectations about Western medicine, (2) skin care and allergy treatment, (3) ambiguity about optimal bathing and moisturizing, (4) hesitation and phobias about the usage of adequate topical corticosteroid and immunomodulatory therapies, (5) food and aeroallergen avoidance and dietary supplementation, and (6) complementary and alternative therapies. METHODS AND RESULTS Eleven anonymized case scenarios are described to illustrate issues associated with these fallacies. A literature review is performed and possible solutions to handle or dismiss these fallacies are discussed. CONCLUSIONS The first step in patient care is to accurately assess the patient and the family to evaluate possible concerns, anxiety, and phobias that could impede therapeutic efficacy. Education about the disease should be individualized. Conflicting recommendations on the usage of topical steroid have a detrimental effect on management outcomes, which must be avoided.

Abstract
Background: Pentasodium tetracarboxymethyl palmitoyl dipeptide-12 (PTPD-12), a newly-synthesized peptide, enhances the autophagy activity, ultimately managing inflammation. Objective: To determine the effect of a new moisturizer containing PTPD-12 as the treatment of mild-to-moderate atopic dermatitis (AD). Methods: In this double-blind, randomized, placebo-controlled trial, 43 patients with mild-to-moderate AD were randomly assigned to either the PTPD-12 or control groups. Evaluations were performed at baseline, week 2, and week 4, including SCORing Atopic Dermatitis (SCORAD) index score, corneometry, trans-epidermal water loss (TEWL), visual analog scale (VAS) for pruritus, 7-point investigator's global assessment (IGA), and collection of adverse events. Results: The PTPD-12 group showed significant improvement with respect to SCORAD score, skin hydration, TEWL, and pruritus at weeks 2 and 4 when compared with baseline. Although the control group showed significant improvement regarding the SCORAD score and skin hydration, no significant change in TEWL or pruritus was demonstrated throughout the study. The mean changes in the SCORAD index score, skin hydration, TEWL, pruritus, and number of patients with improvement in IGA were not statistically different between the two groups. Conclusion: The moisturizer with autophagy-stimulating property provides a good therapeutic option to mild-to-moderate atopic dermatitis by contributing to skin barrier restoration and control of inflammation.

Abstract
Alterations in barrier function are associated with a number of skin diseases, including xerosis, atopic dermatitis, and psoriasis. Urea, a component of the natural moisturizing factor of the skin, plays an important role in the preservation of skin hydration and integrity. Several studies have investigated the effects of urea in the clinical setting. Here, we summarize the available clinical evidence regarding the effects of urea in the maintenance of healthy skin and management of skin disorders. At lower doses (≤10%), urea-containing topical formulations act as a skin moisturizer, while at higher concentrations (>10% urea), urea-based preparations exert a keratolytic action. Urea is also useful in combination therapies with anti-inflammatory and anti-fungal drugs, due to its activity as a penetration enhancer.

Abstract
Background Moisturizers are topical products designed to improve and maintain the skin barrier function and to help prevent dry skin. Materials and methods A new moisturizer (Ceramide cream) was formulated containing ingredients which mimic the skin's own natural moisturizing systems. Corneometry was performed at baseline, 2, 4, 6 and 24 hours following a single application of Ceramide cream to healthy skin, and compared to three reference moisturizers available over-the-counter, and placebo. Transepidermal water loss (TEWL) was also measured following a single application of Ceramide cream compared to baseline, and its safety was assessed by repeat insult patch test, ophthalmologist and pediatric testing. Results A single topical application of either the Ceramide cream or the three reference moisturizers resulted in a significant increase in skin hydration over time (P<0.001). The placebo cream did not significantly increase skin hydration at any time point. At 24 hours post-application, skin hydration measured for Ceramide cream was significantly greater (P<0.05) than that measured for all three of the reference moisturizers tested. Ceramide cream was also found to significantly decrease TEWL (P<0.001) over 24 hours, and was shown to be non-sensitizing to the skin of both adults and children and non-irritating to the skin, eyes and related eye area. Conclusion Ceramide cream increases skin hydration and improves barrier function which may make it suitable for use on dry skin.

A cross-sectional survey of methods for controling hand-foot syndrome in patients receiving capecitabine treatment. Mol Clin Oncol 2018; 9:443-448.

Abstract
Medical personnel actively provide patients taking capecitabine with information on the items to prevent and treat hand-foot syndrome (HFS). However, they are typically unable to ascertain the extent of patient compliance with the recommended items. Thus, the aim of the present study was to ascertain the association between patient compliance with preventative measures for HFS and the development of HFS. Subjects included 90 patients who were treated with a drug regimen that included capecitabine. Patients were treated at one of four facilities between July 2015 and January 2017. The main parameters studied were the extent to which items to prevent and treat HFS were (or were not) followed, and the associaiton between this extent and the development of HFS symptoms. A manual prepared by a pharmaceutical company that manufactures capecitabine describes 15 routine items to follow in order to prevent and treat HFS. The two activities patients most often performed were 'applying a moisturizer' (74.1%) and 'keeping one's skin clean (e.g., washing one's hands and feet)' (64.7%). The two activities patients least often performed were 'using sunscreen on exposed areas' (14.1%) and 'using soft insoles' (11.8%). Patients who performed more items to prevent and treat HFS were significantly less likely to develop symptoms of HFS (P=0.022). Based on these findings, it is recommended that medical personnel provide instructions to the patients regarding the specific items necessary to prevent and treat HFS, and to follow-up with the patients regarding their compliance, with an emphasis on the items they are less likely to take and on the instructions to avoid external irritants. Following these guidelines should lead to qualitative improvement in HFS management.

Abstract
Nutraceuticals are important for healthy skin maintenance. Probiotics, phenolics, and vitamins are just a few of the nutraceuticals meant to potentially prevent and assist medical management of dermatologic conditions. Among these, probiotics, vitamin E, and green tea catechins may offer the broadest array of skin protective mechanisms with probiotics having the greatest clinical range. Probiotics’ amelioration of atopic dermatitis and opportunistic infections of skin burns has been targeted in recent research efforts. This includes the improvement of Scoring Atopic Dermatitis index scores, p = 0.02, with intact Lactobacillus rhamnosus Goldin and Gorbach (LGG) in comparison to heat inactivated LGG or placebo. Lactobacillus reuteri used prior to or concurrently with Staphylococcus aureus infection can increase epidermal keratinocyte survival, p < 0.01. Phenolics may not have been extensively studied for atopic dermatitis or skin burns. However, phenolics do have a role in photoprotection. The phenolic rutin increases ultraviolet B radiation filter reactive oxygen species scavenging at 75%, p < 0.002, and peak wavelength absorption, p < 0.001. While oral and topical probiotics have untapped potential for atopic dermatitis amelioration and skin infection prevention, phenolics will be increasingly used for photoprotection. With optimized bioavailability, dosage, and formulation, nutraceuticals will become crucial for healthy skin maintenance.

Abstract
The epidermis contains epithelial cells, immune cells, and microbes which provides a physical and functional barrier to the protection of human skin. It plays critical roles in preventing environmental allergen penetration into the human body and responsing to microbial pathogens. Atopic dermatitis (AD) is the most common, complex chronic inflammatory skin disease. Skin barrier dysfunction is the initial step in the development of AD. Multiple factors, including immune dysregulation, filaggrin mutations, deficiency of antimicrobial peptides, and skin dysbiosis contribute to skin barrier defects. In the initial phase of AD, treatment with moisturizers improves skin barrier function and prevents the development of AD. With the progression of AD, effective topical and systemic therapies are needed to reduce immune pathway activation and general inflammation. Targeted microbiome therapy is also being developed to correct skin dysbiosis associated with AD. Improved identification and characterization of AD phenotypes and endotypes are required to optimize the precision medicine approach to AD.

Abstract
Background Application of topical moisturizers is an essential part of the management of atopic dermatitis (AD). Linoleic acid (LA), the most abundant fatty acid in the epidermis, and its derivatives have an essential role in the structure and function of the epidermal barrier, and their defects are prominent in AD. The aim of this study was to compare the efficacy and safety of two cosmetic products containing either LA or urea in patients with AD. Patients and methods A total of 20 patients with AD who met the eligibility criteria and provided written informed consents were enrolled in this randomized, intra-individual split-body, single-center trial. Symmetrical lesions of patients were randomized for treatment with LA- or urea-containing water-in-oil (w/o) emulsions applied two to three times daily for 4 weeks. The efficacy of the two products was evaluated by local Scoring Atopic Dermatitis (SCORAD) of both lesions and also patient (or guardian) satisfaction. In addition, trans-epidermal water loss (TEWL), stratum corneum (SC) hydration, pH, sebum, temperature, erythema, melanin content, and ultrasonographic thickness and echo density of epidermis and dermis were measured before, and 2 and 4 weeks after, treatment. Results Four weeks of treatment with the LA-containing product resulted in a significant decrease in local SCORAD, TEWL, erythema, and echo density of dermis, as well as an increase in SC hydration compared to baseline. The urea-containing product also reduced the local SCO-RAD and echo density of dermis and increased SC hydration. In contrast to the LA-containing product, changes in TEWL and erythema were not significant. Moreover, the reduction of erythema was significantly higher in the LA-containing product-treated side compared to the urea-containing product-treated side (p = 0.006). Conclusion Both LA- or urea-containing w/o emulsions can significantly improve barrier dysfunction and clinical severity of AD. In agreement with literature, it was confirmed that an LA-containing w/o emulsion exhibited erythema-reducing effects. Since emollients should be used on a regular basis, patients should choose a product by individual preference following recommendation by their dermatologists.

Abstract
AIM Eczema or Atopic Dermatitis (AD) is associated with itch, sleep disturbance, impaired life quality, reduced skin hydration, impaired epidermal barrier function and colonization by Staphylococcus aureus (SA). We investigated an emollient with claimed multi-actions on barrier repair, antihistaminergic and antimicrobial effects. METHODS Consecutive AD patients were recruited. Swabs and cultures from eczematous areas, disease severity (SCOring Atopic Dermatitis score: SCORAD), quality-of-life (Children Dermatology Life Quality Index, CDLQI), Skin Hydration (SH), and Transepidermal Water Loss (TEWL) were obtained before and 4-week following usage of the emollient. Global or General Acceptability of Treatment (GAT) was obtained (as very good, good, fair or poor). RESULTS 30 AD patients were recruited. 73% reported "very good" or "good", whereas 27% reported "fair" or "poor" GAT of the emollient. Following the use of the multi-action emollient, area affected, disease intensity and severity significantly improved, especially in the very good/good group (p=0.006-0.035). There was no significant improvement of itch or sleep scores, quality of life, SH, TEWL, S. aureus colonization status, or use of topical treatments. When compared with the historical data of another product, there was no statistical difference between the two creams. CONCLUSION The emollient is acceptable in nearly three-quarter of AD patients. Patients that accept the moisturizer have less area affected, disease intensity and severity than the non-accepting counterparts following its usage. Despite claim for multi-action, there were no appreciable quality-oflife, anti-itch, skin barrier, and anti-microbial effects.

Abstract
Aims Limited data regarding the objective evaluation of skin exsiccation caused by epidermal growth factor receptor (EGFR) inhibitors exist. Objective indices were applied to evaluate the usefulness of a moisturizer against skin exsiccation associated with the use of EGFR inhibitors in cancer patients. Patients and methods Patients with either colorectal or head and neck cancer treated with either cetuximab or panitumumab were randomly assigned 1:2 to the prophylactic-treatment arm, where participants received prophylactical moisturizer treatment (heparinoid preparation, Hirudoid®), or to the symptomatic-treatment arm, where moisturizer was applied after the onset of cutaneous symptoms. Patients were observed for 6 weeks after the start of the administration of EGFR inhibitor. Results A total of 15 patients were included and assessed: 6 in the prophylactic treatment group and 9 in the symptomatic treatment group. We evaluated the effect of EGFR inhibitors on the physiologic function of the skin. Administration of EGFR inhibitors resulted in a continued reduction in the moisture content of the horny layer and a decrease in cutaneous sebum levels. Skin observation revealed frequent development of an acneiform rash and significantly higher exsiccation and exfoliation scores. Administration of EGFR inhibitor was associated with a decrease in the horny layer moisture content and lower cutaneous sebum levels in the symptomatic treatment group. In contrast, levels of both the indicators were increased in the prophylactic treatment group. Moreover, the EGFR inhibitor-associated increase in exsiccation and exfoliation scores were minimized in the prophylactic treatment group relative to the symptomatic treatment group. Conclusion Application of a moisturizer is effective against dry skin induced by the administration of an EGFR inhibitor.

Abstract
PURPOSE To identify factors perceived as most important regarding choice and continued use of moisturizers for adult patients with AD. METHOD AND MATERIALS Online survey among members of the Atopic eczema society Denmark. RESULTS Among 75 participants, the most commonly tried (89.3%) and preferred (16%) product was Locobase® (Leo Pharma, Denmark). A-derma® (Pierre Fabre, France) had most continued use. The main reason for choosing preferred product was 'Best effect, in my experience' (36%). 'High lipid content' and 'GP/dermatologist suggested product' were considered as important main factors. 'Consistency', 'absorbs fast', and 'nice to wear' were secondary reasons for preferred product. A majority, 81.3% of respondents claimed to be very aware of perfumes and additives, 52% were very aware of allergy certification bodies on the product. CONCLUSION AD patients state that the most important factor when choosing a product is out of personal experience followed by high lipid content and recommended by GP/dermatologist. As secondary reasons 'consistency', 'absorbs fast', and 'nice to wear' were important. Respondents generally use more than one product and are aware of additives. Evidence-based guidance on the choice of emollients is needed. The role of the professionals supporting the patient in navigating this market of emollients is therefore particularly important.

Abstract
Background This study examines the efficacy of a new plant-based emollient and assesses product acceptability. Methods Primary efficacy endpoints were improvement in transepidermal water loss, hydration, skin elasticity and firmness, erythema, and skin roughness and smoothness as measured using the versions of Tewameter, Corneometer, Cutometer, Mexameter, and Visioscan VC98, respectively. The cream was applied twice daily by 32 participants to an area of one forearm unaffected by eczema, while the same area of the other forearm was used as a control. Measurements were taken at day 0 and day 14. Secondary endpoints assessed the acceptability of the product. Results At the end of 2 weeks, transepidermal water loss, hydration, skin elasticity and firmness, erythema, and skin roughness and smoothness improved. All changes were statistically significant (p<0.01). The rate of satisfaction with the emollient properties was 82%, and the rate of absorption into the skin was 88%. Results show that the emollient hydrates and repairs eczema-prone skin with high levels of acceptability.
