Yoon EJ, Kwon EH, Kim JH, Delacruz J, Symons TB, Lee S, Park D. Influence of cosmetic foundation cream on skin condition during treadmill exercise. J Cosmet Dermatol 2024; 23:1884-1890. [PMID: 38444348 DOI: 10.1111/jocd.16205] [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: 11/04/2023] [Revised: 01/11/2024] [Accepted: 01/22/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND There is a growing trend of individuals wearing cosmetics while participating in physical activities. Nonetheless, there remains a need for further understanding regarding the effects of makeup on the facial epidermis during exercise, given the existing knowledge gaps. PURPOSE This study aimed to evaluate the effects of a cosmetic foundation cream on skin conditions during physical activity. METHODS Forty-three healthy college students, 20 males (26.3 ± 1.5 years) and 23 females (23.1 ± 1.0 years), were enrolled in this study. Foundation cream was applied to participants on half of the face in two different areas (MT: makeup T zone and MU: makeup U zone). The other half of the face served as internal control (T: non-makeup T zone and U: non-makeup U zones). Skin levels of moisture, elasticity, pore, sebum, and oil were measured using a skin analysis device (Aramhuvis, Gyeonggi, Republic of Korea) before and after a 20-min treadmill exercise. Paired t-test and independent t-test were performed for skin condition measurements at pre- and postexercise. RESULTS The skin moisture levels in both the T and MT significantly increased after exercise (p < 0.05) (pre-T: 24.5 ± 1.3, post-T: 38.5 ± 3.5 and pre-MT: 18.7 ± 0.7, post-MT: 40.4 ± 4.8). Elasticity also significantly improved in both the T and MT (p < 0.05) (pre-T: 25.6 ± 1.3, post-T: 41.5 ± 3.5 and pre-MT: 20.0 ± 0.9, post-MT: 41.7 ± 3.7). The size of the pores in the T zone observed a significant increase after exercise (p < 0.05) (pre-T: 41.7 ± 2.1, post-T: 47.8 ± 2.4). The sebum levels in the T zone exhibited a reduction following physical activity, whereas there was a notable increase in sebum levels in the makeup zones (p < 0.05) (pre-MT: 2.4 ± 0.7, post-MT:4.2 ± 0.8 and pre MU 1.8 ± 0.34, post MU 4.9 ± 0.9). The oil level was increased in the non-makeup zones (pre-T: 6.1 ± 1.4, post-T: 11.8 ± 2.0 and pre-U: 7.3 ± 1.5, post-U: 11.9 ± 1.9; p < 0.05) and decreased in the makeup zones (pre-MT: 13.3 ± 1.9, post-MT: 7.4 ± 2.3 and pre-MU: 22.1 ± 2.4, post-MU: 3.2 ± 1.0; p < 0.05). CONCLUSIONS The findings suggest that using foundation cream during aerobic exercise can reduce skin oil, causing dryness. Additionally, makeup can clog pores and increase sebum production. Therefore, wearing makeup may not be recommended for people with dry skin conditions based on the results of the current study. This research offers important insights to the public, encouraging them to consider the possible consequences of using makeup while exercising.

Photodiagnosis Photodyn Ther 2024; 45:103973. [PMID: 38316341 DOI: 10.1016/j.pdpdt.2024.103973] [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: 12/14/2023] [Revised: 01/09/2024] [Accepted: 01/12/2024] [Indexed: 02/07/2024]
Abstract
BACKGROUND Seborrhea poses a common cosmetic concern in adolescents and young adults, often accompanied by enlarged pores, and contributing to various skin conditions, including acne vulgaris and seborrheic dermatitis. At present, there is a lack of effective treatment for this problem, and the potential of photodynamic therapy (PDT) in reducing sebum remains inconclusive. OBJECTIVE This exploratory, prospective, single-center, double-blinded, randomized split-face controlled trial aimed to compare the efficacy and safety of intense pulsed light-photodynamic therapy (IPL-PDT) versus IPL therapy for seborrhea. METHODS Participants with seborrhea underwent 3 times of IPL treatment (590 nm, 15-17 J/cm2 based on patient's tolerance) for one hemifacial part and IPL-PDT treatment for the other. Follow-up assessment was conducted up to 8 weeks after the final treatment. RESULTS Compared with single IPL treatment, IPL-PDT can significantly inhibit sebum secretion and decrease pore size. PDT group exhibited no additional damage to the skin barrier, with even lower transepidermal water loss (TEWL). Additionally, the PDT group showed superior improvement in scores of porphyrins, red areas, and ultraviolet (UV) spots. Both groups experienced only mild topical adverse effects, well tolerated by the participants. CONCLUSION IPL-PDT is a more effective method than IPL in the treatment of seborrhea, as well as on the improvement of the skin barrier function.

[PMID: 37555304 DOI: 10.1111/jocd.15956] [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: 06/04/2023] [Revised: 07/17/2023] [Accepted: 08/01/2023] [Indexed: 08/10/2023]
Abstract
BACKGROUND Enlarged facial pores are a common cosmetic concern of the skin, rather than a disease, and have not received much attention from dermatologists in recent years. Consequently, progress in understanding their pathogenesis has been limited, and current cosmetic solutions have limitations. Given that the complement system has regained interest as a key player in chronic inflammatory skin conditions, various mechanisms involving this system are being investigated. OBJECTIVE We aimed to shed light on the mechanism underlying enlarged facial pores by examining the role of the complement system in skin. METHODS We conducted a comprehensive literature search utilizing various academic databases including PubMed, Web of Science, and Google Scholar. Employing keywords such as "complement system," "inflammation," "facial pores," "enlarged," and "mechanisms," we compiled a selection of relevant studies. These studies provided a comprehensive understanding of the intricate mechanisms underlying the relationship between the "complement system" and "inflammation" within the context of facial pore enlargement. RESULTS Our findings suggest that inflammaging mediated by complement activation may be a critical player in the formation of enlarged facial pores. Specifically, overactivation of the complement system leading to the accumulation of complement fragments could be a major contributor to this process. Notably, the complement system in skin may be involved in a range of skin issues, including aging. CONCLUSION Modulating the complement system presents a promising avenue for future research in improving skin health. Further basic and clinical research is necessary to validate these findings, but we hope that this study can serve as a theoretical foundation for the development of targeted cosmetics.

Abstract
BACKGROUND Excessive sebum production is a factor in acne development. Tazarotene 0.045% lotion has demonstrated reductions in acne lesions and acne-induced sequelae. OBJECTIVE Evaluate efficacy, changes in skin oiliness, and safety with tazarotene 0.045% lotion in participants with moderate-to-severe acne and oily skin. METHODS In two phase 3, double-blind, 12-week studies (NCT03168321; NCT03168334), participants aged ≥ 9 years with moderate-to-severe acne were randomized 1:1 to once-daily tazarotene 0.045% lotion or vehicle lotion (N = 1614). This pooled, post hoc analysis included only participants self-categorized with oily skin at baseline on the Acne-Specific Quality of Life questionnaire item 19 (scores: 0 [extremely oily] to 6 [not at all oily]). Inflammatory/noninflammatory lesion counts, treatment success, skin oiliness, treatment-emergent adverse events (TEAEs), and cutaneous safety/tolerability were evaluated. RESULTS In all participants with oily skin (n = 793), tazarotene provided greater reductions in inflammatory/noninflammatory lesions (p < 0.001, both) and greater treatment success rates versus vehicle (p < 0.01) at week 12. Over two-thirds of polymeric lotion-treated participants had subjective skin oiliness reductions by week 12, with around a third reporting 'low/not' oily skin. Tazarotene TEAE rates were similar to the overall population. CONCLUSIONS Once-daily treatment with tazarotene 0.045% polymeric emulsion lotion may help improve patient-perceived skin oiliness in those with moderate-to-severe acne.

Nonablative monopolar radiofrequency for the reduction of facial pores and sebum excretion in Thai patients: A novel approach. Lasers Surg Med 2023; 55:528-535. [PMID: 37210600 DOI: 10.1002/lsm.23681] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 05/07/2023] [Accepted: 05/11/2023] [Indexed: 05/22/2023]
Abstract
BACKGROUND Enlarged facial pores are visible topographic features of the skin that have been associated with cutaneous photoaging and increased sebum production. It has remained a common dermatologic concern, gaining a significant number of in-clinic consults. Available treatment modalities often operate on a single mode of action, consequently offering limited and short-term outcomes. OBJECTIVE This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) for pore tightening and sebum output reduction in Thai patients. METHODS Nineteen patients with enlarged pores underwent two sessions of NMRF treatments at 4-week intervals. The measurements of pore volume, skin texture, average pore size, sebum production, and skin elasticity were quantified using Antera® 3D imaging system, dermoscopic image analysis with ImageJ software, Sebumeter® and Cutometer®. Clinical evaluation by two dermatologists was done using blinded clinical photographs. All objective and subjective assessments were done at the baseline, a month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment. Adverse effects were also recorded during each visit. RESULTS Seventeen out of the 19 subjects completed the study protocol. The mean pore volume significantly reduced by 24% from the baseline at 1 month after the first treatment (p < 0.016). The pore volume continued to decrease by 34% and 38% a month (p < 0.001) and 6 months (p < 0.001) following the final treatment, respectively. Sebum excretion likewise significantly decreased from baseline by 39% (p = 0.002) and 36% (p < 0.001), 3 and 6 months after the second treatment, respectively. Skin texture and elasticity also significantly improved following two NMRF sessions. The objective assessments of the pore appearance corresponded to subjective clinical evaluations. The treatment was well-tolerated without significant side effects, such as dyspigmentation, textural alteration, and scarring. CONCLUSION NMRF appears to be effective and safe for the reduction of pore size and sebum production, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

Abstract
Background Despite the increasing need for the improvement of enlarged facial pores, the treatment remains challenging. A few previous studies have reported the effects of micro-focused ultrasound with visualization (MFU-V) or intradermal incobotulinumtoxin-A (INCO) on enlarged facial pores. Objective To evaluate the efficacy and safety of combined treatment with superficial MFU-V and intradermal INCO for enlarged facial pores. Methods This single-center retrospective study included 20 patients treated with MFU-V and intradermal INCO to improve enlarged facial pores. Outcomes were evaluated 1, 4, 12, and 24 weeks after a single session of the combined procedure. Pore count and density were objectively quantitated using a three-dimensional scanner, and improvement was assessed using the physician and patient Global Aesthetic Improvement Scale (GAIS). Results The mean pore count and density decreased after one week and decreased by up to 62% until 24 weeks. After one week, almost all patients (100% in physician GAIS and 95% in patient GAIS) showed improvement with a grade 3 (much improved) or higher. All adverse events were transient. Conclusion Combined treatment with MFU-V and intradermal INCO could be effective and safe for reducing enlarged facial pores; the improvements can be sustained for up to 24 weeks.

Abstract
BACKGROUND Treatment of acne scarring in darker skin types is fraught with challenges. Highly purified liquid injectable silicone (LIS) is effective in the treatment of acne scars, although its use in darker skin types has yet to be evaluated. OBJECTIVE Retrospective evaluation of the safety and efficacy of highly purified LIS for the treatment of acne scars in lighter and darker skin types. MATERIALS AND METHODS A retrospective chart review of patients who received highly purified LIS for acne scars between July 2010 and March 2021. RESULTS Two hundred six total treatments in 96 patients, 32.29% ( n = 31) of whom were Fitzpatrick skin type IV ( n = 20, 20.83%) and V ( n = 11, 11.46%), with depressed and both broad-based and shallow acne scarring were reviewed. Mean age was 50.77 years (SD 16.77), and 83% were female. Complications such as granuloma formation, migration, extrusion of silicone, hyperpigmentation, hematoma, or infection were not observed. The average follow-up time was 6.31 years (SD 3.02). CONCLUSION Highly purified LIS is a safe and effective permanent treatment for acne scars in all skin types. Injection of highly purified LIS using small volume microdroplet technique at 6- to 8-week intervals did not yield any complications, including in patients with darker skin types.

Abstract
INTRODUCTION Sebum-based metabolomics (a subset of "sebomics") is a developing field that involves the sampling, identification, and quantification of metabolites found in human sebum. Sebum is a lipid-rich oily substance secreted by the sebaceous glands onto the skin surface for skin homeostasis, lubrication, thermoregulation, and environmental protection. Interest in sebomics has grown over the last decade due to its potential for rapid analysis following non-invasive sampling for a range of clinical and environmental applications. OBJECTIVES To provide an overview of various sebum sampling techniques with their associated challenges. To evaluate applications of sebum for clinical research, drug monitoring, and human biomonitoring. To provide a commentary of the opportunities of using sebum as a diagnostic biofluid in the future. METHODS Bibliometric analyses of selected keywords regarding skin surface analysis using the Scopus search engine from 1960 to 2022 was performed on 12th January 2023. The published literature was compartmentalised based on what the work contributed to in the following areas: the understanding about sebum, its composition, the analytical technologies used, or the purpose of use of sebum. The findings were summarised in this review. RESULTS Historically, about 15 methods of sampling have been used for sebum collection. The sample preparation approaches vary depending on the analytes of interest and are summarised. The use of sebum is not limited to just skin diseases or drug monitoring but also demonstrated for other systemic disease. Most of the work carried out for untargeted analysis of metabolites associated with sebum has been in the recent two decades. CONCLUSION Sebum has a huge potential beyond skin research and understanding how one's physiological state affects or reflects on the skin metabolome via the sebaceous glands itself or by interactions with sebaceous secretion, will open doors for simpler biomonitoring. Sebum acts as a sink to environmental metabolites and has applications awaiting to be explored, such as biosecurity, cross-border migration, localised exposure to harmful substances, and high-throughput population screening. These applications will be possible with rapid advances in volatile headspace and lipidomics method development as well as the ability of the metabolomics community to annotate unknown species better. A key issue with skin surface analysis that remains unsolved is attributing the source of the metabolites found on the skin surface before meaningful biological interpretation.

Abstract
BACKGROUND Botulinum toxin type A (BoNT-A) can not only reduce the dynamic wrinkles but also improve the skin quality. This study aims to quantitaively and comprehensively assess the improvement of dynamic wrinkles and skin quality following BoNT-A treatment on the upper face. METHODS Patients were recruited to receive BoNT-A treatment of the glabellar, frontal, and lateral periorbital wrinkles. Antera 3D camera was used to evaluate the skin quality and dynamic wrinkle severity. Follow-up visits were at 1 week, 1 month, 3 months, and 6 months after treatment. Different filters were utilized to quantitatively detect the severity of fine wrinkles (FWS), the volume of pores (PV), the roughness of skin texture (STR), and the severity of dynamic wrinkles (DWS). RESULTS Twenty-four participants (average 30.5 ± 7.2 years) were recruited. The significant improvement of PV, FWS, and STR in different areas usually maintained from 1 to 6 months after injections but of DWS only existed within 3 months. For each area, the improvement rates of FWS, PV, and STR peaked at 3 months or 6 months after treatment while the maximal improvement of DWS was observed at 1 month posttreatment. CONCLUSION After BoNT-A treatment for dynamic wrinkles on the upper face, the skin quality of target regions can also be ameliorated. The improvement of skin quality and dynamic wrinkles presented unparallel patterns. The former is with a slower onset but longer duration while the latter exhibits a more rapid onset but shorter duration.

Abstract
Purpose Everyone pursues perfect skin, but there exist significant differences between cultures, and no commonly accepted standards have been established. Therefore, our study attempted to define the "ideal skin" of oriental women and analyze the relationship between different skin physiological parameters and microbiomes. Patients and Methods Based on our customized grading standard, the VISIA CR photos of 111 young women aged from 18 to 25 in Shanghai were collected and scored by the severity of pores, acne, spots, and wrinkles. The volunteers were then divided into "ideal skin" (W1), "normal skin" (W2), and "undesirable skin" (W3) groups. The physiological parameters of facial skin were measured by non-invasive instrumental methods, and the skin microbiome was analyzed by 16S rRNA and ITS high-throughput sequencing. Results From "ideal skin" to "undesirable skin", the skin physiological parameters, α-diversity, and composition of the facial microbiome showed noticeable regular changes. Compared with the "normal skin" (W2) and "undesirable skin" (W3), the "ideal skin" (W1) group had lower sebum content, TEWL, melanin, hemoglobin, and roughness but higher hydration content and skin pH value. Furthermore, the Shannon index of skin bacteria was significantly increased in W1 (P = 0.004), suggesting that the ideal skin had higher species diversity. From W1 to W3, the species composition was changed significantly. The abundance of Actinobacteria was increased, while Proteobacteria and Bacteroidetes were decreased. Correspondingly, the abundances of lipophilic Propionibacterium and Malassezia were increased, while the abundances of Stenotrophomonas, Pseudomonas, Ralstonia, and Streptococcus, were significantly decreased. Additionally, Spearman correlation analysis revealed strong correlations between the physiological parameters and the microbiota. Notably, the Shannon index of skin bacteria was significantly positively correlated with skin hydration (P = 0.03) but negatively correlated with the abundance of Cutibacterium (P = 0.000), hemoglobin content (P = 0.025), and sebum content (P = 0.5). Therefore, the skin hydration content and the abundance of Cutibacterium played an important role in maintaining the α-diversity and skin homeostasis. Conclusion Ideal skin had better water-oil balance and barrier function, higher microbial diversity, and more reasonable species distribution. Therefore, daily skincare needs to control skin oil and maintain skin microecological balance to achieve ideal skin conditions for young women aged 18-25 years old.

Abstract
Treatment of an infected shoulder prosthesis differs significantly from other joint infections because of the unique microbiome, dominated by Cutibacterium acnes. The cause of an infection, its time of onset, the bacterial spectrum and comorbidities have to be considered for evaluation and treatment. The diagnostic workup is sometimes complex, and the recognition of a chronic and low-grade infection is often difficult because typical clinical and laboratory markers may be normal. Treatment is surgical; the therapeutic spectrum ranges from arthroscopic irrigation and open debridement with the exchange of components to one- and two-stage revisions using antibiotic-loaded spacers. Early detection and a targeted, appropriate therapy are crucial to avoid extensive soft tissue and bone damage.

Abstract
BACKGROUND Cutibacterium Acnes (C.acnes) has been linked to several shoulder pathologies. An alternative hypothesis suggests it only occurs in the joint secondary to previous instrumentation. Our hypothesis was patients with previous instrumentation would have C.acnes in their joint if it was in skin. MATERIALS AND METHODS Sixty-six patients undergoing arthroscopic shoulder surgery had biopsies taken from the affected joint at the time of surgery, along with control biopsies of subdermal fat. The extended culture results were assessed and correlated to previous intervention. RESULTS 35% tested positive for C.acnes in their joint. 78% were male. 53% had absence of C.acnes in both skin and joint and 29% had presence in both (p = 0.0001). 15% with previous surgery had C.acnes. 53% with previous injection had C.acnes. 25% of patients with virgin joints had C.acnes. There was no statistical difference in the presence of C.acnes in the joint between those with previous instrumentation and without. CONCLUSION The significant factors for joint C.acnes were male sex and the presence of the bacteria in the fat. Previous instrumentation was not correlated with C.acnes in the joint. This raises the question of whether the process of biopsy itself may lead to inoculation of the joint.

[PMID: 36038248 DOI: 10.1111/jocd.15339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 08/10/2022] [Accepted: 08/26/2022] [Indexed: 01/06/2023]
Abstract
OBJECTIVE This study aimed to analyze the clinical results and influencing factors of the fractional microneedle radiofrequency (FMR) treatment for enlarged facial pores on different facial sites. METHODS The clinical data of patients with enlarged facial pores who underwent FMR treatment from January 2019 to December 2020 were collected. The efficacy and complications of FMR for enlarged pores in different facial areas were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to explore the clinical factors related to the efficacy of FMR after the first treatment session. RESULTS Totally, 75 patients with enlarged facial pores were included (full-face FMR for 45, nasal FMR for 58, frontal FMR for 45, and cheek FMR for 72 patients). All patients received more than one treatment session, two patients received five treatment sessions, and the mean number of FMR session was 1.7. The moderate to excellent improvement rates in patients with nasal, frontal and cheek enlarged pores after the first session were 13.8%, 8.9%, and 11.1%, respectively. The improvement rate rose with the increasing number of treatment sessions. Multivariate logistic regression analysis revealed that long pulse-width (300 ms) was positively associated with clinical efficacy after the first session (OR = 22.4, 95% CI [2.0-250.4], p = 0.012), compared with the short pulse-width group (100-200 ms). The main adverse effects after FMR were transient pain, erythema, and edema. A minority of patients developed acneiform eruption. CONCLUSION This study confirms that FMR is safe and effective in improving enlarged facial pores. The pulse width is associated with the improvement of nasal enlarged pores.

Abstract
BACKGROUND Worldwide, grapes (Vitis vinifera L.; family: Vitaceae) are one of the most important fruits. Grapeseed oil is rich in bioactive constituents that could be beneficial to the health and aesthetic features of human skin. OBJECTIVE This study was conducted to evaluate the effects of a novel grapeseed oil-loaded dermocosmetic nanoemulgel on biophysical parameters of facial skin. METHODS This was a split-face, blinded, placebo-controlled study. A novel grapeseed oil-loaded dermocosmetic nanoemulgel was developed, and its effects on the biophysical parameters of the facial skin were evaluated and compared to those of a placebo formulation on the cheeks of 15 healthy volunteers. Melanin, erythema, sebum production, fine and large facial pores, moisture, and elasticity levels were measured using Mexameter®, Corneometer®, Sebumeter®, Cutometer®, and VisioFace®. Measurements were made on weekly basis for 12 weeks. RESULTS Compared to the placebo, the novel grapeseed oil-loaded dermocosmetic nanoemulgel received significantly higher sensory scores with regard to appearance, color, odor, consistency, adhesion, sensation, cohesiveness, and spreadability (p-value < 0.05). Additionally, the novel nanoemulgel continuously and significantly reduced skin melanin, erythema, sebum production, and fine and large pores (p-value < 0.05). On the contrary, the novel nanoemulgel continuously and significantly increased skin moisture contents and elasticity (p-value < 0.05). CONCLUSION The novel grapeseed oil-loaded dermocosmetic nanoemulgel had attractive cosmetic attributes that could be useful for improving imperfections of the human skin. Future studies are still needed to test and evaluate the benefits of this novel grapeseed oil-loaded dermocosmetic nanoemulgel in disease conditions.

Abstract
BACKGROUND People whose skin type is oily have experienced an esthetic and hygienic discomfort due to the excessive secretion of the sebum during the day and night time, and therefore sebum control is required. In this study, we aimed to find out whether the skin status between the oily and nonoily skin indicates a significant difference before and after sleep. MATERIALS AND METHODS Forty Korean males and females whose skin type was oily or nonoily participated in this study. To investigate the difference of the skin between oily and nonoily skin before and after sleep, we measured the sebum, skin pore, texture, and redness on their cheek at baseline and after 4-h sleep. Moreover, the significant level was determined at p < 0.05. RESULTS Parameters of sebum and skin pore significantly increased after 4-h sleep compared with baseline in the oily and nonoily skin (p < 0.05). Moreover, the increment of sebum and pore parameters in the oily skin was significantly higher than those in the nonoily skin (p < 0.05). In the case of skin texture and redness, parameters of them were significantly changed after 4-h sleep compared with baseline only in the oily skin (p < 0.05), and there was no significant difference among groups. CONCLUSIONS We found that the change rates of the sebum secretion and skin pore in oily skin were significantly higher than those in nonoily skin after 4-h sleep. These results suggest the necessity of the skin care depending on the skin type before sleeping.

Botulinum Neurotoxin Type A Directly Affects Sebocytes and Modulates Oleic Acid-Induced Lipogenesis. Toxins (Basel) 2022; 14:toxins14100708.

Abstract
Excess sebum (seborrhea) results in oily skin and is associated with large pore size and acne. Studies in healthy, seborrheic volunteers have reported that intradermal injection of commercial preparations of botulinum neurotoxin type A (BoNT/A) (onabotulinumtoxinA, abobotulinumtoxinA, and incobotulinumtoxinA) reduced sebum production, and thus, skin oiliness and pore size. The mechanism for these effects has not been fully elucidated; however, several theories involving direct or indirect effects of BoNT/A on neuronal and/or dermal cells (e.g., sebocytes) have been proposed. In the present study, we evaluated the direct effect of native research grade BoNT/A complex, a commercial preparation of BoNT/A (onabotA), and BoNT/A variants on sebocyte lipogenesis using an in vitro sebocyte cell model. We show that picomolar concentrations of BoNT/A (BoNT/A complex: half maximal effective concentration [EC50] = 24 pM; BoNT/A 150 kDa: EC50 = 34 pM) modulate sebocyte lipogenesis and reduce oleic acid-induced sebocyte differentiation, lipogenesis, and holocrine-like secretion. Comparative studies with the binding domain of BoNT/A, which lacks enzymatic activity, show that this effect is independent of the enzymatic activity of BoNT/A and likely occurs via sebocyte cell surface receptors (e.g., fibroblast growth factor receptors). Overall, these results shed light on the potential mechanism of action and rationale for use of BoNT/A for treatment of sebum-related conditions.

Abstract
BACKGROUND AND OBJECTIVES Transdermally delivered gold nanoparticles (AuNPs) irradiated with near-infrared laser energy can create a photothermal effect within the sebaceous glands (SGs). Photothermal therapy (PTT) can be used clinically to reverse photoaging in SG-rich areas of the skin. Improvements in wrinkles and enlarged pores in Asian skin were assessed following AuNP-mediated PTT with a long-pulsed 755-nm alexandrite laser. STUDY DESIGN/MATERIALS AND METHODS A single-arm, prospective trial was designed. Twenty Korean patients underwent three gold PTT interventions performed 4 weeks apart at laser hair-removal settings without cooling. At Week 20, changes in the wrinkle index (WI) and pore index (PI), size, and count were calculated using three-dimensional camera analyses. Overall improvements in wrinkles and pores (0-4 scale) were assessed by blinded investigators using standardized photographic comparisons. The subjects scored their satisfaction (0-10 scale) and treatment discomfort (0-10 scale). Safety data were also collected. RESULTS There were significant reductions in the WI (8.3%, p < 0.01), pore size (23.1%, p = 0.035), and PI (19.9%, p = 0.034) in the periorbital areas at week 20 compared with baseline. The mean reductions in the size (22.5%, p = 0.027), count (16.5%, p = 0.048), and index (22.4%, p = 0.023) of the cheek pores were also significant. Investigators reported average scores of 3.2 ± 0.6 for improved wrinkle appearance, and 3.1 ± 0.7 for improvement in visible pores. Participants were moderately satisfied with the overall results (7.6 ± 1.8). Subjects felt moderate discomfort during treatment (4.7 ± 2.6). No serious or persistent adverse events occurred. CONCLUSIONS AuNP-mediated PTT showed noticeable efficacy and tolerability in treating wrinkles and pores in Asian skin over a 12 week-follow-up. Further studies with a longer follow-up are needed to confirm the reduction in SG activity at the parameters used.

Abstract
A picosecond-domain laser reportedly elicits positive treatment outcomes for acne scar and enlarged pores, but multiple sessions are often required. We sought to evaluate the efficacy of one-session fractional picosecond 1064-nm laser in treating atrophic acne scar and conspicuous pores. Fifty-nine acne scar patients with skin phototypes III and IV were treated with picosecond 1064-nm laser with microlens array (MLA) (8 mm spot, 0.8 J/cm2, 10 Hz) for one session. The efficacy of acne scar was evaluated by Antera® 3D CS, whereas facial pore counts and diameter were evaluated by VISIA-CR and dermoscopic images, respectively. All measurements were performed at baseline, weeks 1, 2, 4 and 6. Acne scar volume and facial pore counts showed a statistically significant reduction at 1 week and subsequent follow-up period when compared to baseline (weeks 1-6; P < .001). The volume of acne scars and the number of enlarge pores decreased by 22.03% and 15.13%, respectively. Of note, there was no significant change in diameter of facial pores. The adverse events, including erythema and folliculitis, were mild and short-lived. A single session of picosecond 1064-nm laser with MLA was safe and effective in improving atrophic acne scar and the number of enlarged pores.

Abstract
Oily skin from overactive sebaceous glands affects self-confidence and personality. There is report of an association between steroid 5-alpha reductase gene (SRD5A) expression and facial sebum production. There is no study of the effect of Asparagus racemosus Willd. root extract on the regulation of SRD5A mRNA expression and anti-sebum efficacy. This study extracted A. racemosus using the supercritical carbon dioxide fluid technique with ethanol and investigated its biological compounds and activities. The A. racemosus root extract had a high content of polyphenolic compounds, including quercetin, naringenin, and p-coumaric acid, and DPPH scavenging activity comparable to that of the standard L-ascorbic acid. A. racemosus root extract showed not only a significant reduction in SRD5A1 and SRD5A2 mRNA expression by about 45.45% and 90.86%, respectively, but also a reduction in the in vivo anti-sebum efficacy in male volunteers, with significantly superior percentage changes in facial sebum production and a reduction in the percentages of pore area after 15 and 30 days of treatment. It can be concluded that A. racemosus root extract with a high content of polyphenol compounds, great antioxidant effects, promising downregulation of SRD5A1 and SRD5A2, and predominant facial sebum reduction and pore-minimizing efficacy could be a candidate for an anti-sebum and pore-minimizing active ingredient to serve in functional cosmetic applications.

Abstract
Intradermal injection of botulinum neurotoxin is a frequently performed procedure in aesthetic dermatology to improve facial skin tone, texture, fine wrinkles, and enlarged pores. In practice, botulinum neurotoxin type A is also used to reduce skin oiliness of the face. There is increasing evidence that acetylcholine plays specific roles in sebum production, suggesting that botulinum neurotoxin type A may reduce sebum production by interfering with cholinergic transmission between sebaceous glands and autonomic nerve terminals. Botulinum neurotoxins can also inhibit several pathogenetic components of acne development, suggesting that botulinum neurotoxins can be used as a safe and effective treatment modality for acne and other skin disorders related to overactivity of sebaceous glands. This review aims to explore the current evidence behind the treatment of facial seborrhea and acne with botulinum neurotoxin type A.

Abstract
Botulinum toxin A (BTX-A) injections have become the most popular noninvasive cosmetic procedures performed worldwide. With growing interest, investigators continue to uncover an expanding array of aesthetic indications for BTX-A. Botulinum toxin A has been used off-label in the management of masseter hypertrophy for facial slimming, platysmal bands, nasal 'bunny' lines, perioral rhytides, gummy smile and scars, to name a few. Interestingly, the injection of multiple microdroplets of dilute BTX-A into the dermis, sometimes referred to as 'microbotox', has been investigated as a tool for facial rejuvenation. A handful of prospective studies and case series have demonstrated the benefit of BTX-A in the treatment of facial erythema and improving skin texture. The aim of this review is to summarize and appraise currently available data on the role of BTX-A in treating facial erythema and skin quality, with a special focus on potential pathophysiologic mechanisms.

Abstract
Background Skin pores are structural features of the skin, which tend to change as the skin ages. Since previous studies measured pores two‐dimensionally, precise measurements using three‐dimensional imaging were needed to comprehensively understand skin pores. This study aimed to determine the patterns behind the changes in skin pores during one's lifetime and to identify new characteristics of the pores in aged. Materials and Methods Skin surface profiles were measured three‐dimensionally from the cheeks of 101 Korean women from February to March 2020 to analyze the exact state of their pores. The researchers performed K‐means clustering to classify the skin pores, and topographical features of pores were analyzed as well. Statistical analyses were performed to verify the differences in the skin pore characteristics among clusters and the correlation between clusters and ages. Results Skin pores were classified into five groups based on size, density, and elongation. The skin conditions of the cluster groups were well correlated with aging, despite excluding age as a factor in pore classification. Adjacent skin pores tend to connect in the elderly. Conclusion Skin pores become larger and longer over time. Skin pores connect together in the elderly, which might be related to wrinkle formation. This phenomenon strongly suggests skin pores as a characteristic of aging skin and as a potential target for anti‐aging treatment.

Abstract
BACKGROUND Flawless skin is one of the most universally desired features, and demand for improvements in skin quality is growing rapidly. Skin quality has been shown to substantially impact emotional health, quality of life, self-perception, and interactions with others. Although skin quality improvements are a common end point in studies of cosmeceuticals, they are rarely assessed in clinical studies of other aesthetic treatments and products. Descriptive terminology for skin quality parameters also varies considerably within the aesthetic field, relying on a range of redundant and occasionally contradictory descriptors. In short, skin quality has not been clearly defined. OBJECTIVE The goal of this review is to highlight the importance of skin quality to patients and physicians, explore known and unknown factors comprising skin quality, and provide clarity regarding terminology, descriptors, and evaluation tools for assessing skin quality. MATERIALS AND METHODS A review of the literature on skin quality was performed without limitation on publication date. Relevant articles are presented. RESULTS AND CONCLUSION We propose a framework of attributes contributing to skin quality rooted in 3 fundamental categories-visible, mechanical, and topographical-with the aim to provide information to help guide clinicians and inform future clinical studies.

Abstract
BACKGROUND This study aimed to examine the effectiveness of botulinum toxin type A (BTX-A) in the treatment of acne. METHODS The study was conducted in 2018 on 12 patients, 10 females and two males, aged 35 years on average. The injections with BTX-A were given during 2 weeks into the face skin in a dosage of 0.125-0.250 units. RESULTS Skin moisture indexes increased during the therapy by 4% (P ≤ 0.05), and porosity decreased by 7% (P ≤ 0.01). Maximal changes were recorded for the sulci and pigmentation of the skin, namely, its values decreased by 10 and 9%, respectively (P ≤ 0.01). BTX-A is recommended for an application not only in plastic surgeries but also for local correction of acne on the patient's skin. CONCLUSION A positive correlation was revealed between the duration of treatment and reduction of skin oiliness (0.87), pigmentation (0.78), skin sulci (0.84), and skin porosity (0.88), and negative correlation was established with increased skin moisture (-0.64). The obtained dependencies apply for the therapy period of up to 2 weeks. Pharmacological properties of BTX-A allow recommending it as a drug used in post-acne therapy.

Abstract
BACKGROUND Microbotulinum refers to the systematic injection of tiny blebs of diluted botulinum toxin at repeated intervals into the skin. This targets the superficial fibers of the facial muscles, and weakens their insertion into the undersurface of the skin, which is responsible for the fine lines and wrinkles on the face. The authors present a pilot study based on quantitative evaluation, by means of a skin-scanning technology, of the aesthetic improvement of skin texture, microroughness, and enlarged pore size in a patient group treated with microbotulinum injections for cosmetic purposes. METHODS The treatment was performed using a 32-gauge needle to deliver injections on a regular 1-cm grid from the forehead to the cheek and down to the jawline. RESULTS Sixty of the 62 patients completed the study. All analyzed parameters improved significantly (p < 0.0001) at 90 days with respect to the pretreatment time point (skin texture, -1.93 ± 0.51; microroughness, -2.48 ± 0.79; and pore diameter, 2.1 ± 0.43). Best results have been obtained in patients aged between 42.7 and 46.8 years, and standard deviation calculation allows us to recommend it in patients aged between 36.5 and 53 years. CONCLUSIONS The results of this pilot study suggest that intradermal botulinum toxin injection, or so-called microbotulinum, is a safe and effective method to treat skin flaws. Because of the high satisfaction rate among both physicians and patients, further studies are indeed mandatory to determine the optimal number of units needed for a longer and lasting effect with this particular novel dilution. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND Many factors relate to enlargement and visibility of facial pores. However, how enlargement relates to modification of the skin structure is still poorly analysed. Therefore, our aim was to characterise the visible features and the micro-environment of facial pores. MATERIALS AND METHODS We recruited 160 women, half of them with normal-size facial pores, the other half presenting enlarged pores. We analysed their right cheek using standardised photography, in vivo reflectance microscopy and optical coherence tomography. RESULTS If the area of pores is indeed the most differentiating visible characteristic, enlarged facial pores are also denser and more contrasted. At the structural level, enlarged facial pores present a more regular organisation of keratinocytes, an irregular dermo-epidermal junction and a higher attenuation of collagen between the surface and deeper layers. Still, the most relevant alterations of enlarged facial pores are the presence of bright tubular structures surrounding hair follicles and enlarged hair shafts. CONCLUSION These observations suggest that alterations of the stroma could result in altered skin tensions, leading to the dilation of the infundibulum and enlarged hair shaft. The modified tension would also explain the more regular organisation of the keratinocytes and the irregular dermo-epidermal junction.

Abstract
BACKGROUND AND OBJECTIVES Enlarged pores are one of the most common causes of skin surface irregularities. Existing studies supporting the benefit of lasers and energy-based devices (EBD) for this condition are limited, with a short duration of follow-up period. We aimed to evaluate the efficacy and adverse effects of Er:YAG laser for treatment of enlarged pores in dark-skinned patients. STUDY DESIGN/MATERIALS AND METHODS Nineteen subjects (aged 26-47 years) with skin phototypes III (21.1%) and IV (78.9%) and enlarged pores were treated with 4 monthly sessions of Erbium:YAG laser. Objective (ultraviolet light A video camera) and subjective (clinical evaluation by two blinded dermatologists) assessments were obtained at baseline, 1-month after each treatment and at 1, 3, and 6 months after the final treatment. RESULTS The weighted mean score of quartile grading scales showed significant improvement in pore size from baseline starting at 1-month after the third treatment and continued until 3 months after the fourth (final) treatment (P < 0.001). However, the improvement dropped significantly at 6 months after the final treatment. Objective measurements of the improvements in skin surface smoothness and wrinkles corresponded with the physician raters' clinical evaluation. CONCLUSIONS Erbium:YAG laser is a safe and effective treatment for enlarged pores in dark-skinned individuals. Maintenance treatments are recommended to achieve a longer-lasting outcome. Lasers Surg.

Abstract
Facial pore enlargement is considered a significant esthetic and health concern in skincare cosmetics. The pores fulfill the critical function of keeping the skin surface hydrated and protected against microbial infections. The hyperseborrhea, the stress factors, and the hormonal triggers can cause pore size enlargement, causing higher susceptibility of the skin to microbe aggressions and inflammatory reactions. Thus, reducing excessive sebum production and keeping functional pores are two of the most requested activities in skincare cosmetics. A Cirsium eriophorum cell culture extract was investigated for its role in sebum regulation, stratum corneum desquamation, and anti-inflammation. The extract was able to regulate essential markers associated with sebum secretion and pore enlargements, such as the enzyme 5α-reductase, which plays a central role in sebum production, and the trypsin-like serine protease Kallikrein 5, which promotes skin exfoliation and antimicrobial response. Moreover, the extract showed a sebum-normalizing and pore refining activity in individuals having seborrheic or acne-prone skins, suggesting a role of the C. eriophorum extract in rebalancing altered skin conditions responsible for pore enlargement.

Abstract
BACKGROUND Phenolic and flavonoid compounds found in plants alleviate the photo-damaging skin conditions by playing a major role in skin rejuvenation. AIMS The aim of the study was to explore the cosmeceutical effects of Cinnamomum tamala extract. OBJECTIVE Recent research was aimed to quantify phenols and flavonoids in the natural extract of C tamala leaves, to develop its phyto-cosmetic emulgel and to assess effects of emulgel on healthy human skin. METHOD Phenols and flavonoids in C tamala (CT) extract were quantified by using ELISA assay. Emulgel formulation loaded with 4% C tamala (CT emulgel) was developed, and its cosmetic effects were evaluated on the cheeks of 13 healthy female test volunteers by comparing with placebo (base). Facial parameters including melanin, erythema, sebum, and visible facial pores (size and area) were studied by using Mexameter® , Sebumeter® , and VisioFace® at regular interval for 90 days. RESULTS Total phenolic content and total flavonoids content of C tamala leaves extract were found to be 73.08 ± 0.0078 mg GAE/g and 52.63 ± 0.0060 mg QE/g CT extract respectively. As compared to placebo (base), CT emulgel was found to be significantly (P ≤ .05) effective in minimizing skin photo-damaging effects by reducing the levels of melanin, erythema, and sebum and size and count of both fine and large facial pores. CONCLUSION Cinnamomum tamala leaves extract, being a rich source of phenols and flavonoids minimized the photo-damaging effects by reducing skin melanin, erythema, and excess sebum; improving the skin imperfections by reducing facial pore count and area as assessed by advanced imaging and bioengineering techniques.

Abstract
BACKGROUND Subjective facial skin type is most frequently determined by the amount of sebum, which showed trends across subjective skin types in most previous studies while not in some. This study was conducted to evaluate the associations among subjective skin type, amount of sebum, stratum corneum hydration, and pore size in Thai women. METHODS Sixty-two healthy women with either self-described subjective oily or dry skin type were included and casual sebum level (CSL), sebum excretion rate (SER), clinical pore size score, mean pore area, and stratum corneum hydration were measured at several facial sites. Correlation coefficients between amount of sebum and other parameters were estimated. RESULTS Casual sebum level and sebum excretion rate were significantly higher in oily-skinned than dry-skinned group by 1.6-2.1 times. Mean pore area and clinical pore size score were not different between the 2 groups, nor did they correlate with CSL or SER. Corneometry was shown to be significantly higher in dry-skinned than oily-skinned group. Significant, negative correlations between corneometry and CSL were also found. CONCLUSION The subjective facial skin types were consistent with the amount of sebum, but not pore size or corneometry, among Thai women.

Abstract
Introduction The skin is important for the perception of health and beauty. Knowledge of the physiological, chemical, and biophysical differences between the skin of male and female patients helps dermatologists develop a proper approach not only for the management of skin diseases but also to properly take care of cosmetic issues. The influence of genetic and environmental factors on skin characteristics is also critical to consider. Methods A literature search of PubMed and Google was conducted to compare the biophysical and biomechanical properties of the skin of male and female patients using the keywords "skin", "hydration", "water loss", "sebum", "circulation", "color", "thickness", "elasticity", "pH", "friction", "wrinkle", "sex", "male", and "female". Results A total of 1070 titles were found. After removing duplications and non-English papers, the number was reduced to 632. Of the 632 titles, 57 were deemed suitable for inclusion in this review. The studies show that the skin parameters of hydration, transepidermal water loss, sebum, microcirculation, pigmentation, and thickness are generally higher in men but skin pH is higher in women. Conclusions These parameters can be considered as age markers in some cases and are susceptible to change according to environment and life style. Biometrological studies of the skin provide useful information in the selection of active principles and other ingredients of formulations to develop a specific approach for cosmetic treatments.

Cizauskaite U, Bernatoniene J. Innovative Natural Ingredients-Based Multiple Emulsions: The Effect on Human Skin Moisture, Sebum Content, Pore Size and Pigmentation. Molecules 2018; 23:molecules23061428. [PMID: 29895799 PMCID: PMC6100419 DOI: 10.3390/molecules23061428] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 06/07/2018] [Accepted: 06/11/2018] [Indexed: 11/16/2022] Open
Abstract
The increased interest in natural cosmetics has resulted in a higher market demand for preservative-free products based on herbal ingredients. An innovative W/O/W type emulsions containing herbal extracts were prepared directly; its cation form was induced by an ethanolic rosemary extract and stabilized using weak herbal gels. Due to the wide phytochemical composition of herbal extracts and the presence of alcohol in the emulsion system, which can cause skin irritation, sensitization or dryness when applied topically, the safety of the investigated drug delivery system is necessary. The aim of our study was to estimate the potential of W/O/W emulsions based on natural ingredients for skin irritation and phototoxicity using reconstructed 3D epidermis models in vitro and to evaluate in vivo its effect on human skin moisture, sebum content and pigmentation by biomedical examination using a dermatoscopic camera and corneometer. According to the results obtained after in vitro cell viability test the investigated emulsion was neither irritant nor phototoxic to human skin keratinocytes. W/O/W emulsion did not cause skin dryness in vivo, despite the fact that it contained ethanol. We can conclude that the emulsion is safe for use as a leave-on product due to the positive effect on human skin characteristics or as a semisolid pharmaceutical base where active compounds could be encapsulated.

Abstract
Individual responses of human skin to the environmental stress are determined by differences in the anatomy and physiology that are closely linked to the genetic characteristics such as pigmentation. Ethnic skin phenotypes can be distinguished based on defined genotypic traits, structural organization and compartmentalized sensitivity to distinct extrinsic aging factors. These differences are not only responsible for the variation in skin performance after exposure to damaging conditions, but can also affect the mechanisms of drug absorption, sensitization and other longer term effects. The unique characteristics of the individual skin function and, particularly, of the ethnic skin type are currently considered to shape the future of clinical and pharmacologic interventions as a basis for personalized skincare. Individual approaches to skincare render a novel and actively growing area with a range of biomedical and commercial applications within cosmetics industry. In this review, we summarize the aspects of the molecular and clinical manifestations of the environmental stress on human skin and proposed protective mechanisms that are linked to ethnic differences and pathophysiology of extrinsic skin aging. We subsequently discuss the possible applications and translation of this knowledge into personalized skincare.

Abstract
BACKGROUND/AIMS Ethnic skin types are known to differ in their morphological and physiological features. Thus, treatment responses may vary among different races. We aimed to assess skin morphology of different ethnicities and to compare the effect of short-term moisturizer application using optical coherence tomography (OCT) and reflectance confocal microscopy (RCM). METHODS Thirty healthy female subjects of European, Asian and Black ethnicity at 30-45 years of age were included in the study. OCT and RCM imaging was performed on the cheek to compare morphology. Following the 2-week application of a moisturizer cream (Sebamed® lotion) on one forearm, imaging was performed on both forearms to assess and compare treatment responses. RESULTS Epidermal thickness and morphology of pores varied between the three ethnic groups, with Black subjects displaying the thickest epidermis and largest skin pores. On the treated forearm, OCT measurements revealed a significantly thicker epidermis in all groups as compared to the untreated forearm. Width of skin folds on the treated forearm was measured by RCM to be significantly lower in all ethnic groups as compared to the untreated forearm. CONCLUSION Different ethnic skin types showed variations in skin morphology and treatment response to short-term moisturizer application. OCT and RCM were useful methods for noninvasive, real-time, repeated assessment of ethnic skin.

Abstract
BACKGROUND Increasing the number of enlarged pores causes cosmetic problems. The difference in the number of enlarged pores according to facial site, age, and sex is unclear. OBJECTIVE To analyze the distribution of the number of enlarged pores according to facial site, age, and sex. METHODS AND MATERIALS We analyzed the number of the enlarged pores and the percentage of wrinkles in the nose, forehead, and cheek from 434 polarized images. The measurement results were analyzed according to site, age, and sex. Relationship between enlarged pore counts and wrinkle severity was also analyzed. The study was conducted by using DermaVision,™ which can take cross-polarization, parallel polarization, and ultraviolet light images. RESULTS The enlarged pores of the nose and forehead were more prominent than in the cheeks. Pore counts were increased with age, and the increment was significant between the 30's and 40's. There was no significant difference by gender. Enlarged pore counts were related to wrinkle severity. CONCLUSIONS The number of enlarged pores differs depending on body site and increased with age. The enlarged pore counts correlate with wrinkle severity and the correlation varies depending on the body site.

Abstract
BACKGROUND Skin imaging analysis, acting as a supplement to noninvasive bioengineering devices, has been widely used in medical cosmetology and cosmetic product evaluation. The main aim of this study is to assess the differences and correlations in measuring skin spots, wrinkles, vascular features, porphyrin, and pore between two commercially available image analysis software. MATERIALS AND METHODS Seventy healthy women were included in the study. Before taking pictures, the dermatologist evaluated subjects' skin conditions. Test sites included the forehead, cheek, and periorbital skin. A 2 × 2 cm cardboard was used to make a mark on the skin surface. Pictures were taken using VISIA® under three kinds light conditions and analyzed using VISIA® and IPP® respectively. RESULTS (1) Skin pore, red area, ultraviolet spot, brown spot, porphyrin, and wrinkle measured with VISIA® were correlated with those measured with IPP® (P < .01). (2) Spot, wrinkle, fine line, brown spot, and red area analyzed with VISIA® were correlated with age on the forehead and periorbital skin (P < .05). L-value, Crow's feet, ultraviolet spot, brown spot, and red area analyzed with IPP® were correlated with age on the periorbital skin (P < .05). (3) L-value, spot, wrinkle, fine line, porphyrin, red area, and pore analyzed with VISIA® and IPP® showed correlations with the subjective evaluation scores (P < .05). CONCLUSIONS VISIA® and IPP® showed acceptable correlation in measuring various skin conditions. VISIA® showed a high sensibility when measured on the forehead skin. IPP® is available as an alternative software program to evaluate skin features.

Abstract
BACKGROUND The skin imaging analysis instruments are widely used to record and measure the surface and subsurface skin conditions. The main aim of this study is to reveal the differences and correlations in measuring wrinkle, skin texture, coloration/evenness, vascular features, and pore between two commercially available instruments. METHODS Twenty-eight subjects were enrolled in the study. A 2*2 cm cardboard was used to make sure the two instruments analyze the same area. Pictures were taken and analyzed by the VISIA® from Canfield and the ANTERA 3D® CS from Miravex, in sequence. RESULTS The spot, ultraviolet spot, brown spot, red area, texture values measured with VISIA® were positively correlated with age, while the pore and wrinkle values showed no significance. The wrinkle, texture, melanin, hemoglobin, pore index, pore volume values measured with ANTERA 3D® had a significantly positive correlation with age. The spot, brown spot values from VISIA® were positively correlated with the melanin value from ANTERA 3D® . Texture value measured with the two instruments revealed positive linear correlation. Strong correlation was found between the red area value from VISIA® and the hemoglobin value from ANTERA 3D® . Ultraviolet spot from VISIA® showed no linear correlation with the melanin value from ANTERA 3D® . Neither of the wrinkle and pore measured with the two instruments showed linear correlation. CONCLUSIONS ANTERA 3D® relies on multidirectional illumination obtained by LEDs of different wavelengths from different directions which make it advanced at the qualitative evaluation of various dermatologic conditions. Compared with VISIA® , ANTERA 3D® is more sensitive in the assessment of wrinkle and it may also be available to evaluate the aging-related enlarged pore.

Abstract
BACKGROUND Botulinum toxin is a neurotoxin produced by the bacterium Clostridium botulinum which causes a flaccid muscle paralysis. It is currently used for aesthetic treatments and in the focal hyperhidrosis. Recently, botulinum toxin has also been used experimentally in many other dermatological conditions with good results. OBJECTIVE To review and analyze the possible botulinum toxin off-label applications published. METHODS A retrospective review of the published data was conducted. CONCLUSIONS this potent drug can lead to several off-label indications of interest for dermatologists. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and dose protocols.

Abstract
BACKGROUND Propionibacterium acnes (P acnes) has been linked to chronic infections in shoulder surgery. It was recently observed during first-time shoulder surgery in healthy patients at a rate between 36% and 56%. Male gender and the anterolateral approach were reported risk factors. Because the skin biology greatly differs, we aimed to correlate skin complaints with P acnes-positive intraoperative cultures from different tissue layer samples in patients undergoing shoulder surgery for the first time. METHODS Intraoperative samples (1 skin, 1 superficial, 1 deep tissue, and 1 control sample) from 112 patients (70 men, 42 women; aged 59.2 years) were cultured. The association between the presence of P acnes in the deep or superficial tissue, or both, and 10 items of a validated preoperative questionnaire for skin pathology was explored. RESULTS The cultures were positive for P acnes in 38.4% (n = 43) of the cases. Skin samples were positive for P acnes in 8% (n = 9), superficial samples were positive in 23% (n = 26), and deep samples were positive in 30% (n = 34). Self-reported "loss of hair" was significantly negatively associated with the presence of P acnes in the superficial or deep tissue sample (P = .00028). DISCUSSION Patients who report having "loss of hair" show fewer P acnes-positive cultures in intraoperative tissue samples taken during open shoulder surgery. Whether this subgroup is at a lesser risk for P acnes infections remains to be substantiated. LEVEL OF EVIDENCE Basic Science Study; Microbiology.
