Maintenance of an Acidic Skin Surface with a Novel Zinc Lactobionate Emollient Preparation Improves Skin Barrier Function in Patients with Atopic Dermatitis. Dermatol Ther (Heidelb) 2024; 14:391-408. [PMID: 38175365 PMCID: PMC10891035 DOI: 10.1007/s13555-023-01084-x] [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: 10/31/2023] [Accepted: 12/06/2023] [Indexed: 01/05/2024] Open
Abstract
INTRODUCTION The skin of patients with atopic dermatitis (AD) is characterised by elevated pH. As a central homeostatic regulator, an increased pH accelerates desquamation and suppresses lipid processing, resulting in diminished skin barrier function. The aim of this study was to determine whether a novel zinc lactobionate emollient cream can strengthen the skin barrier by lowering skin surface pH. METHODS A double-blind, forearm-controlled cohort study was undertaken in patients with AD. Participants applied the test cream to one forearm and a vehicle cream to the other (randomised allocation) twice daily for 56 days. Skin surface pH and barrier function (primary outcomes) were assessed at baseline and after 28 days and 56 days of treatment, amongst other tests. RESULTS A total of 23 adults with AD completed the study. During and after treatment, a sustained difference in skin surface pH was observed between areas treated with the test cream and vehicle (4.50 ± 0.38 versus 5.25 ± 0.54, respectively, p < 0.0001). This was associated with significantly reduced transepidermal water loss (TEWL) on the test cream treated areas compared with control (9.71 ± 2.47 versus 11.20 ± 3.62 g/m2/h, p = 0.0005). Improvements in skin barrier integrity, skin sensitivity to sodium lauryl sulphate, skin hydration, and chymotrypsin-like protease activity were all observed at sites treated with the test cream compared with the control. CONCLUSION Maintenance of an acidic skin surface pH and delivery of physiologic lipids are beneficial for skin health and may help improve AD control by reducing sensitivity to irritants and allergens.

[PMID: 38173771 PMCID: PMC10761209 DOI: 10.1093/rb/rbad101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/12/2023] [Accepted: 10/26/2023] [Indexed: 01/05/2024] Open
Abstract
As a superior alternative to sutures, tissue adhesives have been developed significantly in recent years. However, existing tissue adhesives struggle to form fast and stable adhesion between tissue interfaces, bond weakly in wet environments and lack bioactivity. In this study, a degradable and bioactive citrate-based polyurethane adhesive is constructed to achieve rapid and strong tissue adhesion. The hydrophobic layer was created with polycaprolactone to overcome the bonding failure between tissue and adhesion layer in wet environments, which can effectively improve the wet bonding strength. This citrate-based polyurethane adhesive provides rapid, non-invasive, liquid-tight and seamless closure of skin incisions, overcoming the limitations of sutures and commercial tissue adhesives. In addition, it exhibits biocompatibility, biodegradability and hemostatic properties. The degradation product citrate could promote the process of angiogenesis and accelerate wound healing. This study provides a novel approach to the development of a fast-adhering wet tissue adhesive and provides a valuable contribution to the development of polyurethane-based tissue adhesives.

Abstract
Topical delivery has received great attention due to its localized drug delivery, its patient compliance, and its low risk for side effects. Recent developments have focused on studying new drug delivery systems as a strategy for addressing the challenges of current topical treatments. Here we describe the advances on an innovative drug delivery platform called DELOS nanovesicles for topical drug delivery. Previously, the production of DELOS nanovesicles demonstrated potentiality for the topical treatment of complex wounds, achieving well-tolerated liquid dispersions by this route. Here, research efforts have been focused on designing these nanocarriers with the best skin tolerability to be applied even to damaged skin, and on exploring the feasibility of adapting the colloidal dispersions to a more suitable dosage form for topical application. Accordingly, these drug delivery systems have been efficiently evolved to a hydrogel using MethocelTM K4M, presenting proper stability and rheological properties. Further, the integrity of these nanocarriers when being gellified has been confirmed by cryo-transmission electron microscopy and by Förster resonance energy transfer analysis with fluorescent-labeled DELOS nanovesicles, which is a crucial characterization not widely reported in the literature. Additionally, in vitro experiments have shown that recombinant human Epidermal Growth Factor (rhEGF) protein integrated into gellified DELOS nanovesicles exhibits an enhanced bioactivity compared to the liquid form. Therefore, these studies suggest that such a drug delivery system is maintained unaltered when hydrogellified, becoming the DELOS nanovesicles-based hydrogels, an advanced formulation for topical use.

Abstract
Skin is a key aspect of the immune system in the defence against pathogens. Skin pH regulates the activity of enzymes produced both by hosts and by microbes on host skin, thus implicating pH in disease susceptibility. Skin pH varies inter- and intra-specifically and is influenced by a variety of intrinsic and extrinsic variables. Increased skin alkalinity is associated with a predisposition to cutaneous infections in humans and dogs, and inter-specific and inter-individual variation in skin pH is implicated in differential susceptibility to some skin diseases. The cutaneous pH of bats has not been characterized but is postulated to play a role in susceptibility to white-nose syndrome (WNS), a fungal infection that has decimated several Nearctic bat species. We used non-invasive probes to measure the pH of bat flight membranes in five species with differing susceptibility to WNS. Skin pH ranged from 4.67 to 8.59 and varied among bat species, geographic locations, body parts, age classes, sexes and seasons. Wild Eptesicus fuscus were consistently more acidic than wild Myotis lucifugus, Myotis leibii and Perimyotis subflavus. Juvenile bats had more acidic skin than adults during maternity season but did not differ during swarming. Male M. lucifugus were more acidic than females during maternity season, yet this trend reversed during swarming. Bat skin was more acidic in summer compared to winter, a pattern also reported in humans. Skin pH was more acidic in captive than wild E. fuscus, suggesting environmental impacts on skin pH. The pH of roosting substrates affects skin pH in captive bats and may partially explain seasonal patterns in wild bats that use different roost types across seasons. Future research on the influence of pH on microbial pathogenic factors and skin barrier function may provide valuable insights on new therapeutic targets for treating bat skin conditions.

Abstract
BACKGROUND Recently, men's interest and participation in cosmetology have increased, and the number of "grooming" men who are exorbitantly investing in fashion and looks has increased, further increasing the growth potential of men's cosmetics. OBJECTIVES The purpose of this study was to analyze the skin diseases of men in their 20s and 30s in Korea, focusing on the comparison before and after enlistment, and to study the changes in cosmetic use and the difference in cosmetic preference according to the military service problem of Korean men. METHODS We enrolled 450 people, after excluding 50 dishonest respondents. Statistical data processing collected with the data analysis method were analyzed using the Statistical Package for Social Science (SPSS) WIN25.0 statistical package program through data coding and cleaning. RESULTS A total of 217 (48.2%) people preferred the cosmetic type of skin/lotion preferred by the private sector, and the cosmetic type required by the military was a complex skin lotion (48.2%) with 216 people (48.2%). All-in-one products were the most common products. The P-value was P < .001 or more. CONCLUSION The results of this comprehensive study indicated skin problems of Korean military personnel changes in the use of cosmetics and differences in preference according to different characteristics focused on comparison pre- and post-enlistment was assessed.

Abstract
BACKGROUND Ablative fractional carbon dioxide laser (AFCO2) resurfacing causes transient skin barrier disruption characterized by decreased skin hydration and increased transepidermal water loss (TEWL). Snail Soothing and Repairing (SSR) cream, containing several glycoproteins with potential antimicrobial and antioxidant effects, may benefit skin hydration promotion after the laser treatment. OBJECTIVE To evaluate the efficacy and safety of SSR cream in skin hydration promotion after AFCO2 resurfacing. METHOD The study was a double-blinded, split-face, placebo-controlled trial in participants aged 18-50 years with atrophic acne scars on both cheeks. After AFCO2 resurfacing, participants applied the product or placebo on either cheek twice daily for 14 days. Corneometry, TEWL, colorimetry, and clinical assessments (edema, erythema, crusting, pruritus, and tightness score) were evaluated at baseline, day 7, and day 14 after AFCO2 resurfacing. RESULTS From 22 participants in the study, the SSR cream-treated sides showed significantly higher corneometry levels than placebo-treated sides at day 14 (p = 0.033), while TEWL and colorimetry levels were not different at any study visits. Pruritus and tightness scores of the SSR side were lower, but not significant, than the placebo. Other clinical assessments (edema, erythema, and crusting) showed similar results. No significant adverse events took place. CONCLUSION The SSR cream significantly improved skin hydration, highlighting skin barrier restoration after AFCO2 resurfacing, with a good safety profile.
