Abstract
Background As a keratolytic, salicylic acid (SA) can be topically applied in various formulations and doses in dermatology. Supramolecular SA hydrogel, a new SA formulation with higher bioavailability, is developed and commercially available nowadays. However, there still remain concerns that the long-term and continual application of SA at low concentrations may jeopardize the cutaneous barrier properties. Aim of the Study To reveal the long-term effects of 0.5-5% supramolecular SA hydrogel on the skin barrier in normal mice models. Materials and Methods The 0.5%, 1%, 2%, and 5% supramolecular SA hydrogel or hydrogel vehicle without SA was applied to mice's shaved dorsal skin once per day respectively. Tissue samples of the dorsal skin were harvested on day 14 and 28 of the serial application of SA for histopathological observation and transcriptomic analysis. Results Following topical supramolecular SA hydrogel therapy with various concentrations of SA (0.5%, 1%, 2%, and 5%) for 14 days and 28 days, there were no obvious macroscopic signs of impaired cutaneous health and no inflammatory or degenerative abnormalities were observed in histological results. Additionally, the transcriptomic analysis revealed that on day 14, SA dramatically altered the expression of genes related to the extracellular matrix structural constituent. And on day 28, SA regulated gene expression profiles of keratinization, cornified envelope, and lipid metabolism remarkably. Furthermore, the expression of skin barrier related genes was significantly elevated after the application of SA based on RNA-seq results, and this is likely to be associated with the PPAR signaling pathway according to the enrichment analysis. Conclusion Our findings demonstrated that the sustained topical administration of the 0.5-5% supramolecular SA hydrogel for up to 28 days did no harm to normal murine skin and upregulated the expression of genes related to the epidermal barrier.

The Role of Bioactive Compounds and other Metabolites from Mushrooms against Skin Disorders- A Systematic Review Assessing their Cosmeceutical and Nutricosmetic Outcomes. Curr Med Chem 2020; 27:6926-6965. [PMID: 32238131 DOI: 10.2174/0929867327666200402100157] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Revised: 11/19/2019] [Accepted: 12/15/2019] [Indexed: 01/03/2023]
Abstract
Bioactive compounds derived from mushrooms have been shown to present promising potential as cosmeceutical or nutricosmetic ingredients. Scientific data reviewed herein showed that extracts prepared from medicinal and edible mushrooms and their individual metabolites presented antiinflammatory, antioxidant, photoprotective, antimicrobial, anti-tyrosinase, anti-elastase, and anticollagenase activities. These metabolites can be utilised as ingredients to suppress the severity of Inflammatory Skin Diseases, offer photoprotection to the skin, and correct Hyperpigmentation. However, studies regarding the molecular mechanism behind the mentioned bioactivities are still lacking. Challenges associated with the use of mushroom extracts and their associated metabolites as cosmeceutical and nutricosmetic ingredients include several steps from the fruiting bodies to the final product: extraction optimization, estimation of the efficacy and safety claims, the use of micro and nanocarriers to allow for controlled release and the pros and cons associated with the use of extracts vs individual compounds. This systematic review highlights that mushrooms contain diverse biomolecules that can be sustainably used in the development of nutricosmetic and cosmeceutical formulations. Reports regarding stability, compatibility, and safety assessment, but also toxicological studies are still needed to be considered. Furthermore, some of the constraints and limitations hindering the development of this type of ingredients still require long-term studies to achieve major breakthroughs.

Abstract
Hydroxy acids (HAs) represent a class of compounds which have been widely used in a number of cosmetic and therapeutic formulations in order to achieve a variety of beneficial effects for the skin. We review and discuss the most frequently used classes of these compounds, such as α-hydroxy acids, β-hydroxy acids, polyhydroxy acids, and bionic acids, and describe their applications as cosmetic and therapeutic agents. Special emphasis is devoted to the safety evaluation of these formulations, in particular on the effects of their prolonged use on sun-exposed skin. Furthermore, we summarize the very limited number of studies dealing with the modifications evoked by topical application of products containing HAs on photocarcinogenesis. In spite of the large number of reports on the cosmetic and clinical effects of HAs, their biological mechanism(s) of action still require more clarification. Some of these mechanisms are discussed in this article along with important findings on the effect of HAs on melanogenesis and on tanning. We also emphasize the important contribution of cosmetic vehicles in these types of studies. Thus, HAs play an important role in cosmetic formulations, as well as in many dermatologic applications, such as in treating photoaging, acne, ichthyosis, rosacea, pigmentation disorders, and psoriasis.

Abstract
BACKGROUND A large number of commercial antiwrinkle and antiaging compounds are available to consumers for rejuvenation of facial skin ravaged by age or solar radiation. Experimental data on the histological effects of these commercial products in laboratory models are sparse. OBJECTIVES To compare the efficacy of topical application of five commercially available antiaging compounds (retinoic acid, glycolic acid, vitamin C, estrogen, and soy) on the dorsal skin. METHODS AND MATERIALS The effects were examined using light microscopic analysis of the epidermis in the normal nonirradiated hairless mouse. The agents were applied daily to dorsal tattooed areas for 2 weeks before histological assessment; neighboring untreated surface areas were used as control. Morphometric measurements of total epidermal width, nuclear volume of keratinocytes in three layers, and index of proliferating cell nuclear antigen according to immunohistochemistry were obtained and statistically analyzed. RESULTS Significant histomorphometric effects were noticed with all five agents, but more pronounced changes were obtained with glycolic acid, estrogen, and retinoic acid product. CONCLUSIONS These baseline data will be useful for future studies on the effect of ultraviolet radiation to cause photoaging and reparative effects of similar agents in this animal. The information contained in the report may provide guidelines to consumers and clinicians.

Abstract
Recreational and occupational exposure to seawater (SW), have increased but the effect of SW on skin has not been elucidated. The purpose of present study was to assess the effects of SW immersion on the dorsal skin in hairless mice. Adult hairless mice were individually immersed in SW for 3 h, 6 h and 12 h; then, full-thickness dorsal skin of 2 cm diameter was excised for pathological examination (light microscope), apoptosis detection (terminal deoxynucleotidyl transferase-mediated 2'-deoxyuridine 5'-triphosphate nick end labeling [TUNEL]) and proliferation index evaluation (immunohistochemistry). Normal and normal saline (NS)-immersed skin were used as controls. Histological examination revealed that there were randomly distributed cell deaths, presenting cell shrinkage, condensation of nuclear chromatin and eosinophilic cytoplasm in the epidermis, and neutrophil infiltration in the dermis, after SW immersion. Moreover, TUNEL showed low levels of apoptosis in normal (9.07 +/- 0.70%) and NS-immersed skin (9.99 +/- 1.22%). There was an apparent increase in the 6-h and 12-h SW immersed groups (29.90 +/- 6.85%, P < 0.01; 45.46 +/- 6.12%, P < 0.01, respectively). Ki-67 antigen was located in the basal layer of the epidermis and hair follicles, the rates of Ki-67-positive cells were 7.90 +/- 1.45% and 7.76 +/- 1.52% in normal and NS-immersed skin, respectively, and in the 12-h SW immersed group, the rate of Ki-67-positive cells reached 23.85 +/- 4.21% (threefold, P < 0.01). In each group, the rate of apoptosis was higher than that of proliferation. We conclude that SW immersion can cause time-dependent apoptosis and proliferation in the epidermis, and the overall effect of SW immersion is injury to the epidermis.

Abstract
The hydroxy acids are widely used in skin creams because of their exfoliating and rejuvenating effect on photoaged skin. As a member of this family, the salicylic acid derivative known in the literature as 2-hydroxy-5-octanoyl benzoic acid or beta-lipohydroxy acid has also been proposed as an exfoliant and as a treatment of photoaged skin and acne. This article reviews the effects of the hydroxy acids and compares them to those of the salicylic acid derivative. We propose the name C(8)-lipohydroxy acid (C8-LHA) for this derivative to differentiate it from other related compounds. The lipophilic nature of C8-LHA and its relatively slow penetration in the skin afford it an exfoliating effect that is efficient at low concentrations. It appears to have antimicrobial, anti-inflammatory, and anticomedogenic properties, which make it effective against acne. Its antifungal and exfoliating properties are also likely to prove useful in combating dandruff.

Abstract
Use of alpha hydroxy acids (AHA) to ameliorate specific dermatological problems with keratinization has become fairly widespread. The aim of this study was to evaluate the effects of the AHA derivative of glycolic acid, applied in different dosages, on rat skin using light and electron microscopy. Skin biopsies were taken from the dorsal side of rats (n=16) and at the end of each week after applying solutions containing AHA: week 1, 8% (n=5); week 2, 50% (n=5); week 3, 70% (n=6). The skin samples were fixed in 10% formalin for histology and 2.5% glutaraldehyde solution for electron microscopy and processed using routine protocols. Histological sections were stained with hematoxylin and eosin (H&E), Masson's trichrome and were also labelled for binding of a primary antibody against collagen I using the avidin-biotin-peroxidase method. The epidermal thicknesses were measured and the fibroblast count of the dermis was taken and the results compared using the statistical ANOVA test. Semi-thin sections were stained with toluidine blue-azure II solution and ultrathin sections were contrasted with uranyl acetate and lead citrate. Histochemical and immunohistochemical observations demonstrated that AHA treatment resulted in statistically significant increased thickness of the epidermis and an increase in numbers of active fibroblasts and in the amount of dense collagen, especially at higher dosages of AHA. Ultrastructural examination of rat skin from AHA-treated groups showed cytoplasmic vacuolization in epidermal keratinocytes, intercellular dysjunctions, and increased quantities of organized bundles of collagen fibers in the dermis. The use of AHA in appropriate dosages has been found to play an important role in the treatment of specific skin disorders, however, the harmful effects of use of AHAs at higher concentrations should not be ignored. We conclude that alpha hydroxyl acids have a wide spectrum of use in the field of dermatology but, due to side-effects, their use, dosage, and time frame should be restricted to the advice of dermatologists.

Abstract
Allele-specific competitive blocker PCR (ACB-PCR) amplification and quantification was developed for mouse p53 codon 270 CGT-->TGT base substitution and codon 244/245 AAC/CGC-->AAT/TGC tandem mutation. PCR products corresponding to p53 mutant and wild-type DNA sequences were generated. These DNAs were mixed in known proportions to construct samples with defined mutant fractions and the allele-specific detection of each mutation was systematically optimized. Each assay was used to analyze eight simulated solar light (SSL)-induced tumors. By analyzing mutant fraction (MF) standards in parallel with PCR products generated from tumor samples, p53 mutants could be quantified as subpopulations within the tumors. All eight tumors contained detectable levels of p53 codon 270 CGT-->TGT mutation. Three tumors had p53 MFs between 10(-4) and 10(-3). Five tumors had p53 MFs between 10(-3) and 10(-2). None of the eight mouse skin tumors had measurable levels of p53 codon 244/245 tandem mutation. Frequent detection of p53 codon 270 CGT-->TGT mutation provides additional evidence that a pyrimidine dinucleotide overlapping a methylated CpG site (Pyr(me)CG) is a susceptible target for SSL-induced mutagenesis. The absence of p53 codon 244/245 mutation in tumors may be explained by its mutant p53 phenotype and/or indicate that this site is not methylated. These initial results indicate that p53 codon 270 CGT-->TGT mutation may be a sensitive biomarker for SSL- or UV-induced mutagenesis. This mutational endpoint may be useful for evaluating the co-carcinogenicity of compounds administered in combination with UV or SSL.
