ABSTRACT

Background: The dermal extracellular matrix (ECM) is a dynamic scaffold composed mainly of proteins, with collagen as the key structural component providing resilience and support to the skin. Post-menopause, declining estrogen levels lead to a significant reduction in skin health, notably a 30% decrease in collagen types I and III within 5 years.

Aim: To discover natural extracts that stimulate collagen production.

Methods: We utilized PathwayStudio to analyze protein–protein interactions and identify regulators of essential collagen types. Our study assessed Glycyrrhiza uralensis extract's ability to boost collagen production and enhance dermal density both in vitro and in vivo.

Results: PathwayStudio analysis highlighted phytoestrogens including glycyrrhizin, isoliquiritigenin, liquiritigenin, liquiritin, and glabrol, as potential candidates. Liquorice rhizome (G. uralensis), used in traditional Chinese medicine, is rich in phytoestrogens like liquiritigenin. The G. uralensis extract increased collagen I and III gene expression and pro-collagen I protein levels in human dermal fibroblasts and inhibited UVB and pollution-induced matrix metalloproteinase-1 (MMP1) production. In an in vivo study, a topical formulation containing the extract significantly improved dermal density after 56days, measured by the DUB SkinScanner.

Conclusions: These findings suggest G. uralensis extract as a promising agent for enhancing collagen production and skin health, particularly in postmenopausal women. Further research is needed to explore its mechanisms and long-term effects.

Abstract: Cordyceps militaris is a medicinal mushroom widely utilized in traditional East Asian medicine, recognized for its diverse therapeutic properties. This review explores the potential of C. militaris-derived bioactive gels for applications in dermatology and skincare, with a particular focus on their therapeutic and anti-aging benefits. In response to the rising incidence of skin cancers and the growing demand for natural bioactive ingredients, C. militaris has emerged as a valuable source of functional compounds, including cordycepin, polysaccharides, and adenosine. These compounds exhibit multiple bioactivities, including apoptosis induction, cell cycle arrest, and anti-inflammatory effects, which have been shown to be particularly effective against melanoma and other skin cancers. Additionally, the antioxidant properties of C. militaris enhance skin resilience by scavenging reactive oxygen species, reducing oxidative stress, and promoting collagen synthesis, thereby addressing skin health and anti-aging requirements. The potential for incorporating C. militaris compounds into gel-based formulations for skincare is also ex amined, either as standalone bioactives or in combination with synergistic ingredients. Emphasis is placed on the necessity of clinical trials and standardization to establish the safety, efficacy, and reproducibility of such applications. By providing a safer alternative to synthetic agents, C. militaris-derived bioactive gels represent a promising advancement in dermatology and skincare.

Abstract

Background: Aging skin, exacerbated by external factors like UV radiation and pollutants, is a major cosmetic concern. Taurine, renowned for its antioxidant and anti-inflammatory properties, may combat skin aging. We performed mendelian randomization (MR) analysis to investigate the causal link between taurine and immune cells linked to skin aging.

Objectives: To investigate the association between taurine and immune cells using mendelian randomization, to thereby explore the mechanism through which taurine exerts anti-aging effects on the skin via immune modulation.

Methods: A MR approach was employed using taurine-level data from the Ieu Open GWAS Project and immunocyte traits from a large European cohort. MR-Egger regression, weighted median estimation, and inverse variance weighting all provided statistical insights into causality. Sensitivity analyses assessed the heterogeneity and pleiotropy among the genetic instruments used.

Results: MR analysis identified a causal relationship between taurine levels and 10 immunocyte phenotypes, with taurine found to be negatively and positively associated with three and seven phenotypes, respectively. Sensitivity analysis revealed no significant heterogeneity or pleiotropy, suggesting reliable MR findings.

Conclusion: This study provides insights into the immunological pathways by which taurine contributes to skin anti-aging effects, suggesting that increasing taurine levels could offer a novel strategy for anti-aging skincare.
