This study's literature synthesis suggests that silymarin, derived from milk thistle, may offer protective benefits for the skin, including defense against UV damage and support for wound healing, though further clinical studies are needed.

This study found that a hair-coating polyphenol complex significantly enhanced the mechanical strength, UV protection, and antistatic properties of damaged hair, suggesting potential benefits for hair treatment.

In this systematic review and meta-analysis, researchers found that exosome therapies significantly improved facial wrinkles by 20.2% and enhanced hair density and thickness by 23.6% and 18%, respectively, despite challenges in generalizability due to study heterogeneity and nonstandardized protocols.

This study found that supplementing with 1.5% α-ketoglutaric acid significantly improved the performance, hair follicle density, and antioxidant capacity in Rex rabbits, potentially by enhancing the Wnt signaling pathway and reducing amino acid catabolism.

In this clinical study, a vegan collagen builder (VEGCOL™️) was shown to safely and effectively improve hair growth, skin smoothness, wrinkle reduction, and joint pain relief in adults, with enhancements varying by dose over a 60-day period.

This article explores the potential applications of polyglutamic acid in cosmetics, discussing its benefits for skincare and haircare, but reports no new experimental results.

This study found that boosting the synthesis of neural-derived 17β-estradiol effectively counteracted the impairment of hippocampal long-term potentiation caused by amyloid beta 1-42 in rat hippocampal slices, with the effect seemingly linked to glutamate NMDAR signaling.

This review discusses the use of spinal fMRI to investigate the brainstem and spinal cord and highlights its potential for understanding functional integration, but it reports no new experimental results.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This study explores the complex mechanisms of skin aging, including cellular senescence and disrupted communication, and highlights rejuvenation strategies like gene expression rewiring and microbiome modulation, offering potential frameworks for regenerative therapies and precise interventions in skin and systemic aging.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This study found that multiparametric ultrasound effectively detects real-time scalp changes caused by vasoconstrictive cosmetic agents, demonstrating its potential as a non-invasive tool for evaluating trichological treatments.

This article reviews technical aspects of using autologous fat transfer for facial rejuvenation and examines existing evidence for stem cell and platelet-rich plasma therapies in aesthetic practice, reporting no new results.

This review highlights the potential role of mathematical and computational approaches in enhancing and accelerating the clinical translation of regenerative medicine products but reports no new clinical findings.
