This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This review explores the role of aging-related changes in skin, discussing how impaired skin barrier function may contribute to systemic inflammation, or "inflamm-aging," which in turn could impact the broader decline in organ and tissue function seen in aged individuals.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

This review highlights the potential of aromatic plants as natural antioxidants in cosmeceuticals, which may combat skin aging and promote rejuvenation by counteracting oxidative stress, offering a natural alternative to synthetic products with benefits like photoprotection and anti-wrinkle effects.

This study found that transgenic mice expressing a mutant CYLD protein lacking deubiquitinase function showed signs of premature aging and spontaneous tumor development, likely due to over-activation of specific molecular pathways and chronic inflammation.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

This review discusses the role of umbilical cord-derived mesenchymal stromal cells in skin rejuvenation and reports no new clinical results; it emphasizes their potential in delaying skin aging.

In this review, researchers explored how PGC-1α might improve aged skin barrier function by influencing mitochondrial function and reducing inflammation, factors that are linked to epidermal health during aging.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This review discusses the molecular mechanisms driving hair follicle degeneration in skin aging and emphasizes the role of the tissue microenvironment on stem cell function, but reports no new research findings.

This narrative review concluded that lifestyle factors such as nutrition, sleep, exercise, and social interactions play key roles in improving skin health and well-being with aging, and suggests social media campaigns could promote beneficial lifestyle changes in the future.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This study reports that aging in human skin involves early photo- and inflammation-related cellular changes, and suggests restoring KLF6 and HES1 expression might reverse some of these age-associated changes.

This study found that Polygoni Multiflori Radix (PMR) reduced collagenase and elastase activity after UVB damage in fibroblasts, suggesting potential anti-aging properties for cosmetic use.

This article reviews anti-aging strategies in dermatology, emphasizing the role of skin as a model for studying aging and promoting preventive and therapeutic interventions, but it does not present new findings.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

In this study, synthesized composite nanocarriers containing ribose and peptides demonstrated enhanced transdermal delivery, improved uptake by skin cells, promoted cell proliferation, enhanced antioxidant enzyme activities, and increased autophagy, suggesting a potential for more effective skin anti-aging treatments.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.
