This study explores the role of cell competition in maintaining genomic quality in epidermal stem cells and proposes that this process might influence cancer development in skin tissues.

This source describes Kudo Anti-Aging Gummies, which are promoted as a natural supplement designed to reduce wrinkles, enhance hair and nail health, and improve skin appearance by restoring collagen, with results purportedly visible within 1-2 months.

This supplement reviews advancements in the science of aging, including facial age simulation and stem cell applications for hair restoration, and reports no new clinical results.

This supplement chronicles the 2020 Science of Aging Symposium, highlighting emerging discoveries in aging research, such as gene therapies and using AI for visualizing skin, without reporting new clinical results.

This review covers recent findings on skin aging, emphasizing how cellular senescence and changes in the microenvironment impair stem cell functions, affecting skin regeneration.

This thesis analyzed four skin aging features and their relationships with lifestyle, physiological factors, and genetics.

This review discusses the aging-related changes in hair properties, their impact on styling, and potential interventions, without providing new clinical results.

This research observed that chronological age, rather than hearing loss, primarily affects the auditory cortex in aging, and found that brain aging in PolG mice mirrored that of wild-type counterparts, suggesting differential tissue sensitivity to mitochondrial dysfunction.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

This chapter reviews Hutchinson–Gilford progeria syndrome as a model for studying aging but presents no new findings, covering its genetic basis, clinical features, and existing treatments.

This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.

This study found that gypenosides from Gynostemma pentaphyllum increased procollagen synthesis in vitro and reduced periorbital wrinkles by about 14% in a clinical trial with 24 women.

This research found that Foxc1 promotes quiescence in hair follicle stem cells and identified COL17A1 depletion, due to DNA damage, as a cause of hair thinning and loss during aging.

The book provides practical guidance on cosmetic facial surgery for clinicians.

This study found that topical niacinamide significantly improved the appearance of wrinkles, skin yellowing, and elasticity in aging facial skin over 12 weeks.

Dihydrotestosterone gel improved well-being and sexual function in older men without negatively affecting prostate health.

This review discusses the commonly observed pathological findings in progeroid mouse models and highlights the importance of understanding mouse strain backgrounds and progeria-related phenotypes for accurate pathology data interpretation.

This article discusses the impact of estrogens on skin aging, highlighting the potential benefits and unresolved effectiveness of alternatives like phytoestrogens and selective estrogen receptor modulators; it reports no new clinical results.

This study found that a topical gel formulation containing rice water demonstrated in vitro antioxidant activity and elastase inhibition, suggesting its potential as an anti-aging skincare ingredient.

This review discusses the long-term effects of gender affirming hormone therapy and reports no new clinical findings, recommending a shared decision-making approach to balance benefits and risks for transgender individuals.

This review discusses the mechanisms of skin aging, highlighting the roles of stem/progenitor cells, genetic and environmental factors, and suggests potential for cell-based therapies, but reports no new experimental findings.

This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

This article discusses the effectiveness of fat transfer for facial rejuvenation across all ethnicities, emphasizing its potential as both a primary method and a complement to traditional techniques, but reports no new clinical findings.

This study concluded that hormonal replacement therapy can improve skin ageing symptoms by increasing skin thickness and alleviating dryness and hyposeborrhoea in postmenopausal women.

In this study, researchers found that an ethyl acetate extract of the green microalga Scenedesmus deserticola significantly increased the viability of human dermal fibroblasts by over 20% compared to a control and identified a potent anti-UV compound, loliolide, through further fractionation.

This study found that encapsulating coffee berry extract in nanoliposomes improved its stability, reduced toxicity, and enhanced its anti-aging effects on skin elasticity and lightening more than free extract.

This study observed that amniotic allografts provided similar aesthetic improvements with less downtime and quicker results compared to PRP treatment for midface volume enhancement.

This article highlights the need for dermatologists to understand male-specific anatomical and physiological differences to optimize aesthetic treatment outcomes for men, but it reports no new clinical results.
