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.

HA-iMSC-EVs can improve skin aging by boosting cell growth and restoring collagen and elastin.

In this study, aged mice showed better regenerative skin outcomes than young mice, linked to a specific fibroblast subpopulation and enhanced signaling interactions that promote regeneration. EREG treatment improved young mice's skin regeneration, suggesting potential for scarless therapies.

This study found that different stressors causing premature senescence in fibroblasts resulted in distinct changes in lipid profiles, particularly sphingolipids, which may affect the behavior of senescent skin cells.

Senescent fibroblasts can help start tumors in normal skin cells.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

In this study, araliadiol, a plant-derived compound, exhibited senomorphic effects in three dermal fibroblast senescence models, suggesting its potential as a topical treatment to mitigate skin aging by reducing certain senescence-related markers and increasing procollagen type I content.

This study suggests that subtle modifications in ribosomal RNA methylation may influence cellular physiology and contribute to ribosome specialization in senescent human dermal fibroblasts.

This study identified Azithromycin and Roxithromycin as novel senolytic antibiotics that effectively target and reduce senescent human fibroblast cells.

Reactive lipids from aging cells change the extracellular matrix, affecting cell function and inflammation.

Mechanical stretching can improve or hinder skin regeneration depending on duration.

In this study, researchers found that the compound BMS-470539 induced a senescence-like state in fibroblasts from systemic sclerosis patients, reducing fibrosis-associated markers in vitro and decreasing skin thickness in a mouse model of skin fibrosis, suggesting a novel therapeutic strategy for managing fibroblast-driven diseases.

UVA exposure slows skin wound healing, but α-klotho can reverse this effect.

In this study, researchers investigated changes in ribosomal RNA modifications associated with stress-induced cellular senescence in human skin cells, identifying potential biomarkers and targets for interventions to mitigate skin aging.

This study suggests that stress-induced premature senescence of dermal papilla cells may contribute to hair follicle aging by impairing critical epithelial-mesenchymal interactions and promoting inflammatory cytokine production.

This study identified distinct and diverse fibroblast populations in female scalp cells that lose their signature and identity with age, highlighting significant age-related changes, such as increased fibrosis, DNA damage, and senescence, which may affect scalp dermal support for healthy hair follicles.

This study investigated age-related changes in female scalp dermal fibroblasts, finding alterations in gene and protein expressions associated with fibrosis and senescence, which could potentially affect hair follicle health and contribute to aging-related hair changes.

This study found that inhibiting NF-κB Essential Modulator (NEMO) in senescent murine dermal fibroblasts successfully reduced key factors associated with the senescence associated secretory phenotype (SASP), highlighting its potential as a therapeutic target for aging-related diseases.

This study found that the small molecule honokiol may protect against inflammation, collagen breakdown, and cell damage caused by cigarette smoke in skin cells cultured in vitro.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

In this study, DMC selectively eliminated senescent cells in old mice, prevented hair loss, improved motor coordination, and reduced senescence-associated secretory factors, suggesting its potential as a senolytic treatment.

This study explored the molecular factors behind delayed wound healing in obesity, highlighting that systemic changes like inflammation and collagen deposition alterations contribute to sustained skin inflammation and reduced mechanical resistance.

This review reports that exosomes show potential in regenerative and cosmetic dermatology for applications like wound healing and hair loss mitigation, but their clinical use is currently limited by high costs, complex processing, and sparse clinical evidence.

The study identified increased IL-24 expression in keratinocytes and fibroblasts exposed to particulate matter, contributing to skin aging by promoting conditions similar to age-related changes such as increased MMP1 expression and decreased type I collagen production.

This study suggests that the phenotype of melasma in women is influenced by structural and cellular changes across the epidermal-melanin unit, not just melanocyte hypertrophy, highlighting potential roles for dermal damage repair and fibroblast senescence.

This review examines the complexities of age-related skin healing and discusses how translating findings from model organisms to humans could enhance understanding and treatment of impaired regeneration in aging populations, but it reports no new clinical results.

This review discusses the pathogenesis of melasma, including genetic, environmental, and hormonal factors, and highlights potential avenues for new treatments and preventive strategies, but reports no new experimental findings.
