This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

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.

In this study, researchers characterized the normal scalp hair properties in South Koreans, observing that hair density declined with age and varied across scalp sites, while hair thickness patterns remained relatively stable until later in life.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

In this study, overexpression of miR-29 in mice led to aging-related phenotypes and early lethality, demonstrating its significant role in driving aging processes.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.

This review highlights research reporting that oral collagen peptide supplements are effective in enhancing skin elasticity, hydration, and reducing wrinkles, although results vary across studies. Oral supplementation was generally well-tolerated, and further investigation is needed to optimize formulations and explore topical application challenges.

This review discusses how sex hormone levels and local steroid synthesis influence gender differences in aging skin, reporting no new clinical results.

This study observed that women with cicatricial hair loss had an increased risk of hypertension, which may share overlapping biological origins.

This study suggests that the activation of box A in mesenchymal cell models may enhance stem cell properties, increasing the expression of stemness markers like OCT4, NANOG, and SOX2.

This article discusses the structure and function of the skin's epidermis, detailing its role as a protective barrier and nutrient exchange system, without presenting new research findings.

This study found that a topical cream containing CBD and EPA reduced signs of extrinsic skin aging, including wrinkle volume and skin elasticity, in clinical and laboratory settings.

Skin problems in the elderly are unique and may indicate other diseases, involving changes in skin, hair, nails, and increased cancer risk.

This review suggests that a dual treatment approach using Nourella® cream with nano-encapsulated Retilex-A® and per-oral Vercilex® tablets may effectively improve skin thickness, elasticity, and overall rejuvenation in aging skin, as shown in interventional studies.

Menopause affects skin and hair, and more research is needed for effective treatments.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

This narrative review highlights the need for diabetes-informed approaches to aesthetic dermatology as accelerated skin aging in diabetic patients complicates the safety and effectiveness of cosmetic procedures.

This study explores the potential roles of exosomes in anti-aging applications, highlighting their ability to modulate inflammation, promote tissue regeneration, and transfer bioactive molecules to rejuvenate aging tissues and reverse cellular dysfunction.

BrdU speeds up hair follicle aging and reduces hair quality.

This study highlights the critical role of mitochondria in skin aging and wound repair, suggesting that targeted interventions such as antioxidants, NAD⁺ boosters, and NRF2-based therapies may enhance mitochondrial function and improve cutaneous health.

This review reports that natural compounds show promise in slowing skin photoaging by targeting cellular pathways in keratinocytes and fibroblasts. However, comprehensive clinical studies are needed to verify their efficacy and safety.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This study reviewed the prospects and challenges of using stem cells from adipose tissue in regenerative medicine for facial rejuvenation, emphasizing the need for further research to ensure patient safety before these methods can become routine in cosmetic and reconstructive surgery.

This study found that a combination of photoprotector and nighttime formulations with essential oils improved skin barrier function and structural characteristics in young men's oily, acne-prone, and photoaged skin.

This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

This review discusses the role of antioxidants in managing oxidative skin damage and reports no new results, emphasizing the need for understanding their mechanisms, limitations, and risks for safe use.
