This study analyzed gray hair, revealing that it differs from pigmented hair in follicular activity, oxidative balance, and structure, impacting coloring processes and necessitating adapted techniques to maintain hair quality.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

This study found that adolescent men in Ireland are more likely to prefer keeping a baby over abortion in a hypothetical unplanned pregnancy, influenced by their anticipated regret and perceived familial attitudes.

This study discusses how dermatological issues in athletes can arise from or be exacerbated by mechanical trauma, infections, and environmental factors, highlighting the importance of thorough history and examination to differentiate these from other skin conditions.

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 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.

The researchers emphasize the limited scope of existing studies on lip aging, highlighting issues that include collagen loss and the deepening of lip lines with age, and suggesting a need for further research to guide cosmetic and clinical interventions.

This review discusses the application of mesenchymal stem cells and their secretory factors for skin and hair regeneration and reports no clinical results; the authors highlight the progress and call for practical applications.

This chapter reviews the potential of adipose-derived stem cells for skin aging and hair loss treatments but reports no new experimental results; the authors highlight these stem cells as a promising regenerative resource.

This study found that sex hormone-binding globulin promotes facial aging, while sex steroid hormones such as testosterone and estradiol inhibit it, with growth hormone levels showing no significant effect.

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

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 paper reviews the role of the telomere-telomerase system in cellular ageing and cancer, discussing potential therapies but reporting no new experimental results.

This review summarizes key characteristics of men's health issues such as erectile dysfunction and prostate cancer, along with specific nursing considerations, and reports no new research results.

This review concluded that near-infrared and red light photobiomodulation shows potential for certain ocular conditions like age-related macular degeneration and dry eye disease, but clinical evidence is still mixed and insufficient to establish it as a standard therapy.

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 theoretical review analyzes how stress affects hair loss through hormonal and neural pathways, indicating that knowledgeable hairdressers could help in early detection and guide clients toward medical interventions, highlighting a potential collaboration between aesthetic care and medical treatment for stress-induced alopecia.

This presentation explores burnout and compassion fatigue among healthcare professionals, detailing their causes, symptoms, and consequences, and emphasizes strategies for prevention and management, such as mindfulness and organizational support, to improve both provider and patient outcomes.

This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.

This study observed that different types of hairline recession increased the perceived facial age of East Asian males, with hair loss type C2 or U2 making those in their 30s appear significantly older.

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

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study reports that a newly developed polyherbal phospholipid complex cream containing Citrus auranticum and Glycyrrhiza glabra extracts improved polyphenol retention in the skin, suggesting potential as an anti-aging cosmeceutical.

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 study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This narrative review highlights the critical role of intracrine hormone production in peripheral tissues, suggesting that continuous-release subcutaneous testosterone pellet therapy may offer a more effective symptom-driven approach for aging populations, though large-scale randomized controlled trials are needed for confirmation.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

This study in diabetic db/db mice found that treatment with the antihypertensive agents minoxidil or nebivolol stimulated elastogenesis and inhibited elastolysis, leading to restored elastic fibers, reduced aortic stiffening, and normalized blood pressure.
