This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This study found that the immune-competent B6. Cg‐Tyr c−2J Hr hr /J congenic mouse line had a more pronounced delayed sunburn response and different proliferative skin reactions to UV exposure compared to SKH 1 mice.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

In this study, ultraviolet light did not significantly enhance or worsen hair growth induced by topical minoxidil in men with male pattern baldness.

More research is needed to understand hair aging and develop effective treatments.

This study confirmed the antioxidant role of rosemary, suggesting its potential use in treating inflammatory and infectious skin conditions, but emphasizes that more large-scale controlled trials are necessary to fully understand its clinical impact.

UV light might cause excessive hair growth by increasing PGE2 in the skin.

This study suggests that certain climate factors, particularly UV index and precipitation, may influence seasonal flare patterns in children with alopecia areata, especially those with atopic conditions.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

This review highlights the potential of valorizing citrus by-products, particularly hesperidin from orange peels, as sustainable ingredients in skincare for antiaging, pigmentation, wound healing, and UV damage protection, emphasizing hesperidin's role in a circular economy approach.

This article reviews historical uses of the term "lupus" for various skin disorders but provides no new clinical findings.

This study found that facial sun damage scores from UV photography correlate with skin cancer and melanoma risk factors, suggesting this technology may help identify individuals at higher risk.

This editorial synthesizes research on UV-induced skin damage, highlighting potential therapeutic strategies by mapping cellular changes, identifying molecular mechanisms, demonstrating melanocyte protection, and proving combination therapy effectiveness in conditions like vitiligo.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This study found that a hair-coating polyphenol complex significantly enhanced the mechanical strength, UV protection, and antistatic properties of damaged hair, suggesting potential benefits for hair treatment.

The book is a valuable guide for managing hair disorders, despite some missing details.

Skin aging reflects overall body aging and can indicate internal health conditions.

In this study, higher Fitzpatrick skin type, non-summer season, and non-White race were associated with vitamin D insufficiency in US children with alopecia areata.

This study found that ultraviolet A rays damage all hair types, with stronger adverse effects on colored and permanently waved hair, suggesting the use of sunblock products for hair protection.

This review discusses how menopause and hormone replacement therapy affect skin aging in women but reports no new clinical findings.

This study found that Eclipta alba (L.) Hassk herbal oil formulated with VCO demonstrated enhanced antioxidant, anti-inflammatory, and antibacterial activities, and provided UV protection, with EHO-18 identified as the best-performing version.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This study reviews melatonin's diverse roles in dermatology, highlighting its potential to protect skin from UV damage and oxidative stress, enhance DNA repair, and influence hair follicle cycling, suggesting therapeutic applications in skin care and hair renewal.

This review provides a comprehensive synthesis of skin aging research, highlighting the interplay of genetic and environmental factors, cellular mechanisms, and advances in diagnostic and therapeutic strategies, while also addressing current debates and future directions in the anti-aging field.

In this study, compliance with UV protection recommendations was highest among vitiligo patients compared to those with other cutaneous immune-mediated inflammatory dermatoses, indicating a need for tailored education to improve compliance across all groups.

This study observed that eco-friendly PALF forms a protective physical barrier on the skin, helping limit the impact of environmental pollutants and offering additional benefits for skin and hair in various cosmetic formulations.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.

This study reports that a novel UV-based crosslinking process for collagen sponges significantly decreases crosslinking time compared to traditional methods, and supports effective cell proliferation and wound regeneration in a mouse model, without causing abnormal angiogenic or immune responses.
