This study found that redheaded individuals had higher levels of vitamin D precursor 25(OH)D3 compared to non-redheaded individuals, suggesting a physiological adaptation to low UVB radiation in Europe.

In this study, the anti-wrinkle effect of bone morphogenetic protein receptor 1a extracellular domain was significantly greater than that of retinoic acid in a mouse model, suggesting potential for BMP antagonists in skin or hair treatments.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This review discusses the role of zinc and its transporters in skin health and disorders, providing an overview without presenting new clinical results.

This study reviews current research to better understand how various environmental and lifestyle factors, collectively known as the exposome, impact hair health and aging, acknowledging that the detailed mechanisms remain partially understood.

This review reported that various nonsurgical treatments, like cryosurgery, photodynamic therapy, and topical medications, offer effective alternatives for basal cell carcinoma management, especially when surgery is unsuitable, and treatment decisions should consider tumor characteristics and patient preferences.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

This article reviews advancements in hair transplantation, highlighting robotic and follicular unit techniques, and discusses adjuvant modalities like platelet-rich plasma, lasers, and stem cells without reporting new clinical results.

This study synthesized a new organic sunscreen with broad photoprotective properties and demonstrated it to be non-toxic. The resultant cream, containing nanostructured lipid carriers, showed suitable application qualities and achieved a satisfactory SPF value of 16.

This review explores the clinical characteristics, risk factors, and treatment challenges of scalp basal cell carcinoma, noting its potential aggressiveness and difficulty in treatment, but reports no new clinical results.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This review discusses the safety of dermatological medications used during pregnancy, highlighting that retinoids have strong teratogenic risks and should be used with caution; it reports no new clinical results.

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.

In this study on a mouse model of vitiligo, NB-UVB/ADSC combination therapy improved oxidative stress and calcium homeostasis, but the protective effect was reversed by inhibiting Nr2 signaling.

This review discusses genetically-engineered mouse models for studying melanocytes and reports no new experimental findings; it emphasizes their potential to address unanswered questions in melanoma biology.

This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

This article does not contain an abstract and presents no new clinical findings, instead discussing prior cases and literature on infant alopecia universalis and the potential role of topical PUVA therapy.

In this study, researchers investigated EGCG's spectroscopic properties and its interaction with DPPG lipid, finding that both experimental and theoretical approaches agree on the electronic transitions and reveal an increased absorbance due to molecular interactions.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study investigated the effects of UV rays and particulate matter on hair porosity, finding that UV exposure increased porosity over time, and when combined with particulate matter, this effect was significantly enhanced in bleached hair.

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 paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study introduced and validated new spectrophotometric methods to simultaneously determine finasteride and tadalafil in Entadfi™ capsules with high sensitivity and without interference from excipients.

This systematic review found that photobiomodulation therapies using ultraviolet and infrared light effectively treated alopecia areata, while red and infrared light treatments were effective for androgenetic alopecia.

This study found that sunscreen and moisturizer use was associated with a higher likelihood of developing frontal fibrosing alopecia in the reviewed studies.

This review discusses the epidemiology, risk factors, clinical features, and management of scalp melanomas, highlighting their high mortality rates and specific challenges in diagnosis and treatment; it reports no new research findings.

This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

This article discusses the role and potential of plant stem cell extracts in cosmetics for their antioxidant and protective effects on skin cells, reporting no new clinical results; the authors highlight ecological and sustainable production methods.

Keratin film can effectively mimic human hair for testing hair damage.

This study reported that X-ray microscopy provides more intact images of hair's internal structure compared to transmission electron microscopy, particularly for observing fine details like cuticle coarsening and cortex cracks.
