This study found that the 11R-No. 10 peptide, delivered transdermally, significantly inhibited melanogenesis and produced a whitening effect in a UV-induced sun-tanning guinea pig model without cytotoxicity.

This study found that overexpressing PKCδ in transgenic mice did not reduce squamous cell carcinoma development induced by UV radiation, despite its effectiveness against TPA-promoted cancer in these mice.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

Pollution exposure speeds up hair damage.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

New method measures minoxidil concentration faster, more accurately, and automatically.

In this study, male-pattern baldness was strongly associated with a higher risk of keratinocyte cancers, particularly squamous cell carcinoma and melanoma, likely due to increased sun exposure on the scalp rather than androgen levels.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study reports that a plant extract from Orobanche rapum can stimulate skin rejuvenation and protect cutaneous microbiota, potentially creating healthier skin.

This study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

This review discusses topical calcineurin inhibitors for cutaneous lupus erythematosus and reports no new clinical findings; the authors emphasize the need for more comparative studies with corticosteroids.

This study found that non-ionic silicone emulsion best protected hair color from UV-induced fading, outperforming honeysuckle extract and benzophenone-3, with significant effects in both dyed and virgin hair.

This study developed three spectrophotometric methods to effectively measure finasteride in bulk and tablet forms, providing accurate results that align closely with labeled claims.

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 observed that a five-week topical treatment with cold-pressed Rosa canina seed oil significantly reduced mean wrinkle scores and UV-induced spots in volunteers, suggesting potential anti-aging and photoprotective benefits attributed to its high carotenoid content.

This study found that nickel oxide nanoparticles synthesized using Alternanthera sessilis extract may have potential as antimicrobial, antifungal, and dye-removal agents.

This review discusses the antioxidant and photoprotective potential of Polypodium leucotomos for use as a natural sunscreen ingredient and reports no new experimental results; further studies are recommended to evaluate its effectiveness.

This study developed and validated a reliable RP-HPLC method for accurately quantifying dutasteride in pharmaceutical formulations and bulk pharmaceuticals using a Shiseido C18 analytical column, demonstrating precision, accuracy, and sensitivity across a concentration range of 10 to 22 ppm.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

In this study, a clear pattern of selective sweep was observed for the SLC24A5 gene, with high linkage disequilibrium and low haplotype diversity, but no clear correlation with UV radiation intensity was found.

This study developed chemical fingerprints to differentiate Eclipta prostrata and Wedelia calendulacea, two plants often confused and adulterated in the Indian herbal market, identifying distinct chemical profiles that can prevent such adulteration.

This study found that human skin melanocytes with low mutation burdens are smaller, less dendritic, and exhibit stem-like features, often residing in UV-protected hair follicles, suggesting their role in replenishing sun-damaged epidermis.

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 found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.

This conference proceeding abstract provides no new research results, focusing only on event details from the British Association of Dermatology's Forty-Sixth Annual Meeting held in Oxford in 1966.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

In this study, the researchers reported that their novel algorithm for hair restoration in dermoscopy images achieved high accuracy and texture preservation, outperforming other techniques in diagnostic accuracy and texture quality measures.

This review discusses the potential dermatological applications of Dendrobium officinale polysaccharides, noting their hair growth promoting, skin moisturizing, and antioxidant effects, but reports no new clinical results.

This review examines how male facial anatomy and behavior contribute to sexual dimorphism in facial aging, pointing to factors that accelerate aging in men but presents no new clinical results.
