This article discusses mouse genetic studies to explore factors influencing melanogenesis, highlighting pH and cysteine's roles, and proposes a hypothesis for human hair color diversity; it reports no new results.

This article reviews the use of light-based technologies for hair removal, detailing different laser systems and treatment protocols, but reports no new clinical results.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

This report describes two cases of VKH disease and SO where severe alopecia, likely due to incomplete treatment, improved following systemic steroid therapy.

This article reviews practical approaches for managing dermatologic conditions in patients with skin of color and reports no new clinical findings.

This article discusses the roles of different proteins in melanogenesis and proposes a hypothesis to explain the diversity of human hair pigmentation, but it reports no new experimental results.

This study proposed a model that accurately predicts skin condition using genotype information and machine learning, suggesting potential for creating customized cosmetics.

This review examines the genetic factors influencing coat color in horses and donkeys, highlighting key genes like MC1R, TYR, MITF, ASIP, and KIT, and discusses implications for selective breeding and the relationship between coat color and specific equine diseases.

This case report details a rare instance of a giant cellular blue nevus on the scalp, highlighting its potential to damage underlying bone and hair follicles, alongside a separate alopecia areata lesion successfully treated with topical corticosteroid.

This study found that facial threading decreased skin roughness and improved subjective assessments of skin smoothness and color after three sessions.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This study examined how varying concentrations of kaolin base in mud masks with red pomegranate peel extract influenced properties like viscosity, pH, and drying time, finding that a formulation with 22.5% kaolin performed best in terms of physical characteristics and enzyme inhibition.

This review discusses the effects of hormonal changes on hair follicles, concluding that hormones like androgens and estradiol significantly influence hair growth and cycle, while the roles of other hormones are still being researched.

This review discusses the evidence for using oral medications to treat central serous chorioretinopathy, highlighting eplerenone as having the most support despite a lack of robust efficacy across studies.

This source provides no abstract, offering no results or conclusions on a case involving a 14-year-old boy with abrupt-onset hair changes presented in a photo quiz format in Pediatric Dermatology.

This study calculated the molecular properties of finasteride using PM3 methods, providing insights into its characteristics despite the lack of published data on these properties.

This letter discusses preliminary findings suggesting wrist actigraphy may be useful for monitoring sleep in cirrhotic patients, but emphasizes the need for further validation before replacing sleep diaries.

Radiofrequency devices effectively tighten skin without surgery.

In this study using human cell cultures, type 1 5α-reductase was found to vary in both protein heterogeneity and expression levels across different types of skin cells.

This study found that incorporating adipose-derived stem cell conditioned medium into a polysaccharide hydrogel effectively reduced scar hyperplasia, with the combination offering better outcomes in preventing hypertrophic scarring compared to the medium alone in a rabbit ear model.

This study revealed that differential gene and protein expression in the "Yufen I" H line chicken breed is crucial for Columbian plumage coloration, particularly in the melanogenesis pathway.

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.

In this study, Polygonum multiflorum Radix promoted hair growth in mice, with oral administration being more effective, likely through FGF-7, while topical application favored SHH-related mechanisms.

In this study, the researchers found that the picosecond pulsed alexandrite laser (PSAL) may be as effective and safe as the Q-switched alexandrite laser (QSAL) for treating freckles in Chinese patients.

This review discusses recent in vitro and in vivo research suggesting that components of ginseng, such as ginsenosides and gintonin, may have potential skincare benefits, including anti-aging effects and treatment of skin conditions like atopic dermatitis and hypertrophic scars.

This article discusses the effectiveness of fat transfer for facial rejuvenation across all ethnicities, emphasizing its potential as both a primary method and a complement to traditional techniques, but reports no new clinical findings.

This study found that puerarin, derived from Pueraria thunbergiana, may stimulate melanogenesis and prevent follicular depigmentation in a hair graying mouse model.

This review examines clinical trials on polyphenol-based therapies for dermatological conditions, suggesting potential benefits for anogenital warts, alopecia, and acne, but calls for more rigorous trials.
