This study found that splenic melanosis in C57BL/6 mice is associated with synchronized skin melanization during hair cycles, but decreases with age.

In this case report, a 22-year-old female was diagnosed with follicular Dowling-Degos disease based on clinical and histological findings, with symptoms including skin lesions confined to hair follicles. The report emphasizes the importance of differentiating this rare variant from similar conditions for proper management.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This study found that Philippines stingless bee propolis extract promotes hair growth in mice by activating the Wnt/β-catenin signaling pathway and stimulating hair follicle development.

This study provides evidence that Fernblock® upregulates antioxidant pathways in cultured keratinocytes, potentially protecting against damage from fine pollutant particles.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This review discusses the physiological skin changes during pregnancy and reports no new clinical results, emphasizing the importance of distinguishing these changes from pathological conditions.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This essay reviews the role of human scalp hair follicles in the "brain-skin connection," highlighting their dual function as targets and sources of neurohormones, without reporting new experimental results.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This article reviews advancements in understanding skin regeneration and suggests that bioengineering skin surrogates may soon enhance treatments for skin trauma, but it presents no new clinical findings.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

This review discusses skin diseases related to contraceptive use, reporting potential issues with oral contraceptives and infrequent reactions to mechanical or barrier methods without new clinical findings.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This review discusses the long-term cutaneous and ocular complications from sulfur mustard exposure in the Iranian population, identifying pruritus and malignant changes as significant issues and highlighting eye surface damage leading to visual decline.

This review discusses the synthesis and biological activities of jasmonates, highlighting their potential as drugs and prodrugs, but reports no new clinical results; further research and trials are anticipated.

This review discusses the identification and classification of different wrinkle types based on histological features and microanatomy, emphasizing their varying responses to treatments, and reports no new clinical results.

This article examines differences in aging among ethnic populations and highlights cosmetic procedures specific to skin of color, but reports no new research findings.

This study observed that follicular dysplasia in Weimar Pointers produces histopathological features and hair abnormalities similar to color dilution alopecia, though less severe.

This study found that Blumea eriantha silver nanoparticles promoted hair growth in treated animals, with activity comparable to minoxidil in terms of anagen follicle transition.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This review explores the potential benefits of natural plant-based products for skin anti-aging, assessing effects on wrinkles, oxidative stress, pigmentation, and hydration, while also underscoring the importance of lifestyle factors such as diet, exercise, and sleep in skin health maintenance.

Malassezia species may contribute to hair loss in AGA patients.
