This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.

This review examines the potential role of odorant receptors in human skin cells responding to flavor compounds and their implications for skin health and disease, without providing new clinical results.

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 article reviews various "white diseases" characterized by hypopigmentation or depigmentation and emphasizes the role of melanosomes in skin and eye color, but it does not present new clinical results.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

In this study, Asian breast cancer patients undergoing taxane-based chemotherapy in the adjuvant treatment group reported significantly increased hair loss, higher melanin index, and more wrinkles compared to other treatments, while most neoadjuvant group patients saw hair loss reversed six months post-surgery.

This study observed that exposure to heavy metal salts affected skin and hair morphology in mice, with lead acetate decreasing keratinocyte proliferation and zinc sulfate and sodium dichromate increasing it.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

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

This literature review on neurocosmetics found that both nature-derived peptides and synthetic molecules can improve skin concerns like aging and pigmentation, while also promoting emotional well-being; however, gaps in long-term efficacy and personalized approaches remain.

This study explored spontaneous repigmentation after phenol-croton oil peels in skin of color, finding that temporary hypopigmentation resolved by day 21 in both a black-skin domestic pig model and human clinical observations, highlighting potential for these procedures despite past concerns about pigmentation issues.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.

In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.

This review explores the extraction, characterization, and skin cosmetic effects of phenolic compounds and pigments from marine macroalgae, highlighting their documented benefits for skin health, such as whitening, moisturizing, photoprotection, and anti-aging effects, without adverse health impacts.

This study observed that the aqueous extract of roasted Alocasia macrorrhizos tubers led to hair follicle repigmentation and reduced epidermal thickness in a murine model of Vitiligo.

This study found that four sessions of Intense Pulsed Light treatment significantly improved signs of photodamaged skin in adult female patients, as demonstrated by patient satisfaction and 3D camera assessments.

This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

In this study of four Chinese goat breeds, black goats exhibited significantly higher melanin content, while Inner Mongolian cashmere goats had longer fiber lengths. These findings highlight genetic variations in coat color and fiber length, informing future breeding programs.

Light skin shows more inflammation from sun exposure than dark skin.

Vitamin D affects skin and hair by influencing cell behavior and melanin production.

This study found differences in melanin content and gene expression in skin under black and white hair of giant pandas, providing a basis for further research on hair color distribution and skin diseases.

This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

This study in a Lithuanian veterinary clinic observed diverse histomorphological skin changes in alopecic dogs caused by various rare diseases, including hyperkeratinization and pigmentation disorders.

This study found that hairless dog breeds have adapted to maintain normal body and core temperatures through structural changes like a thicker epidermis and the role of melanin in thermoregulation, with genetic mechanisms involving the FOXI3 gene governing hairlessness.

Different races and genders have unique skin and hair issues, requiring specialized care and more research for effective treatment.

This animal study observed that while topical MBEH and intraperitoneal phenol induced hair graying in eumelanic mice, they had little effect on pheomelanic mice, and amcinonide reduced certain epidermal melanocytes in both.

In this study, saponins from Korean red ginseng were found to protect against the harmful effects of airborne particulate matter on human skin cells by reducing oxidative stress, inflammation, leptin expression, and melanin production.

This study found that non-cutaneous melanocytes in mice are less sensitive to Kit signaling compared to cutaneous melanocytes, showing dependence on ET3 and HGF signaling.
