This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

This narrative review discusses lichen planus pigmentosus, including its variations, associated triggers, and management strategies, but reports no new clinical results.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

This study identified thyrotropin-releasing hormone (TRH) as a stimulant of wound healing in both frog and human skin models, suggesting it as a potential neuroendocrine wound repair promoter.

This article discusses techniques for creating natural-looking hairlines in hair restoration surgery and reports no new clinical results.

This article reviews the use of dermatoscopy and videodermatoscopy in therapeutic follow-up, noting that videodermatoscopy is a reliable tool despite potential cost issues with high magnifications.

This review discusses the challenges in diagnosing tinea capitis and highlights the need for laboratory confirmation and systemic treatment due to the limited effectiveness of topical antifungals; no new clinical results are presented.

This review highlights that in children, hair loss can be attributed to diverse conditions like alopecia areata and tinea capitis, and stresses the importance of a holistic approach to diagnosis and management, including psychosocial support due to limited effective treatments.

This article reviews recent trends and developments in dermoscopy, highlighting its expanding use beyond pigmented lesions, and reports no new clinical results.

This review discusses the challenges of using surrogate variables versus primary clinical end-points in PCOS trials and reports no new research results; the authors suggest focusing future studies on primary outcomes.

This review examines the increasing clinical applications of dermoscopy in diagnosing various skin conditions and highlights its potential to improve diagnostic accuracy and reduce unnecessary histologic confirmation.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

In this study, certain trichoscopic features were found to be sensitive and specific for diagnosing primary cicatricial alopecias and its subtypes using dermatoscopy.

This study identified distinct dermoscopic patterns associated with different types of scalp tumors, highlighting variability in lesions related to patient age, gender, and tumor thickness.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

This review explores the use of skin penetration enhancers like Transcutol® in various formulation systems, discussing their mechanisms and effectiveness in improving transdermal drug delivery without breaching the skin.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.
