This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

This study concluded that a liquid serum formulation delivered two fluorescent dyes to deeper follicular regions more effectively than nanoparticle systems.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This article describes a method using the CUBIC protocol to clarify and visualize molecular and cellular interactions in mouse skin biopsies at single cell resolution, but does not provide new biological findings.

This study found that a CLSM-based approach could semi-quantitatively assess the transdermal penetration behavior of fluorescent dyes with different lipophilicities, offering a tool for early-stage screening of compound penetration.

This study developed a biodegradable nonwoven textile using a starch-based biopolymer and fruit extracts, resulting in materials that are stronger, more hydrophilic, and capable of releasing beneficial compounds over 72 hours, positioning them for potential use in medical, healthcare, and cosmetic applications.

Understanding how our bodies interact with mosquito-borne viruses is crucial because there are few treatments and vaccines.

This review discusses melanocyte biology and its genetic and molecular basis, highlighting its relevance in understanding diseases like vitiligo and albinism, and reports no new findings.

This study found that adiponectin significantly enhanced lipid production in human sebaceous glands and may be a potential target for treating conditions with reduced sebum production.

This study found that a topical transethosomal system may enhance the skin penetration and deposition of naftifine compared to a marketed cream, potentially overcoming the stratum corneum barrier.

In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

In this ex vivo and mouse model study, Tofacitinib-loaded nanoparticles demonstrated enhanced delivery of the drug into hair follicles and reduced inflammatory effects compared to conventional forms, indicating potential for safer, topical use in treating alopecia areata.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study reports that Wise is expressed in specific patterns during the morphogenesis of chick embryos, particularly in regions associated with known signaling molecules like Wnt, Bmp, and Shh.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study on diabetic rats reported that Ziziphus spina-christi ethanol leaf extract significantly reduced blood glucose levels and improved liver and kidney function, suggesting possible benefits in managing diabetes symptoms in this animal model.

This review discusses the potential of Ziziphus species and its extracted oil as new therapeutic agents in drug development and highlights the need for further studies to fully exploit this species for human health benefits.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

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.

In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.
