This article discusses potential roles for retinoids in hair regrowth and proposes future studies, reporting no new experimental results.

This study found that treating the skin of Mexican hairless dogs with different tretinoin formulations reduced comedones and lightened skin color, suggesting its potential as a model for evaluating retinoid activity.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

This review discusses various treatments for hair loss, such as topical agents, oral minoxidil, and laser therapies, but reports no new clinical results; debates on issues like post-finasteride syndrome are also covered.

This study found that compounded topical minoxidil was associated with higher adherence, fewer side effects, and more clinical improvement in Black women compared to over-the-counter minoxidil.

This study found that Compound Diandao Pulvis Drug Facial Mask improved some signs of acne in a rabbit ear model, but its effects were not significantly different from tretinoin cream.

In this review, the authors emphasize the importance of understanding drug chemical structures to help general physicians better manage and treat acne, although no specific results are reported.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

This study developed a stable cell line model to evaluate hair differentiation activity, offering a new tool for screening drugs that promote hair growth using mouse iPS cell-derived systems.

This article discusses variations in retinoid pharmacokinetics affecting their toxicity and clinical efficacy, but reports no new results; the authors emphasize considering toxicity in selecting suitable compounds.

This study found that 2MbisP increases epidermal thickening more rapidly than atRA in rhino mice, while both compounds similarly reduce utricle size.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

This study suggests that dietary vitamin A may influence alopecia development and progression, but the mechanisms remain unclear, highlighting the interplay between genetics and nutrition in these hair loss conditions.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

In this laboratory study, α-mangostin was found to significantly reduce melanin content and downregulate pigmentation-related genes in cultured skin and B16F10 cells, suggesting potential application as a natural whitening agent in sunscreen development.

In this study, SMR-2 and SMR-6, retinoid analogs, were found to be approximately 100 times more toxic than retinoic acid in male mice, primarily affecting skin, immune, and reproductive systems.

This study suggests that short-term treatments with specific small molecules may enhance the differentiation potential and stem cell properties of human amniotic fluid stem cells.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

This review of acne management strategies highlights current treatments, such as topical and systemic therapies, procedural methods, and dietary changes, while also discussing emerging options like biologics and probiotics as potential future treatments, emphasizing personalized care due to acne's complex nature.

This study found that SMR-2 and SMR-6, analogs of retinoic acid and retinol, were approximately 100 times more toxic than retinoic acid in mice, inducing hypervitaminosis A and affecting various organs and tissues.

This review discusses plant-based alternatives to retinoids for dermal antiaging and hair health, highlighting roles for cytokinins and phytoestrogens and reports no new results.

In this study, a case of lichen amyloidosis on the scalp significantly improved with a 2-month topical treatment using clobetasol propionate/all-trans retinoic acid ointment.

This review discusses various treatment options for adult female acne, highlighting the need for tailored approaches due to individual patient needs and reports no clinical outcomes.

This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

This book reviews the various types of acne and acneiform conditions, as well as their treatment options, with expert insights from multiple fields.

This study found that minoxidil combined with all-trans retinoic acid additively promoted hair growth in vitro by enhancing cell survival and reducing apoptosis compared to minoxidil alone.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

This study identified a novel mechanism by which dsRNA-induced TLR3 activation and retinoic acid pathways contribute to new hair follicle formation after deep wounds in mice and suggested a similar potential in humans.

Retinoids are effective for acne but can cause serious side effects.

This article reviews the current status of oral retinoids in dermatology and reports no new clinical findings.
