This study found that human adipose-derived MSC exosomes (hADSC-Exos) may enhance dermal papillary cell proliferation and migration by activating the Wnt/β-catenin signaling pathway, potentially reversing the effects of dihydrotestosterone in androgenetic alopecia.

This study used single-cell RNA sequencing to characterize 19 distinct cell populations in sheep hair follicles, uncovering differentiation signatures and intercellular communication that may influence wool curvature and sheep breeding.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This review discusses the mechanisms and effects of dermabrasion for improving skin appearance and reports no new clinical results.

In this study, treatment with fractional CO2 laser combined with recombinant humanized type III collagen led to significantly better improvements in atrophic acne scars compared to laser treatment with saline, attributed to collagen upregulation and MAPK pathway activation in human dermal fibroblasts.

This review highlights the potential of plant-derived natural compounds as biocompatible and biodegradable materials in dermal and transdermal delivery systems, emphasizing their unexplored benefits and detailing recent advances in isolation techniques and drug delivery technologies.

In this study, using scRNA-seq, researchers detailed the gene expression and cell differentiation processes in goat fetal horn buds, identifying crucial roles for dermal and epithelial cells in horn initiation and highlighting potential genetic factors involved in horn morphogenesis.

This review discusses the cosmetic applications and healing phases of microneedling and reports no new clinical findings; the authors highlight its use for skin and hair treatments without epidermal damage.

This review examines the use of microneedles for treating alopecia areata, highlighting their ability to enhance drug delivery through the skin by bypassing the outer barrier and promoting hair growth with minimal invasiveness.

This study found that hypoxic preconditioning of nanofat from donor mice reduced its vascularization capacity in vivo, suggesting that this approach cannot currently enhance nanofat's regenerative potential.

A man had a non-cancerous, fast-growing skin lump on his arm that was removed with surgery.

This review discusses microneedling radiofrequency in cosmetic dermatology, particularly for skin texture improvement and various conditions, and reports no new clinical results.

This review examines the use of commonly used dermatological drugs like chloroquine, hydroxychloroquine, ivermectin, antiandrogens, and melatonin in COVID-19 treatment, but reports no new clinical findings.

This study compared fluid PRF and PRP for treating atrophic acne scars and found PRF to be more effective, particularly when combined with needling. Both treatments improved scars, but PRF showed higher therapeutic response, suggesting it as a superior alternative for acne scar treatment.

This abstract is a poetic narrative that recounts a personal experience involving hair loss, medical examinations, and reflections on life, but it reports no scientific findings or new clinical results.

This abstract does not provide research results or a summary of findings, but only lists author affiliations and contact information.

This literature review conducted a comprehensive analysis of existing studies on micro-needling mesotherapy in dermatology and aims to offer a practical guide for its clinical application, though it provides no new experimental findings.

This study found that repeated microneedle stimulation in mice promoted hair growth and increased the expression of hair-growth-related genes, suggesting potential therapeutic uses for alopecia.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

This systematic review explored the feasibility of adding skin needling to an aesthetic clinic's offerings, examining financial implications, time investment, and its integration with existing treatments. Various challenges and learning opportunities were noted, underscoring the complexity of introducing a new service.

This article examines anticytokine therapies for autoimmune diseases, highlighting the potential of anti-interferon-γ as a universal treatment for certain conditions and noting varying effectiveness of tumor necrosis factor-α inhibitors.

This review examined three studies on dermaroller monotherapy for hair loss, finding inconsistent efficacy and diverse methods, with risks of follicular damage and infection noted; standardized protocols are urgently needed for safe practice.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

This review explores the development and cosmeceutical applications of microneedles for skin treatment, without reporting new clinical results, emphasizing safety and public perception as key factors for commercialization.

This study found that adding platelet-rich plasma to microneedling improved outcomes for atrophic acne scars more than microneedling alone, according to both quantitative and qualitative assessments.

This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.

This review discusses the application of active transdermal technologies in cosmetic devices for skin restoration and enhancement, reporting no new clinical results.

This review summarizes the positive clinical response of using platelet-rich plasma as an adjuvant in skin rejuvenation treatments, with no identifiable complications, suggesting a promising outlook for its future use.

This review discusses the potential risks and effects of chemical relaxers on hair and scalp health, reporting no new clinical results; the authors emphasize dermatologist guidance to mitigate these issues.
