This comprehensive review examines the current applications and future directions of exosomes in dermatological practice. The analysis of available literature reveals a growing market of exosome-based products internationally and within the United States, with diverse formulations primarily derived from human stem cells. Clinical studies of exosomes have demonstrated clinical efficacy in addressing skin aging, scarring, hair restoration, and melasma. Additionally, exosomes show potential as therapeutic agents for inflammatory skin conditions like atopic dermatitis and as prognostic and diagnostic biomarkers for various dermatological disorders including psoriasis, vitiligo, and melanoma. Despite promising results, challenges remain in the standardization of isolation protocols, optimization of delivery systems, and establishment of regulatory frameworks. Proper characterization of exosome cargo is necessary to ensure safety and efficacy. Future applications may include engineered exosomes with enhanced targeting capabilities, plant-derived formulations with improved penetration, and combination therapies integrating exosomes with established dermatological procedures for improved outcomes across cosmetic, wound healing, and oncological applications. Exosome-based therapies may represent a paradigm shift in dermatological treatment, yet their transition from promising research to mainstream clinical practice hinges on overcoming key technical and regulatory obstacles.</p>","PeriodicalId":13950,"journal":{"name":"International Journal of Dermatology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144325638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathophysiology of HS is multifactorial, with evidence suggesting that the microbiome plays a crucial role in perpetuating inflammation. The persistent nature of HS tunnels, coupled with potential dysbiosis in these lesions, may help explain the recurrent episodes of HS, even with systemic treatment. To explore this further, a literature search was conducted on June 20, 2024. A total of eight studies, involving 418 patients, 632 HS lesions, 360 HS tunnels, and 300 controls, were included. The findings from these studies suggested that HS tunnels are characterized by a polymicrobial microbiome, predominantly dominated by anaerobic bacteria such as Porphyromonas, Parvimonas, Fusobacterium, and Prevotella. In contrast, HS tunnels exhibit a notable reduction in saprophytic species like Cutibacterium acnes and Staphylococcus epidermidis, which are commonly found in healthy skin. Disease stage, as classified by the Hurley system, is the most significant factor influencing the microbiome composition of HS tunnels, with advanced lesions showing a greater presence of dysbiotic and pathogenic flora. Interestingly, no significant differences in bacterial colonization were observed based on variables such as sex, age, smoking status, body mass index (BMI), or anatomical location. Larger biofilms with active bacteria were found in tunnels and anaerobic regions of hair follicles. Overall, these results highlight the distinct polymicrobial, predominantly anaerobic bacterial flora of HS tunnels and the significant reduction in commensal bacteria typically found in healthy skin. This specific microbiome may help explain both the pathogenic characteristics and therapeutic challenges associated with HS tunnels.</p>","PeriodicalId":13950,"journal":{"name":"International Journal of Dermatology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144316860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
