Recent studies show the potential of probiotics to modulate skin microbiome and alleviate acne symptoms. Therefore, this study aimed to consolidate evidence from randomized controlled trials (RCTs) and clinical investigations, evaluating the efficacy of probiotics in acne management. A comprehensive literature search was conducted across PubMed, Scopus, and Cochrane databases using several keywords, such as \"probiotic\", \"microbiome\", and \"acne vulgaris\". Inclusion criteria are RCTs and clinical studies from 2009 to 2024 examining probiotics for acne treatment. Studies were selected, screened, and analyzed based on population, intervention, design, and results. Descriptive statistics were used to summarize study characteristics. Fifteen studies including 811 participants met the inclusion criteria. The studies tested various oral and topical probiotics, including <i>Lactobacillus, Bifidobacterium, Bacillus</i>, and <i>Enterococcus</i> strains, over treatment periods ranging from 4 to 12 weeks. The results showed that probiotics, reduced acne lesions, improved skin barrier function, and decreased inflammatory markers. Both oral and topical probiotics showed potential in balancing skin microbiome and reducing acne severity. Some studies reported outcomes comparable to conventional acne treatments, such as antibiotics and benzoyl peroxide. However, there is variability in individual responses to different probiotic strains, and potential side effects, though rare, have been reported in some cases. Probiotics presented a natural, effective alternative to conventional acne treatment. However, future studies are needed to determine optimal treatment protocols.</p>","PeriodicalId":15846,"journal":{"name":"Journal of Experimental Pharmacology","volume":"17 ","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11727500/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142983696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 100% undiluted liquid smoke accelerated wound healing faster compared to 50% and 25% dilutions. The differences in wound diameters were statistically significant across treatments having a <i>p-value</i> of 0.020 and dose-dependent (<i>p = 0.029</i>).</p><p><strong>Conclusion: </strong>Liquid smoke acceleration of the wound healing process was dose-dependent compared to controls. This dose-dependency indicates that the wound healing effects were probably due to the anti-inflammatory, antioxidant, and antimicrobial activities of the elucidated constituents of Rope bamboo liquid smoke.</p>","PeriodicalId":15846,"journal":{"name":"Journal of Experimental Pharmacology","volume":"16 ","pages":"339-350"},"PeriodicalIF":0.0,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142390995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
