    Abstract

    Systematic review and meta-analysis of oral probiotics for acne.

    Methodology

    Nine randomized studies with 623 patients were reviewed; seven contributed to meta-analysis.

    Key Findings

    No significant effect was seen at four weeks, while 12-week treatment reduced severity and total lesion counts.

    Conclusions

    Oral probiotics may improve acne after 12 weeks, but evidence remains heterogeneous and indirect for hormonal acne.

    Limitations

    Few trials, heterogeneous strains and doses, short-to-medium follow-up, and no hormonal-acne-specific subgroup.

    Supplements Studied

    Probiotics
    Probiotic

    After the 12-week intervention, probiotics significantly alleviated disease severity grading.
