Fractional Radiofrequency Microneedling as a Monotherapy in Acne Scar Management: A Systematic Review of Current Evidence.

Fractional radiofrequency microneedling (FRM) is a popular, minimally invasive skin rejuvenation modality for treating acne scarring. In this study, we aimed to systematically evaluate the current literature on the efficacy and safety of FRM as a monotherapy to treat different types of facial acne scarring. We systematically reviewed all available literature on FRM techniques used for acne scarring by searching the PubMed and EBSCO databases up to July 2024. 16 studies involving 481 patients, comprising six prospective studies, six randomized clinical trials, three retrospective studies, and one comparative trial, were included. FRM is likely an effective treatment for acne scarring when used as a monotherapy. Further randomized controlled trials are needed to establish appropriate treatment parameters.
