Fractional radiofrequency treatment in acne scars: Systematic review of current evidence.
Fractional radiofrequency (FRF) is renowned for its use in cosmetic dermatology, with regard to the treatment of rhytides, striae, scarring and cellulite. We have systemically analysed its evidence for the use of FRF in acne scars. Our search identified 15 articles, one single-blinded randomised controlled trial, two split-face trials and thirteen prospective clinical studies, mostly single-centred. Case reports were excluded. In total 362 patients were treated. The longest follow-up was for 210 days, and on average the follow-up was for three months, varying between one and seven months. This review has found that there are many small studies showing promising results for the use of FRF in acne scars, either as an adjunct or more importantly as the sole treatment. There is however a need for larger trials against ablative and non-ablative lasers, in order to affirm the evidence present already. This is the first systematic review on the use of FRF in acne scars.
