Evaluation of the evidence level for the use of radiofrequency in aesthetic treatments: A systematic review and meta‐analysis

Background Radiofrequency (RF) is a non‐invasive or minimally invasive procedure with a low risk of complications. It has been employed for several aesthetic purposes. Aim This study aimed to conduct a systematic literature review on the use of RF for aesthetic applications and assess the level of accumulated evidence for each condition. Methods Using the MEDLINE/PubMed and EMBASE databases, we searched for articles published from 2009 to 2019 describing the use of RF treatment for aesthetic purposes. Results Our search approach identified 25 randomized clinical trials investigating the efficacy of RF in the following clinical situations: body contour improvement, facial rejuvenation, acne scar treatment, alopecia, and rosacea. There were problems with the quality of the studies, especially regarding selection, performance, and detection bias. Conclusion Our study revealed that RF treatment is potentially promising in all of the evaluated clinical situations; however, we were not able to identify a level of evidence that justifies its use over other therapeutic options currently available on the market.
