INTRODUCTION: There is a consistent increase in the interest and demand for non-invasive modalities to
improve facial skin laxity and rhytides. Monopolar radiofrequency is one of such non-invasive modalities.
This systematic review aimed to determine the efficacy and safety of monopolar radiofrequency in
improving facial rhytides and skin laxity.

METHODS: Clinical studies that assessed the efficacy of monopolar radiofrequency to address clinically
observable facial rhytides and skin laxity were included. Outcome measures included improvement
in rhytides and skin laxity as documented by patient satisfaction scores, and investigator and third-person
observer ratings based on clinical photographs and clinical scales.

RESULTS: Three studies involving 29 participants were included in this review. All studies reported 25-
50% improvement in facial rhytides and skin laxity. Participants from the three studies were satisfied
with the results. Transient erythema was reported in several patients.

CONCLUSION: Monopolar radiofrequency appears to be beneficial and safe for patients with facial
rhytides and skin laxity. However, the evidence is inconclusive due to problems in the methodological
quality of each trial and the heterogeneity of the studies included in this review.
