Fractional radiofrequency (FRF) technology has been shown in clinical studies to improve skin laxity, and to treat various skin conditions related to aging and alternate collagen structures such as rhytids.

The objective of this clinical study was to evaluate the safety and performance of FRF (up to 124 mJ per pin) for the treatment of facial rhytids, emphasizing the upper lip and perioral areas.

Enrolled subjects received a series of 3 FRF treatments to the full face, 3 to 5 weeks apart. Immediately after treatment, the subjects were given a scale to assess pain and tolerability of the treatment.

Subject satisfaction questionnaires were completed at follow-up visits at 6 and 12 weeks post final treatment.

Before and after photographs were graded for change by three blinded evaluators using the Fitzpatrick Wrinkle and Elastosis Scale (FWES) and the Global Aesthetic Improvement Scale (GAIS).
