Clinical evaluation of non-ablative radiofrequency facial rejuvenation

Abstract

OBJECTIVE: To evaluate the clinical efficacy of non-ablative cutaneous radiofrequency (RF) facial rejuvenation. DESIGN: Prospective study with longitudinal follow-up of a validation cohort set in an urban, private practice of an ambulatory facial plastic surgery center in southern California. METHODS: A consecutive sample was enrolled of 35 healthy adults with moderate facial aging, manifested by skin laxity, rhytids, and ptosis (brow, midface, jowls). Following intravenous sedation anesthesia, the study area was treated with 115-144 J/cm2 using the non-ablative RF device (ThermaCool TCTM). The main outcome measures were the objective measurement of brow height, investigator evaluation of skin parameters, a patient satisfaction questionnaire, and standardized photography, at fixed time intervals. RESULTS: At 12 weeks, a statistically significant increase in mean vertical brow height of 1.6-2.4 mm was observed in patients treated exclusively with the RF device (p<0.0001). All skin parameters (laxity, wrinkles, clarity, pore size) were improved. Complications and side effects were minimal. Patients were uniformly satisfied. CONCLUSIONS: The ThermaCool TC RF system represents a promising non-invasive method of obtaining moderate facial rejuvenation in the appropriately selected patient. Long-term results are pending.
