In a prospective multicenter study of 39 patients, dual-frequency noninvasive monopolar radiofrequency (6.78 MHz and 2.0 MHz) applied across dermal and subdermal depths produced clinician-rated Global Aesthetic Improvement Scale scores of 3 or higher in 84.6% of patients at 30 days and 92.3% at 90 days following 2 treatment sessions for facial laxity. Patient satisfaction was similarly high (79.5% at 30 days and 84.6% at 90 days), with mild-to-moderate procedural pain and no persistent adverse events, suggesting the approach may offer a tolerable noninvasive option for short-term improvement in facial skin laxity and lower-face lifting.
