Abstract
Radiofrequency microneedling (RFMN) treatment is the latest generation of fractional skin rejuvenation methods. To evaluate the efficacy, safety, tolerability and patient satisfaction of RFMN treatment for skin rejuvenation of the lower face and neck area. A prospective, intraindividual, controlled study. Subjects were treated with a fractional insulated RFMN system with 1 to 3 sessions at intervals of 4 to 12 weeks. Follow-up visits were scheduled on Day 90 and 180 posttreatment. Outcome was assessed by volume analysis of standardized 3-dimensional imaging, and validated clinical scales were rated by the physician, a blinded investigator, and patients. Thirty patients (mean age 55.5 years, Fitzpatrick skin type I-IV) were included. Mean submental volume difference was -4.72 cm3 (±10.07 cm3; range -26.65 cm3 to +16.01 cm3). Physician, blinded investigator, and subjects rated the clinical outcome as highly improved. Mean pain intensity was 5.61/10 on Numeric Rating Scale. Beside slight swelling and redness, no relevant downtime has been observed. Fractional RFMN treatment is a safe and effective technique for rejuvenation of the lower face, jawline, and neck region. Sufficient pain management should be provided. Data indicated low to no downtime and high patient satisfaction.
