Abstract
Introduction: Monopolar radiofrequency (MRF) is a valuable modality for tightening and contouring mild-to-moderate facial skin laxity. Few studies have evaluated new-generation MRF devices for lower facial laxity in Asians. This study aims to evaluate the efficacy and safety of MRF for treating lower facial laxity in Asians. Methods: This prospective cohort study enrolled 30 volunteers with Fitzpatrick Skin Types III–V and mild-to-moderate skin laxity. Subjects received a single MRF treatment. Self-assessments and adverse events were recorded. Two blinded dermatologists graded improvements (6-point scale) after treatment and 1, 3, and 6 months later. Results: All subjects completed the study. Treatment energy levels ranged from 2 to 4. The average number of shots was 412 ± 49, delivered in 3–4 passes with 15–30% overlap. All patients reported improvement in lower facial laxity immediately after treatment. Most patients had mild-to-moderate improvement over the 6-month follow-up. Continuous improvement was observed at the 1-, 3-, and 6-month follow-ups (P < 0.01). Significant improvement was seen at the 6-month follow-up compared with the 1-month follow-up (P < 0.01). Subjects tolerated the procedure well: the average pain score was 3.13 out of 10, and no serious adverse events were observed. Conclusions: The new-generation MRF device we tested was effective and safe for mild-to-moderate lower facial laxity in Asian skin. The latest MRF technology offers improved safety to prevent complications. Appropriate patient selection, setting, and protocols are mandatory to achieve optimal clinical outcomes.
