SUMMARY

Abstract
The lower one-third of the face and neck has historically been difficult to treat with noninvasive technologies, while traditional facelift often struggles with recurrent laxity. This prospective, multicenter IRB-approved study evaluated a handsfree thermoregulated bipolar RF device (Evoke, InMode) for facial and submental contouring. Forty patients were treated using cheek and chin applicators at 42–43°C, with treatment times averaging 41 minutes. Outcomes included blinded assessments, 3D volumetric imaging, and patient satisfaction.

Conclusion
Results showed significant volumetric reductions in both cheeks and submental areas (−3.2 cm³ and −4.1 cm³ at 6 months), high patient satisfaction (76–85%), and consistent investigator-rated improvements. Discomfort was minimal, and no serious adverse effects occurred. The study concludes that Evoke provides a safe, effective, and reproducible solution for lower face and neck tightening, advancing the field of noninvasive RF contouring.
