A Prospective, Randomized, and Split-Face Study to Evaluate the Efficacy and Safety of Focused Ultrasound for Facial Skin Laxity

The goal of this clinical trial is to learn if focused ultrasound can improve facial skin laxity in adults. The main questions this study aims to answer are: 1. Does focused ultrasound treatment lead to clinically meaningful improvement in facial skin laxity compared with baseline assessments? 2. What treatment-related adverse events occur following focused ultrasound treatment, and how frequently and severely do they occur? Researchers will also compare outcomes between the two sides of the face treated with different focused ultrasound hand-pieces within the same participants to explore potential differences in clinical response and safety using a randomized split-face design. Participants will: Receive a single session of focused ultrasound treatment applied to both sides of the face. Undergo standardized clinical assessments, imaging evaluations, and patient-reported outcome measures at baseline and during follow-up visits. Be monitored for treatment-related adverse events throughout the study period.
