Safety and efficacy of high-intensity focused ultrasound for treatment of periorbital, perioral, and neck wrinkles: Prospective open single-center single-arm confirmatory clinical trial

초록

Periorbital, perioral, and neck wrinkles are one of the most common concerns of aging skin. We evaluated the efficacy and safety of high-intensity focused ultrasound (HIFU) device with a 5.5-MHz transducer and a 2.0-mm focal depth for improving periorbital, perioral, and neck wrinkles. A total of 102 participants were enrolled, and 34 each were assigned to the periorbital, perioral, and neck groups. All subjects were treated with HIFU three times at 2-week intervals at the corresponding treatment site. Objective measurements and clinical evaluations were performed at 10 and 16 weeks after treatment. Based on the primary efficacy evaluation, the mean Cutometer R7 value was significantly increased at 10 weeks post-treatment compared to baseline in all treated groups. In addition, all other Cutometer values, PRIMOS and Antera 3D camera evaluation results, classification of wrinkle assessment results, and Subject Global Aesthetic Improvement Scale also showed that the periorbital, perioral, and neck wrinkles were significantly improved at 10 and 16 weeks post-treatment. No permanent adverse effects were observed during the follow-up period. HIFU treatment using 5.5-MHz transducers (2.0-mm focal depth) could be an effective and safe treatment modality for the treatment of periorbital, perioral, and neck wrinkles.
