Abstract

Background and Objectives: Skin laxity is a common complaint of patients who request a skin rejuvenation procedure. In this study, the clinical effectiveness of high-intensity focused ultrasound (HIFU) for the treatment of facial laxity was evaluated.
Materials and Methods: Nineteen Korean women and one Korean man volunteers were enrolled and first treated with a 4.5-mm, 4-MHz HIFU probe, followed by a 3.0-mm, 7-MHz HIFU probe. A split-face study was performed on one patient. Two blinded, experienced clinicians evaluated pre-treatment and post-treatment (3-months after) paired photographs.
Results: The results revealed that 16 of the 17 subjects (94%) had clinical improvement post-treatment. In a split-face study, the treated site showed excellent improvement compared to the control site. There were no specific side effects noted.
ConclusionIn: In conclusion, HIFU is a useful nonablative method for skin lifting in Asian patients.
