Abstract

Background
High-intensity focused ultrasound (HIFU) is a widely used procedure for skin rejuvenation because it targets only the superficial musculoaponeurotic system layer with coagulated thermal energy. However, its long procedure time is inconvenient for both the patient and the operator. The purpose of this study was to investigate the clinical effects of 2-line HIFU.
Methods
Between August 2021 and September 2022, patients with sagging and loose facial skin were treated with a 2-line HIFU (10thera ® ) following the manufacturer’s recommended protocol. We evaluated patients using an automatic skin diagnosis system at the pretreatment stage and about three months after treatment.
Results
All patients were treated using the 2-line HIFU. Five patients were lost to follow-up. The median procedure time was 14 minutes. The mean skin grade was 17 at pretreatment and 14 at posttreatment, showing a significant (p < 0.01) difference between the two.
Conclusion
This study suggests that the 2-line HIFU can improve wrinkling and sagging of an aging face. It is believed that the shortened treatment time would improve the satisfaction levels of both the operator and the patient.
