However, very few studies have evaluated the safety and effectiveness of HIFU in Chinese populations. Methods: In the study, 30 Chinese participants underwent HIFU (Bolida, Inc., Changsha, China) rejuvenation between February 1, 2022, and September 30, 2022. There were three different focal depths used depending on the area where shots were captured (4.5 mm, 4 MHz;3 mm, 7 MHz;1.5 mm, 7 MHz). After 3 months and 6 months of treatment, efficacy and safety were assessed by quantitative analysis. Results: Patients were satisfied with the clinical effects of HIFU rejuvenation after one session. In terms of effectiveness, HIFU was most successful in areas around the jawline, cheek, and perioral. In four cases, erythema was observed, in two cases, swollen gums were seen, but all of these effects were transient and mild. Conclusion: Bolida system can be safe and effective for facial tightening, additionally, they are most effective for jawline, cheek, and perioral improvements. In clinical practice, the Bolida system can be recommended as a reliable treatment option. .展开更多
