ABSTRACT: Background: High-intensity focused ultrasound (HIFU) has been
introduced to improve skin laxity in recent years. 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.
