Abstract
|
|
|
Background: High-intensity focused ultrasound (HIFU) and monopolar radiofrequency (RF) are used for facial rejuvenation. Both modalities are popular non-invasive skin tightening and wrinkle reduction procedures and are implemented autonomously or in combination. However, their synergic effectiveness remains to be determined.
Method
s: Thirty-six patients treated for skin wrinkles by HIFU or HIFU plus monopolar thermal RF between August 2021 and August 2023 were enrolled in this study. An automatic skin diagnosis system was used to evaluate treatment efficacies, and a blinded clinician assessed clinical photos. Safety and patient satisfaction were also investigated.
Results: Twenty patients received HIFU monotherapy (Group A) and 16 simultaneous HIFU plus monopolar RF (Group B). An automatic skin analysis system showed that both techniques achieved significant wrinkle improvement. However, Group B had better clinical assessment and patient satisfaction scores. Observed adverse effects, which included erythema and swelling, were mild and self-limiting.
Conclusion: Combined HIFU and RF constitute a safe non-invasive procedure that effectively improves facial wrinkles and skin laxity.
