Efficacy and Safety of Radiofrequency and Focused Ultrasound in Facial Rejuvenation: A Single-Center, Single-Blind, Non-Randomized Prospective Trial.

ABSTRACT:

Background

Although both radiofrequency (RF) and focused ultrasound (FU) are commonly used non-invasive skin-tightening methods, comparative studies between the two methods are lacking.

Objective

To study and compare the efficacy and safety of RF and FU in facial rejuvenation.

Methods

We recruited 36 patients to receive a single treatment: the RF group (n = 21) and the FU group (n = 15). Every participant was evaluated on baseline (T0), 1-month follow-up (T1) and 3-month follow-up (T3). Three blinded dermatologists used the FLR scale, Modified Fitzpatrick Wrinkle Scale (MFWS), and Allergan Skin Roughness Scale to assess facial wrinkles. Safety profiles were recorded, and subjects completed questionnaires to provide subjective evaluations.
