The efficacy and safety of the high-intensity parallel beam ultrasound device at the depth of 1.5 mm for skin tightening

Abstract

Background: High-intensity parallel beam ultrasound (US) is a novel device equipped with Synchronous Ultrasound Parallel Beam (SUPERB) technology applied in anti-aging treatment. The system is aimed at pathways stimulating neocollagenesis and neoelastinogenesis in the dermis leading to skin tightening and rejuvenation. Aims: Evaluate the efficacy and safety of the high-intensity parallel beam US device at the depth of 1.5 mm for skin tightening treatment. Methods: Thirty-six participants were enrolled in the study. Digital photographs and Antera 3D photographs were taken at baseline, 1 and 3 months post-treatment. The depression volume of nasolabial folds (NLFs) and marionette lines (MLs) in each visit was evaluated using Antera 3D imaging program. Pain was evaluated by pain measurement scales immediately after treatment. Any procedure related side effects were documented and examined. Results: Post-treatment results were compared to the baseline; statistically significant mean depression volume (MDV) change of NLFs and MLs were found at 1 and 3 months post-treatment. No significant MDV change from 1 to 3 months post-treatment could be demonstrated. The mean pain score was 6.64 on a 0–10 scale. No adverse events were reported. Conclusions: Our study demonstrates that the novel high-intensity parallel beam US device is clinically safe and effective for skin tightening in the lower face area. We noticed a reduction in NLFs and MLs in more than 60% of our participants already as early as 1 month post-treatment.
