Study Finds High-Intensity, Parallel Beam Ultrasound-Based Skin Tightening Effective For Improving Upper Arm Skin Laxity, Crepiness

A study published in Dermatologic Surgery evaluated and compared the efficacy of high-intensity, parallel beam ultrasound-based skin tightening (HIUS) device with microfocused ultrasound with visualization (MFU-V) for the improvement of upper arm skin laxity and crepiness. 

The prospective, single-center, blinded, split-body, randomized clinical study titled, “A Single-Center, Blinded, Split-Body, Randomized Clinical Trial of High-Intensity, Parallel Ultrasound Beams Versus Microfocused Ultrasound with Visualization for the Treatment of Upper Inner Arm Skin Laxity,”investigated HIUS and MFU-V for the improvement of upper arm skin laxity and crepiness. 

Fourteen subjects received a single treatment to the upper arms. Assessments compared day 30 and day 90 follow-up visits with baseline. HIUS was found to be as effective as MFU-V in improving arm laxity and crepiness. Both investigators and subjects rated improved arm laxity and crepiness at day 90. 

Most subjects reported satisfaction with the improvement in arm laxity and crepiness. There was no statistically significant difference in pain scores between the HIUS and MFU-V groups. The MFU-V treatment required more time to perform than the HIUS treatment. 

Investigators concluded high-intensity, parallel beam ultrasound-based skin tightening was effective and delivered results with high patient satisfaction for improving upper arm skin laxity and crepiness.
