High-Intensity, High-Frequency, Parallel Ultrasound Beams for Cellulite of the Buttocks and Thighs.

BACKGROUND

Ultrasound energy can successfully treat fine lines and wrinkles, as well as lift the eyebrow and submentum. Ultrasound waves of high intensity induce thermal injury in the dermis with subsequent tissue remodeling.

OBJECTIVE

To examine the utility of a novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams to improve the clinical appearance of cellulite on the thighs and buttocks.

MATERIALS AND METHODS

A prospective, multicenter, clinical study investigated this novel ultrasound device using 2 treatments.

RESULTS

Sixty-five subjects completed both treatments. The mean age was 46 years, and 100% were women. Fitzpatrick skin types I to VI were represented. Assessments compared 3-month follow-up with baseline. Two blinded reviewers agreed in identifying pretreatment and post-treatment photographs for 89.2%. For Cellulite Severity Scale rating, there was significant improvement of 1.61 units ( p < .001). For cellulite Global Aesthetic Improvement Scale (GAIS), 89.2% had improvement, with a mean of 0.87 units ( p < .001). For Laxity Scale rating, there was significant improvement of 0.70 units ( p < .001). For skin laxity GAIS, 89.2% had improvement, with a mean of 0.76 units ( p < .001). No device-related adverse events occurred.

CONCLUSION

A novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams can safely and effectively improve the clinical appearance of cellulite on the thighs and buttocks.
