Body shaping with acoustic wave therapy AWT(®)/EPAT(®): randomized, controlled study on 14 subjects.

Author information

SKINPULSE Dermatology & Laser Centres, Geneva, Switzerland.



Reduction of localised adiposities by non invasive means is a very frequent request among the female and male population.


The objective of this study is to demonstrate the efficacy and safety of AWT(®), combining two different mechanical waves, planar AWT and radial AWT during the same session, in volume reduction of saddle bags in women.


Treatment was performed on the saddle bag areas of 14 female patients, with the CELLACTOR(®) SC1 (Storz Medical AG, Tägerwilen, Switzerland) using extracorporeal pulse activation technology, EPAT(®). This device includes two handpieces, the C-ACTOR(®) and the D-ACTOR(®). Within 4 weeks, eight AWT(®) treatment sessions have been performed with both applicators. Follow-up visits were performed 1, 4 and 12 weeks after the last treatment.


Measurements with the ultrasound system clearly demonstrate a significant diminution in the subcutaneous fat layer thickness and a reduction of the averaged circumference of thighs.


This study, although performed on a small number of patients, tends to show the safety and efficacy of AWT(®) in treating localized fat areas in a non-invasive way. There is also an additional benefit for patients in reducing the cellulite appearance and improving the skin firmness at the same time by using AWT(®).
