Research: WINTER,

Listed in Issue 189


WINTER, Department of Obstetrics and Gynecology, University of California at Irvine, CA, USA. evaluated the performance of a high-power device (50 W as opposed to 25 W), combining these energies for reshaping and improvement of skin texture/laxity in postpartum women.


Non-invasive body contouring is an increasingly popular aesthetic application. Previous data support the efficacy of combined radiofrequency, infrared and skin manipulation for cellulite treatment.


Twenty women received five weekly treatments to the abdomen, buttocks and thighs with the VelaShape system. We followed up each patient's weight and nutritional habits. Outcome was assessed using reproducible circumference measurements, digital photography, the physician's scores of cellulite and improvement as well as patient satisfaction. Safety was evaluated by recording subjects' comfort and tolerance.


The overall mean circumferences reduction was 5.4 +/- 0.7 cm (p < 0.001). Significant (p < 0.02) improvement in skin laxity and tightening was noted by both the physician and patients. Treatments were well tolerated with no major safety concerns (one purpura, one mild burn).


The enhanced capabilities of the evaluated system enabled significant results in fewer and shorter sessions without compromising patients' safety or comfort. These data suggest that postpartum reshaping via circumferential reduction and skin laxity improvement can be effectively and safely achieved using a high-energy combination of radio frequency, infrared and mechanical manipulation.
