A clinical evaluation of noninvasive and contactless radiofrequency technique in the treatment of abdominal fat.

Abstract

There is an increasing demand for fat reduction and body contouring procedures. Noninvasive radiofrequency devices have been used to tighten skin and treat cellulite, but there are few studies confirming their efficacy for abdominal fat reduction. This study explored the effects of four noninvasive radiofrequency (RF) treatments on abdominal fat in Asian subjects, evaluating body weight, body mass index (BMI), and waist circumference. In this study, 16 patients with abdominal obesity were treated four times with a noninvasive and contactless selective RF device (VANQUISH ME™, BTL Aesthetics). Treatments were 7days apart and lasted 45min each. The BMI and circumference of the upper, middle, and lower abdomen were measured at baseline and after each treatment. There were statistically significant reductions in BMI and abdominal circumference in all 16 patients (P<.05). Most patients only experienced a slight abdominal heat sensation and minimal body sweating during the treatment, and no adverse reactions were observed after the treatment. The noninvasive and contactless selective RF technique was effective and safe in reducing fat, BMI, and abdominal circumference.
