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

Abstract

Background 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. Objective 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. Methods 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 7 days apart and lasted 45 min each. The BMI and circumference of the upper, middle, and lower abdomen were measured at baseline and after each treatment. Results 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. Conclusion The noninvasive and contactless selective RF technique was effective and safe in reducing fat, BMI, and abdominal circumference.

Effects of microwave technology on the subcutaneous abdominal fat and anthropometric indices of overweight adults: A clinical trial

“…In another study, Winter performed a prospective self‐controlled study and observed a reduction in circumference, and skin laxity improvement could also be effectively achieved using a combination of RF, infrared, and mechanical manipulation 27 . Our findings are consistent with the results obtained by Qin et al, which indicated that non‐invasive and contactless selective RF methods were effective and safe in the reduction of fat, BMI, and abdominal circumference 28 …”

“…27 Our findings are consistent with the results obtained by Qin et al, which indicated that non-invasive and contactless selective RF methods were effective and safe in the reduction of fat, BMI, and abdominal circumference. 28 Fajkošová et al reported that a selective RF system is a painless, safe, and effective treatment for body contouring and circumferential fat. 29 Several other studies have also confirmed the effectiveness of RF as a non-invasive technique in the reduction of subcutaneous fat in the thighs and buttocks.…”

Noninvasive lipolysis modalities in aesthetic medicine

“…Based on the review of evidence presented earlier, radiofrequency is most used in the abdominal region and results in a statistically significant decrease in abdominal fat thickness. 32,34,36,[38][39][40] These outcomes continue to improve with each treatment and persist until the last follow-up appointment. Additionally, this method has shown to successfully reduce fat volume in the lower face, both in terms of submental circumference and fat thickness.…”

“…The main side effects of radiofrequency treatment were heat sensation, mild pain or discomfort and local skin irritation, that is, erythema, warmth, tingling or oedema. [32][33][34][37][38][39][40] interruption of treatment 34 and one participant developed a palpable nodule. 40 All adverse reactions were transient and resolved without intervention.…”

“…40 All adverse reactions were transient and resolved without intervention. [32][33][34][37][38][39][40] No serious or long-term complications were reported. [32][33][34][36][37][38][39][40] In addition, there were no cases of PAH documented in of the included studies.…”
