Today, different kinds of non-invasive body contouring modalities, including cryolipolysis, radiofrequency RF , low-level laser therapy LLLT , and high-intensity focused ultrasound HIFU are available for reducing the volume of subcutaneous adipose tissue or cellulite.
Each procedure has distinct mechanisms for stimulating apoptosis or necrosis adipose tissue. In addition to the mentioned techniques, some investigations are underway for analyzing the efficacy of other techniques such as whole body vibration WBV and extracorporeal shockwave therapy ESWT. In the present review the mechanisms, effects and side effects of the mentioned methods have been discussed. The effect of these devices on cellulite or subcutaneous fat reduction has been assessed.
We searched pubmed, google scholar and the cochrane databases for systemic reviews, review articles, meta-analysis and randomized clinical trials up to February We included seven reviews and 66 original articles in the present narrative review.
Six of the articles evaluated combination therapies and seven compared the effects of different devices. Some of the noninvasive body contouring devices in animal and human studies such as cryolipolysis, RF, LLLT and HIFU showed statistical significant effects on body contouring, removing unwanted fat and cellulite in some body areas. However, the clinical effects are mild to moderate, for example 2 - 4 cm circumference reduction as a sign of subcutaneous fat reduction during total treatment sessions.
