Body contouring for fat and muscle in aesthetics: Review and debate.

The recent demand for noninvasive fat reduction and muscle toning has generated the need for a variety of noninvasive body contouring devices, including cryolipolysis, radiofrequency, focused ultrasound, laser energy, and high intensity focused electromagnetic energy. Many of the recent technologies are still relatively new, and clinical trials are limited. There is also a lack of comparison between modalities, which makes it difficult for practitioners to select the best treatment option for patients. We review the currently available treatment modalities and offer relevant insights.
