Ultrasonic cavitation is a weight-loss treatment that uses low-frequency sound waves to burst fat cells, which may result in lost inches on the treated areas and (ultimately) a slimmer figure. It's been growing in popularity over the last few years because while traditional liposuction requires an invasive procedure to remove fat, this procedure doesn't.

Ultrasonic cavitation is a simple procedure that relies on sound waves to flush fat from the body instead of intensive surgery.

During an ultrasonic cavitation procedure, noninvasive machines target specific body areas with low-frequency sound waves (they're what put the "ultrasonic" in "ultrasonic cavitation") and, in some cases, light suction. This process heats and vibrates the layer of fat cells below the skin's surface. The pressure eventually causes the fat cells to liquefy and release their contents into the bloodstream. Proponents of the procedure believe that the body is then able to process these fatty acids through its proverbial waste-disposal plant: the lymphatic system.
