The treatments by cooling the fatty tissue is called cryolipolysis. There are several devices on the market to perform these treatments. Cryolipolysis freezes the lipids in fat cells. Radiofrequency releases energy with controlled heat technology. Heating slowly dissolves the fat cells. Echo, sound waves or ultrasound use high-intensity, focused ultrasonic waves (sound waves) with the mechanical destruction of fat cells without heating or cooling as the goal.
With these techniques, the goal is to break up the fat cells without trauma or injury to surrounding tissue (especially the skin). Through this technique, the fat layer is slowly reduced slightly, over the course of 2 to 6 months after the procedure.
All of these treatments are non-invasive: they work from outside the body, through the skin. This makes these methods very suitable for people who are not eligible for liposuction treatment due to health reasons or medication use, or who are not comfortable with liposuction.
