4 in one 40k cavitation slimming instrument adopts the latest scientific and technology that can provide effective treatments for stubborn cellulite and orange peel fat.

The ultrasound waves are conducted through the skin, penetrate directly into the adipose tissue and break it up into small pieces causing micro-bubbles which turn fat into a liquid substance (this phenomenon is called “cavitation”).
