Ultrasonic cavitation machines are non-invasive and pain-free devices that give you a toned and sculpted body. These machines use high-frequency sound waves that penetrate your skin to break down the fat cells.When the cavitation head is rubbed on your skin, the ultrasonic waves will break the fat cells beneath the skin’s surface. Once the fat is released, it decomposes and is excreted naturally by the liver through the lymphatic system.The machine creates air bubbles between the fat cells, and these bubbles break down the cells with the pressure.
