3-In-1 40K Ultrasonic Cavitation Machine will provide you with the most effective at-home solution to burn stubborn fat, remove cellulite, and tighten skin from any area of your body. This machine works with High-intensity, targeted ultrasonic (or ultrasound) waves vibrate the fat cells, creating air bubbles that expand and burst, forcing the adipose membranes (fat cells) to burst, releasing free fatty acids and glycerol. Water-soluble glycerol is then used to generate energy in the body, whereas the fatty acids get absorbed by the liver like any other fatty acids you get with your food. During cavitation only fat tissues are affected, because they have a much weaker membrane, leaving other tissues completely unaffected. Transmits 40kHz targeted ultrasonic waves to break down the fat cells under the skin. Best for removing fat overall. This head uses radio frequency energy pulses that help speed up the lymphatic system to help with the broken down fat cells. Also stimulates collagen growth in the skin to help improve sagging skin and remove wrinkles. Best used for smaller and more sensitive areas such as the face. Similar to the Tripolar head except more powerful. Good for firming and tightening skin in larger areas, and reducing cellulite. Also helps the lymphatic system get rid of the broken down fatty cells. Both RF heads have an infrared light to help speed up the treatment process. Infrared light is proven to help stimulate blood flow and rejuvenate the skin.
