The 3-in-1 40k ultrasonic cavitation machine is a multi-functional beauty device that combines two different technologies: ultrasonic cavitation, radio frequency (RF) treatment. Ultrasonic cavitation uses low-frequency sound waves to target and break down localized fat deposits in the body. Radiofrequency therapy emits heat that promotes collagen production and tightens the skin. The machine is designed to provide non-invasive body sculpting, fat reduction and skin tightening treatments.
