Ultrasonic Cavitation Learn What It Is, How It Works

How does ultrasonic cavitation work? During an ultrasonic cavitation procedure, noninvasive machines target specific body areas with low-frequency sound waves (they're what put the "ultrasonic" in "ultrasonic cavitation") and, in some cases, light suction. This process heats and vibrates the layer of fat cells below the skin's surface.
