Body Sculpting Clinic. We offer Fat Cavitation, Radio Frequency Skin Tightening and Vacuum Cavitation. Ultrasound fat cavitation uses sound waves to heat up the lypocyte to create liquefation and then removal of the triglycerides (fat cells) in your body. Radio Frequency Skin Tightening works by generating heat to create penetration through the epidermal and dermal layers of skin. This causes tissue retraction to stimulate the function of fibroblast which increases the collogen and skin elastin, leaving the skin tightened and lifted.
