BodyTite can be performed alone or combined with liposuction to address sagging skin on targeted areas of your body including your abdomen, neck, upper arms, thighs, knees, breasts, and buttocks. BodyTite uses probes connected to a handpiece that enables your doctor to apply radiofrequency waves that liquefy fat cells. That causes collagen fibers in your skin to contract and tighten. It also boosts collagen production, further contributing to a smooth, contoured appearance. If your surgeon combines BodyTite with liposuction, a small tube called a cannula is used to suction out excess fat.
