Body contouring after major weight loss improves the shape and tone of your underlying tissue that supports fat and skin and removes excess sagging fat and skin.
Following weight reduction surgery, or any substantial amount of weight loss, the skin and tissues often lack elasticity and cannot conform to the reduced body size. As a result, skin that has been severely stretched now is unsupported:
The result is a more normal appearance to the body, with smoother contours. This is, in essence, the final phase of your total weight loss experience.
