If skin is already sagging or loose in a certain area, liposuction will not improve its appearance. Cellulite and stretch marks are also not likely to improve significantly, although there may be a slight smoothing of the area, depending on the firmness of your skin. The elasticity of a patient’s skin is a key factor in how the skin will look after the procedure. If skin is elastic and muscle tone is good, the skin will conform well to the new body shape. With skin that has been stretched and is less elastic, folds of skin may be apparent after removal of fat.
