Liposuction is one of the most commonly performed cosmetic procedures in the United States. Liposuction is a surgical procedure intended to sculpt the body and remove unwanted fat deposits (lumps and bulges). Although no type of liposuction is a substitute for dieting and exercise, liposuction can remove stubborn areas of fat that do not respond to traditional weight loss methods. Liposuction may be performed on the abdomen, hips, thighs, calves, arms, buttocks, back, neck, or face.
