While a tummy tuck is very effective at producing a flat tummy, it can result in a significant scar, possibly extending from hip to hip. Liposuction is a procedure that can help sculpt the body by removing unwanted fat from specific areas, including the abdomen, hips, buttocks, thighs, knees, upper arms, chin, cheeks and neck.
