Fat may be taken from almost any part of the body to augment the buttocks (Brazilian butt lift). The most common places are from the sides and lower back, and from the abdomen. These areas not only give you great fat to process for transfer to the buttocks, they also allow the plastic surgeon to reshape the buttocks. Taking away the excess fat from the hips and just above the buttocks makes it look better even before the fat is placed!
Thihg fat, arm fat and even upper back fat may be used to transfer to the buttocks.
