A fat transfer, or fat injections, involves moving fat from one region of the body and re-injecting or implanting it into another. This procedure can be done with a syringe, liposuction, or even surgically. The transferred fat can be used to enhance facial features, including the lips, repair and smooth aged hands, and more. Usually the fat is taken from the lower stomach, the inner thighs, or the inner knees. Initially the area may appear swollen but after some time the excess fat is reabsorbed and the body takes on its new improved shape. Fat injections generally have long lasting results.
