In the medical world, the fat injection procedure is known as autologous fat transplantation or microlipoinjection. It involves extracting fat cells from the patient’s abdomen, thighs, buttocks or elsewhere and reinjecting them beneath the facial skin.

Fat is most often used to fill in “sunken” cheeks or laugh lines between the nose and mouth, to correct skin depressions or indentation, to minimize forehead wrinkles and to enlarge the lips. Fat injections are also used for buttock enhancements and to fill in any depressed or scarred areas of the body.
