Fat TransferIn 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 or to correct skin depressions or indentations. The procedure: After both the donor and recipient sites are cleansed and treated with a local anesthetic, the fat is withdrawn using a syringe with a large-bore blunt needle attached to a suction device. The fat is then prepared and injected into the recipient site. Sometimes an adhesive bandage is applied over the injection site. As with collagen, "overfilling" is necessary to allow for fat absorption in the months following treatment. This overcorrection of newly injected fat may temporarily make the face appear abnormally puffed out or swollen. |
