Fat transfer, also called autologous fat transplantation or micro-lipoinjection, is a minimally invasive cosmetic procedure that removes unwanted fat from one area of the body and places it into another area of the body, usually to improve the appearance of the new area. Fat is the natural filler for the facial rejuvenation and breast or buttock augmentation. Fat transfer can correct aging in the hands and post-surgical and post-traumatic defects. A major advantage of fat transfer is that patients can never have an allergic reaction since the fat used is taken from their own bodies.
Autologous fat transfer involves gently removing fat from body regions with localized fat deposits. Under local anesthesia, a small ultrasound probe is inserted to liquefy the fat cells. Once the fat has been dissolved, it is harvested through a gentle suction process. The harvested fat is then injected into the areas of depressions, irregularities, and asymmetries.
