Body fat makes excellent soft tissue filler material. Fat injection (also called autologous fat transplantation) transfers fat from one part of the body to another to recontour the face; diminish nasolabial folds (smile lines), provide definition to areas like the cheeks and chin and increase volume of the lips. It can also be used to fill out depressed scarred areas on any part of the body. Fat injection is not permanent, and may require an effective maintenance program.
Human fat, taken from your own body can be used as an injectable filler. Prior to injection, fat must be “harvested” or extracted from your tummy, thighs or buttocks using liposuction techniques. For this reason, fat injections are a more involved procedure then injections with pharmaceutical fillers. Once injected into soft tissue, the fat must develop a blood supply to “take” or survive and provide a long-term correction, although some of the fat cells will be naturally absorbed. The remaining fat and the enhancement achieved is considered permanent, although it will diminish naturally with age. Extracted fat can also be frozen for your own future treatment. However, the results from frozen fat are not as favorable as fat that is injected in the same treatment session during which it is harvested.
