Fat grafting is also called free fat transfer, autologous fat transfer/transplantation, liposculpture, lipostructure, volume restoration, micro-lipoinjection and fat injections.
This is a procedure which removes surplus fat cells from one area of the body and then re-implants it where needed.
Fat grafting fills facial features with a patient's own fat. The fat used for fat transfer is extracted from part of your body like the abdomen or thighs and injected into another area that requires plumping.
The advantage of fat grafting is that the fat comes from your own body, so you cannot develop an allergic reaction unlike other external implant substances that are introduced into the body. Your body naturally accepts the injected fat.
Fat grafting can been used for correcting or improving:
Fat grafting lasts longer in larger areas of non-movement, so while it is successful for the correction of grooves under the eyes and sunken cheeks, it may not be as successful for creating fuller lips. Fat grafting can also correct aging of the hands where the natural tissue is lost between the bones.
Fat grafting is not recommended for breast augmentation as the grafted fat can later make it difficult to detect breast cancer.
Fat grafting is performed in your doctor's rooms on an outpatient basis. There are basically 3 parts to the procedure.

After the procedure, avoid massage and excessive facial movement, as this will stop migration of the fat away from the desired areas of treatment. Ice compresses may be used for 24-48 hours to minimise inflammation.
The doctor will schedule to see you about a week after the procedure to check both the donor and recipient sites. A follow-up appointment 6-8 weeks later should see most of the swelling resolved and early results assessed. A repeat procedure may need to be performed if the desired outcome has not been achieved but this should not be within 3 months of the first graft.
How much of the graft survives and for how long is currently unknown. Over the first few months your body will resorb about 65% of the fat. The remaining 35% will usually stay in place. It appears that the amount resorbed by the body and ultimately the longevity of the graft is highly dependent on the technique used in grafting. Newer techniques are being developed to increase the longevity. For longer lasting results, patients may receive 3 or 4 treatments over a period of 6 months to a year.
A moderate amount of swelling is expected after the fat graft. This is usually evident for 2 weeks after the procedure. Some bruising may also be apparent.
Some complications of fat grafting include:
