Fat grafting to the face, also called autologous fat transfer, is a procedure that can be used to add fullness and volume to the face. Fat is removed from another area of the body, usually the thighs or abdomen, via liposuction and then injected into the face. This can help to improve the appearance of wrinkles, scars, and sunken areas.
One of the advantages of fat grafting is that it uses your own natural tissue so there is no risk of rejection or allergic reaction. However, one potential downside is that the results are not always permanent. In some cases, the grafted fat may be reabsorbed by the body over time or it may simply shrink back down to its original size.
