Autologous fat transfer, also called fat grafting or fat injection, is a plastic surgery procedure in which fat cells are transferred from one part of the body to another. Fat cells are mostly harvested from the areas such as the abdomen, buttocks or tights and injected into the areas which lack volume. Autologous fat grafting plays a significant role in facial rejuvenation. Traditional approaches to facial rejuvenation involve subtractive surgical techniques in which the surgeons focus on the removal of skin, muscle, or fat. Modern approaches, on the other hand, focus on filling the “empty” facial compartments, mainly through fat grafting.
