Autologous Fat Grafting
Human fat harvested from a patient’s own body can be re-injected to enhance facial fullness and smooth lines. Autologous fat grafting or micro-lipoinjection involves extracting fat cells from the patient’s abdomen, thighs, buttocks or elsewhere and re-injecting them beneath the facial skin. Fat is most often used to enhance facial fullness, add volume to cheeks, nasolabial folds or marionette lines, to correct skin depressions or indentations, and to enhance the lips. Fat injection requires a more extensive procedure than other injectable fillers because liposuction is required to extract the fat prior to injection. The fat is withdrawn using a syringe with a large needle or cannula. The fat is then prepared, isolated, and injected into the recipient site. Results can be variable because the fat cells are sensitive to handling and, depending upon the area treated, not all fat survives transfer. The fat that does survive grafting may last long periods. Allergic reaction is not a factor for fat grafting because it’s harvested from a patient’s own body. However, there is still a small risk of infection and other infrequent complications.
