Some patients may want to consider fat injections, which use fat harvested from the patient's own body which can then be re-injected to enhance facial fullness, fill creases or build up shallow contours.
Fat injection requires a more extensive procedure than "off-the-shelf" soft tissue fillers.
A "donor area" must be determined (such as the abdomen or buttocks) and liposuction is used to extract the fat. The suctioned fat can then be transferred to the face, as a graft.
The grafted fat then has to redevelop a blood supply in order to survive. About 50% of the fat injected will survive, and the surviving fat will last forever.
