Adipocytes selected from autologous fat are living autologous tissues. Therefore, after being transplanted to the face, they can get sufficient blood supply in a new place and live permanently to maintain their volume. In the process of facial filling with autologous fat, some adipose tissue without blood supply will be absorbed. Generally speaking, 20%~30% of transplanted fat will be absorbed, and its absorption rate varies from 10% to 50% according to different parts. The part that absorbs a lot is the lips, and the part that absorbs little is the eyelids.

Of the absorbed fat, 70%~80% will be absorbed within one month, 20%~30% within three months, 5%~ 10% within six months, and then only a very small amount will be absorbed, so the effect of autologous fat enrichment is very good. After the first autologous fat filling, the transplantation can be repeated 2~3 times depending on the fat absorption. After injecting enough fat, the transplanted fat cells will not be absorbed and live forever.
