What if the face is too thin? Facial fat filling is to extract a part of fat from places with more fat accumulation, such as abdomen or inner thighs, and then centrifuge the center of the circle to extract pure fat, and then inject it into the needed parts of the face. Anesthesia adopts painless sleep anesthesia, so the whole operation process will not feel pain. After the first facial fat filling operation, 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. Surgery can use local anesthesia or general anesthesia, generally without hospitalization. After 1~2 weeks, the swelling was reduced and normal work and life could be achieved.
