Lipofilling, or autologous fat grafting, involves transplanting fat from other areas into the area to be filled, where blood flow is re-established in the implanted area and the fat is revitalized. Generally about three months after fat grafting, the surviving fat will be more stable. After fat filling, the effect can be permanent, but with the age change, the passage of time and other circumstances, the body’s cells will gradually aging and death, the tissue is obviously loose, the filled area can be felt concave, not filler fat does not exist or disappear. As fat grafting is accompanied by the problem of survival rate, i.e. not all of the grafted fat can survive, the survival rate is low, only 30%-70% of the fat can survive under normal circumstances. If necessary, fat grafting can be repeated after 3-6 months to achieve the desired postoperative result, which can increase the fat survival rate to achieve the desired volume. The survived fat cells are still regulated by the fat cell donor area. If the donor tissue is obese or thin, the transplanted fat cells will change accordingly. In addition, after the fat filling, candidates need to pay attention to a reasonable diet, eat more fresh fruits and vegetables, and avoid strenuous activities in the transplanted area, so as not to affect the survival of the transplanted fat.
