Autologous fat filler can theoretically maintain permanent results if it survives. Autologous fat filler is a medical technique that uses suction or excision to collect the fat cells from the aesthetician’s own body and fill them into other parts of the body. The fat areas taken are usually the inner thighs and lower abdomen, and the fat tissue is purified and injected into the desired areas. The common areas that are more suitable for autologous fat fillers are temples, tear troughs, forehead, cheeks, etc. Autologous fat can also be applied to fill other depressed areas of the body. Autologous fat transplantation is essentially a technique of free transplantation of autologous tissue similar to skin implants. The advantages of autologous fat filler are safety and no rejection reaction. However, the disadvantage of autologous fat filler is that the survival rate can be affected by various factors, and the normal survival rate is generally around 50%. Therefore, after transplanting fat, it may take 2-3 times if you want to achieve the desired effect. In addition, after autologous fat transplantation, patients need to pay attention to a reasonable diet and avoid massage and pressure on the transplanted area to avoid affecting the survival of transplanted fat.
