Autologous fat transplantation is the process of taking excess subcutaneous fat cells from certain fat-rich areas of the body, then processing them into pure fat particles and then transplanting them to the areas that need fat filling by injection. After transplantation, a new blood supply system will be established and the fat will be permanent. The advantage of autologous fat filler for temples is that autologous fat is less traumatic, the injection port is small and concealed, there will be no incision marks, it does not affect the appearance, and the recovery period is shorter. In addition, since the fat used is our own fat, it is easy to take the material, abundant sources, and there will be no rejection and adverse reactions, and it is a permanent filler after it becomes viable. Fat transplantation can also significantly improve the texture of facial skin. However, there is a problem with the survival rate of fat transplantation, i.e., not all of the transplanted fat will survive. If necessary, fat transplantation can be done again in the same area after 3-6 months to achieve the desired postoperative effect. In addition, after fat grafting, it is necessary to pay attention to a reasonable diet and avoid strenuous activities in the grafted area to avoid affecting the survival of the grafted fat.
