In a sense, autologous fat filling is permanent. However, because the survival rate of homemade fat is only about 40%, once the homemade fat does not survive, it means that it needs to be filled with homemade fat for the second time until the fat completely survives in the part to be filled, so as to achieve the permanent effect of homemade fat filling. The durability of autologous fat filling is closely related to the doctor's skill. If the autologous fat cells are in place at one time during autologous fat extraction, the extracted fat cells are complete and round, and the cells are exposed to the air for a long time after being taken out, the viability of autologous fat cells is high. In the filling process, autologous fat is injected into the parts to be filled in layers in turn. Then the survival rate of autologous fat filling is between 50% and 90%, and the survival rate of fat cells extracted by skilled doctors can be as high as 85%. I hope my suggestion is helpful to you.
