Linyi can be used as a reference institution to do autologous fat filling to change the face shape, such as Linyi Weikang Plastic Surgery Hospital. Autologous fat filling the face is to suck out fat from fat-rich parts of the human body, such as abdomen, buttocks, thighs or upper arms, and inject it into cheeks, forehead, temples and other parts that need to be changed after special treatment, thus improving facial morphology. The advantage of autologous fat transplantation is that the graft is autologous tissue, and its physical properties are far superior to any artificial tissue substitute, allograft or heterogeneous material. Fat particle transplantation is easy to obtain and safer.
