Hello, autologous fat face augmentation surgery is a relatively mature plastic surgery. The fat in this operation comes from the human body's own fat cells, and its biological characteristics are far superior to any prosthetic material, so it is non-toxic and harmless to itself, and will not produce immune response and rejection. There is no rejection, it is not easy to be infected, it is safe and will not rebound. I suggest you choose a regular hospital and a doctor with many years of clinical experience, so that the effect and safety of the operation will be guaranteed.
