Hello, I am Dr. Yu from the Plastic Surgery Department of Shangrao People's Hospital and the Medical Plastic Surgery Department of Shangrao City. Autologous fat is transplanted with its own fat particles. As its own tissue, its biological characteristics are far superior to any prosthetic material, so it is non-toxic and harmless to beauty seekers themselves, and will not produce immune reactions and rejection reactions. I suggest you go to a local regular hospital to find a professional doctor for face-to-face consultation and surgery. Only regular hospitals can ensure safety and effectiveness. Wish you a happy life!
