Hmm! Yes! This project! It is very popular at present. Autologous fat filling is permanent. However, one drawback is that the fat you extracted is transplanted to the part you want to fill, and the survival rate is not high, so you can only rely on luck. It is possible that after filling it out, I can't see that it needs to be done two or three times. Personally think! Hyaluronic acid! You don't want hyaluronic acid to be absorbed quickly, so put on a mask.
