Forehead surgery uses autologous fat instead of artificial prosthesis materials, with almost no side effects. Autologous fat filling has no incision, so don't worry about scars. Autologous fat filling can divide excess fat into other needed parts, and at the same time reduce the parts with excessive fat, which has the effect of killing two birds with one stone. Because it is its own adipose tissue, the surgical effect is particularly natural. The fat that survived after autologous fat filling surgery will live permanently at the transplantation site, and the operation effect is good and lasting. Because the autologous fat-rich forehead uses a "blunt needle"-shaped instrument, the needle insertion point is selected in a hidden position, and there is no scar after the autologous fat-rich forehead surgery.
