Autologous fat can be used for breast enhancement. The main way is to extract active parts from other parts of the body and then fill them on the forehead by injection. Because it is taken from your own body, there is no rejection and adverse reaction, which is extremely safe and has no sequelae. It feels real and can be absorbed, so there are no side effects. The price is around 3000-650 because different medical institutions and doctors have different surgical materials.
