You can also choose autologous fat injection filling, but it has fat absorption, the lines are not fine enough, and the fat supply area needs to be wrapped for recovery. To ensure ideal results, it takes 1-7 days to recover after surgery. There is no influence on diet after surgery, just try to eat less spicy food.
