Orientals' faces are relatively flat, unlike westerners' faces, which look more emotional. Therefore, the plastic surgery industry has introduced aristocratic surgery, which is to make your flat face look curved. There are several surgical methods for nobles: 1. Autologous fat transplantation, 2. Add collateral. Most people do aristocratic surgery in these two ways. South Korea's VIP plastic surgery recommends autologous fat transplantation. This kind of operation has basically no side effects, because you use your own body fat and you can do prp stem cell fat transplantation at the same time. This method not only increases the survival rate of your fat cells, but also improves your skin.
