Treat the operation with peace of mind, don't expect too much from the postoperative beauty, and check the general situation of the whole body before operation, check the mental state, heart, liver, kidney and other major organs. In terms of local examination, we should ensure adequate rest and sleep a few days before the operation, quit smoking and drink less in the first two or three weeks, stop using drugs containing aspirin and vitamin E, drink less tea and coffee, and do not eat processed dairy products or other snacks and foods. You can consult relevant doctors before operation to reduce postoperative pain. You don't have to worry about that. Just follow the doctor's instructions and you'll be fine. You can refer to them and learn from the Korean Plastic Surgery Network.
