Hello! Silicone chin augmentation is generally safe, but it should be done in a regular hospital, because once it is infected or in a bad position, it must be removed and redone. Long chin should pay attention to avoid menstrual period and stop using some drugs that affect blood coagulation, such as aspirin and other antipyretic and analgesic drugs, vitamin E and other drugs that affect hemostasis. Others will undergo preoperative laboratory tests to determine whether there are any surgical contraindications.
