Double eyelid surgery is a very successful operation in cosmetic surgery. There are several surgical methods: embedding double eyelid, incision double eyelid, suture double eyelid/seamless trichiasis double eyelid and skin grafting double eyelid. At present, the most commonly used methods are embedding double eyelids and incision. In addition, during the first two weeks in double eyelid surgery, smoking and alcohol should be banned, pregnancy and menstrual period should be avoided, and oral aspirin or aspirin-containing drugs and Chinese patent medicines with the function of promoting blood circulation should be avoided, because these drugs will aggravate double eyelid surgery's bleeding and may increase the risk of double eyelid surgery.
