This method needs to cut the skin, which is slightly traumatic, but the upper eyelid structure can be adjusted through the incision, and the effect is reliable and lasting, which is suitable for single eyelid in various situations. 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.
