Under normal circumstances, the time of swelling reduction after double eyelid surgery is directly related to the surgical method. Generally speaking, it takes 7- 14 days for basic swelling reduction and 1 month for complete swelling reduction. After double eyelid incision, the basic swelling usually takes 10-20 days, and the complete swelling takes about 2-3 months. 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.
