Dean Jin Mingzhe, an eye plastic surgeon at Korea Laihong Hospital, pointed out that the time of swelling after double eyelid surgery is directly related to the surgical method and everyone's physical condition. Generally speaking, the catgut embedding method has less swelling and faster regression than the incision method. Generally, the swelling is not obvious 3-7 days after incision, but it may take 2-4 weeks to completely subside. If the same surgical method is used, the swelling with small trauma will be light, and the swelling time after the second operation will be longer than that after the first operation. People with good skin elasticity will reduce swelling faster than those with loose skin, and young people will reduce swelling faster than the elderly. Local cold compress within 48 hours after operation can effectively reduce bleeding and swelling; After 3 days, hot compress is beneficial to promote venous blood and lymphatic reflux and accelerate swelling regression. In addition, you can also take some drugs to reduce swelling. Be careful not to use your eyes too much to ensure a good sleep.
