Double eyelid infection will generally appear red and swollen, and the wound will fester. If it appears, it is best to go to the hospital for treatment in time. But generally, there will be local swelling after double eyelid surgery, and the peak of swelling is three days. After a week, the big swelling will subside, but some small swelling may last for a long time, maybe half a month or a month. It is suggested that it is best to do a good job of detumescence after operation. If it is still in the swelling stage after one month, it will be treated.
