How many days after double eyelid surgery is the swelling the worst?
Generally, double eyelid surgery refers to blepharoplasty. Blepharoplasty is a surgical procedure that creates adhesion between the upper eyelid skin and the tarsal plate or the tendon membrane of the levator palpebrae superioris muscle, forming a double eyelid when opening the eyes. The general reference price for blepharoplasty ranges from 2,000 to 5,000 yuan per session. Noticeable improvement is usually observed within 1-2 weeks after surgery, although symptoms such as hematoma and inflammation may occur. There is no standard saying regarding "which day after blepharoplasty the swelling is the worst." Typically, swelling becomes more apparent between the third to fifth day after surgery, though the severity may vary from person to person. The detailed explanation is as follows:

During the blepharoplasty procedure, the eye tissue sustains trauma, which stimulates the body's self-repair mechanisms and triggers an inflammatory response. Due to surgical injury and local blood vessel rupture and bleeding, a certain degree of swelling occurs after surgery, although the swelling has not yet peaked. As time progresses, on the first day after surgery, the inflammatory response gradually intensifies, vascular permeability increases, and a large amount of fluid exudes into the tissue spaces, further exacerbating the swelling. By the second to third day after surgery, the inflammatory response becomes even stronger, with the maximum amount of fluid exudation and more noticeable interstitial edema. Therefore, this phase represents the peak period of swelling, during which patients may feel significant eye swelling, tightness of the eyelids, and slight difficulty when opening their eyes.
Starting from the fourth day after surgery, the body's repair mechanisms gradually predominate, the inflammation begins to subside, and excess fluid is absorbed by the body. The swelling will gradually decrease, and the appearance of the eyes will slowly return to normal. Additionally, different surgical techniques, such as sutured double eyelid surgery or full-incision double eyelid surgery, as well as individual differences in physical condition, may cause the timing of peak swelling to occur slightly earlier or later.
During the recovery period, it is important to avoid consuming spicy or irritating foods and不良生活习惯 such as staying up late, to prevent interference with swelling reduction and surgical outcomes.
