Under normal circumstances, it takes at least 3 months for the shape of the eyelid to return to its natural appearance, usually 6 months, and in a few cases, more than a year. As for the question of “no trace of closed eyes”: a successful full eyelid surgery, after recovery, the trace is not obvious. As time goes by, the fine line scars will become very faint and inconspicuous until they are almost invisible. This is related to two factors: 1. The special characteristics of the skin of the upper eyelid The skin of the eye is the thinnest, with the richest blood circulation and the strongest healing ability. Double eyelid surgery incision is designed along the skin texture, so it is not easy to grow scars, and deep in the double eyelid crease, more hidden. 2, the doctor’s technical level If the doctor’s operation is more delicate, the suture also adopts non-invasive technology and needle and thread, the damage to the skin tissue will be smaller, the skin tissue at all levels of precise alignment, the scar will be relatively slight. If multiple small incisions are chosen, the scars will be even less noticeable. Why do some candidates have scars after double eyelid surgery and others don’t? First of all, it is normal to have scarring during the recovery period. When there is an incision, there is trauma. During the healing period of trauma, there is a protective proliferation of capillaries, which leads to abnormal metabolism and arrangement of collagen, and excessive deposition of mucopolysaccharide-rich matrix, which causes the scar tissue to bulge out, the appearance of which is keloid hyperplasia. Secondly, the doctor’s skill or surgical environment is not up to standard. The environment of the surgery: failing to achieve aseptic operation may lead to infection and scarring. Doctor’s technique: if the technique is not up to standard there is a defect in the skin, and the forced suture causes over-tightening and misalignment, it may lead to keloid scarring. If the postoperative wound healing is poor, bleeding, hematoma, wound exposure to water or even infection, cracking, etc., there may be obvious scar formation. Finally, improper postoperative care. 1, hot compresses after the swelling period As we all know, there is nothing wrong with cold and hot compresses after double eyelid surgery. If after the swelling period, you should try to avoid hot compresses on the wound. If you continue to apply hot compresses or the temperature of the hot compresses is too high, it may produce scars. 2, did not remove the line began to wash the face make-up double eyelid in the removal of money, to keep the surgical part of the wound clean and dry, before removing the line is not to dip in the water. If you start to put on makeup or wash your face at this time, the wound will not be clean and it will be easy to get infected and produce scars. 3, postoperative diet is not taboo greasy, spicy, seafood and other foods, citrus foods, tobacco and alcohol will stimulate scarring, so in the recovery period to do a good job of taboo. Diet to increase the intake of protein vitamins into the amount, such as eating more lean meat, eggs and vegetables and fruits, etc., in order to facilitate the smooth healing of surgical wounds.
