After routine double eyelid surgery, scar growth is not likely to occur with better care. The post-operative care of double eyelid surgery includes hot and cold compresses. Within 48 hours after surgery, the tissue is in the exudation period, you can use ice compress to make the tissue reduce the exudation and prevent the post-operative swelling or make the swelling reduce. 48 hours later, the exuded tissue starts to flow back and the swelling recedes, you can use hot compress to speed up the tissue flow back, reduce the swelling and promote the recovery of double eyelid. After the tissues recover, if you continue to apply hot compresses, it will stimulate the tissues and tend to develop hyperplasia, so the method of applying hot compresses is important. The conventional hot compress program is to apply 15-20 minutes for 3-4 times a day after 48 hours of surgery, but be careful not to apply too many times or for too long, as hot compresses are beneficial to tissue recovery and often do not cause scar growth.
