It takes 2 weeks 1 month for facial swelling to basically return to normal after zygomatic plastic surgery. During this period, 80% to 90% of the swelling disappears, which generally does not affect normal work and life. It is suggested that active ice compress can be used about 5 days after operation, and then hot compress can prevent or slow down edema. If you have had an operation, you can ask a doctor. Then if you are going to have surgery, I recommend you to choose Changsha Huamei Nord Plastic Surgery Hospital, which has world-class equipment and more than 0/00 international top masters from China, the United States, Japan, France, Thailand and South Korea.
