Take Shanghai as an example. Generally, the cost of double eyelids is about 5 k-1w. The price of double eyelids in second-and third-tier cities is slightly lower than this, which may be around 3000-4000. If there is a need to lift the upper eyelid and open the corner of the eye, the cost may be higher.
Double eyelid surgery is very mature and has a high success rate. However, any operation is risky, and the effect of the operation is also related to the doctor's operation skills and the postoperative care of the beauty seeker.
Choose a professional and regular hospital for surgery, whether public or private, regular hospitals can do it. Collect more doctors' cases online, or consult and compare face to face, and choose doctors who are professional, experienced and consistent in aesthetic style, so that the expected effect will be easier to achieve.
