For double eyelid surgery, you must find a regular plastic surgery hospital. Double eyelid surgery is one of the surgeries with a relatively high failure rate, especially sutures and suture removal. If you are in Shanghai, you can recommend a patented seamless double eyelid project. The patented scalpel of Fuhua Hospital is very fine, but the fat is still removed very cleanly, so the cut is very thin and does not require suturing. It will be healed within 3 days. Not swollen. Its technology is extended from Korean double eyelids, but it is more effective than Korean three-point eyelids because it has multiple points. You can find out the specific details by consulting the doctors on their hospital website.
