When people talk about double eyelid surgery, they all know that there is a difference between "cutting" and "burying". In fact, all kinds of double eyelid surgery names that sound very scientific and novel are actually nothing more than one of the two. Double eyelid plasty is always divided into two types: incision and ligation. Ligation can be divided into two types: suture removal and suture removal. The latter is what we usually call "buried suture method". According to the principle of previous double eyelid surgery, people with thick eyelids, loose eyelids, blisters and special professional requirements, as well as people who have buried stitches for many times and performed double eyelid surgery, often choose incision method. For young people with thin upper eyelid skin, no slack and little fat, catgut embedding method is used.
