The same incision width can give completely different results for different eyes. Therefore, the pre-operative design of 7mm is only the distance from the incision to the lid margin, but the actual operation also takes into account the degree of laxity of the upper eyelid, so the specific width after recovery varies from person to person, and it is not only the incision width that determines the width and shape of the double eyelid. If the upper eyelid is loose, the preoperative design will be 8~9mm, and the eyelid will look narrow, if the upper eyelid is tight, the design will be 4~5mm, and the eyelid will look wide and nice. The width of the double eyelid is decided according to each person. In the six months after surgery, people who don’t know each other won’t be able to tell that there are traces of surgery, but we can’t exclude individual people, special people with individual special jobs, such as TV hosts or candidates from the show business, who want to do a wider one. After the recovery, such double eyelids will also be wider and others can see it. Therefore, I hope that the majority of beauty seekers, if not because of the need for work, it is recommended to choose the width of the double eyelid according to their own situation and the proportion of their facial features.
