My eyes had a lot of fat and no double eyelid at all, so I was advised to do the incisional method. They said if I did natural adhesion or buried sutures, it would come undone right away, so I went ahead with the incisional method. But because I had the double eyelid line set thin, after 1 year it went back exactly as it was.
For people with a lot of fat in their eyelids, do the incisional method, and considering that the line will recover, ask them to set it with a little extra room.
