When I was twenty.. I had buried sutures + eye correction, and it came undone after 6 months.. Right after that, during vacation, I had partial incision and then another 2 years.. Then I did it again with partial incision, and it came undone after 3 years
I really liked the line, and it was so natural that no one could tell I had double eyelid surgery.. Since it was buried sutures, maybe that was to be expected
The reason it kept coming undone was probably because I have really severe rhinitis, so whenever the seasons change I rub my eyes a lot I think that was a significant factor..
Now I'm planning to get it done with an incision and never rub my eyes again..
