When I was young, I had double eyelids and a slight epicanthoplasty with a partial incision, but after 2 years it started to loosen gradually, and in the summer of 2016, one side completely loosened . I'm planning to do a revision surgery with an incision because the incision has the least possibility to come loose ! If I do it this time, it won't work out and I hope we'll be together for the rest of our lives haha
