I only have double eyelid on my left eye. Before using Opti-fold, I used double eyelid glue during 2 years, but the line was not maintained.
After using Opti-fold, line is maintaining like a magic! I just put tape before I sleep. Next day, line is alive!! After 2 months, I got double eye lid on right eye.
The first week, line is disappear in a few hours. However, as time passes line is maintained one day. After put tapes, you don't sleep Immediately, because line is not maintain.. And You should take enough sleep after put tape.
Finally, I think Opti-fold is very good product for previous stage who double eyelids surgery. I love Opti-fold more than anyone else. Thank you, Ray :)
