I think it is very likely that it will change back, because I originally had single eyelids, but now I have double eyelids. You can’t tell it without closing your eyes and looking carefully. The specific method is very simple, that is, often use the tip of your fingernail to lightly trace the fold line where you want to change your eyelids; or some people can directly insist on using double eyelid stickers to change the eyelids from single to double. I believe that it can be changed as long as you persist for a while.

The cost of this method is very low, you might as well give it a try:)
