I was shocked by your question: "Does double eyelid glue stick the upper and lower eyelids together?"

Embarrassed first.

I usually use double eyelid stickers to cut out the right shape, and it will not be unnatural after matching false eyelashes. Double eyelid glue is to draw an outline where you plan to fold your eyelids, and then close your eyes and air dry. When it is almost completely dry, hold it with that small support. Instead of gluing the eyelids together. Double eyelid glue only plays a role in shaping the outline.
