I applied a generous amount, waited about five seconds, and then placed the false eyelashes where I wanted them before they dried, which helped them stay in place. The instructions say to wait until they're clear before applying, but that didn't provide much adhesive. This product doesn't adhere firmly like glue, but sticks to your eyelashes like an adhesive. It didn't come off even after a shower, and I was able to peel it off after a bath and adjust the placement without needing to reapply glue. This wouldn't be possible if the false eyelashes were firmly attached, so it seems like a great product! They don't itch, and I don't even feel like I'm wearing them. The false eyelashes I used this time were LASHIDOL CatElf glueless, three-section type, purchased from Amazon. I applied them after skincare and before applying foundation or eyeshadow.
