I've purchased this, but I still have some of the product I'm currently using, so I don't think I'll be using this anytime soon. I'd like to pass it on to someone who understands. For those who have eyelash extensions or perms. Comes with a cute charm! [Product Description] A new generation of eyelash coating serum for everyone who enjoys beauty while protecting the health of their natural lashes. It provides authentic coating effects while "caring on the go," and contains keratin (for concentrated damage repair) and vitamin C (for moisture barrier). It enhances the setting and lasting power of eyelashes while also supporting the health of the eyelashes themselves.
