I've had smudged mascara for as long as I can remember. I've tried not using eye cream (though I need it now), powdering my lashes before using waterproof mascara, nothing worked. Every day I'd find little bits around my eyes, smudged. I got a little too inclined to check myself in a mirror no matter where I was or who was around, so I wouldn't look like a makeup train wreck.
Finally, I asked my aesthetician if she had any ideas and she said, "Blinc!" So I came home, found that Birchbox carries it, and ordered up my first tube.
It's just like everyone says--easy to apply, quick to dry, and easy to remove later, with water and very gentle rubbing/pulling. Never going back...
