I've tried a billion mascaras, no joke. This is the only one I have purchased more than once. And, unless the world comes out with some super mascara that makes your lashes grow instantly, the only one I will buy. Period. It isn't waterproof, but it doesn't smudge. I've cried several times while wearing this, and it does not budge. It makes your lashed look twice as long. It doesn't leave little black eye boogers in the corners of your eyes. Even my mom purchased this after trying mine. She loved her waterproof Cover Girl stuff, but after trying this, she switched. Two thumbs up. This stuff is AMAZING. It's $18 at sephora.com.
