What is it: Tightline Waterproof Full Lash Length Black Mascara Primer from IT Cosmetics is the next generation of lash innovation! This waterproof formula is an eyelash primer, mascara, and eyeliner in one--a true game-changer in mascara and eyeliner technology. It includes an ultra-skinny wand, allowing you to start coating your lashes at their actual root, so you coat black along your entire lash length. This gives you ultimate length and volume. If you have sparse or missing lashes, the brush lays down black pigment along your entire lash line, filling in spare spots and giving you a full, beautiful lash line and the look of an eyeliner.

Who is it for: Anyone who wants waterproof lashes; and anyone with sparse lashes who wants the look of a full lash line with thicker- and longer-looking lashes that reach their full potential.

Why is it different: In the single step of applying your mascara, you get a primer, mascara, and eyeliner--all in one step! This lash innovation creates instant eyeliner definition without taking up extra eyelid space. The skinny wand also allows the conditioning serum to infuse a blend of unique ingredients--including proteins, biotin, collagen, olive, jojoba, avocado, and a peptide--to help give your lashes a dose of nourishment. And it's waterproof!

How do I use it: Starting at the root of your lashes, hold the wand horizontally, then wiggle and sweep the brush up and through your lashes from the very base through to the tips. For a more dramatic look, add additional coats.

Rated 1 out of 5 by from Flaky Very disappointed with this product. Easy to apply, but within a few hours of applying it, flakes were appearing below my eyes. I stopped using it 3-4 days ago, and now I've got eyelashes falling out. Threw it the trash today. :-(

Rated 1 out of 5 by from Not a fan I love IT cosmetics in general, but this product was too flaky!! It made me think it was "old" or had been on the shelf too long. Not something I will ever use again. I threw mine away.

Rated 4 out of 5 by from loved it Simply put, I loved it. It separates each strand so they are not stuck together and, because you can begin coverage nearly at the lash line, so your lashes look longer. I did not give it a 5 because it does flake a little after you’ve been wearing it. When I do couple it with their mascara I find I have to check for smudging under your lash line after a while too. But overall, I have already recommended it to friends.

Rated 4 out of 5 by from Really Good I was really surprised by this product! Tried this before using my IT Cosmetics Superhero mascara because it says it's a primer, but you could honestly use this as a stand alone mascara on those days you want a naturally pretty eyelash as opposed to the giant lashes Superhero gives you. It goes on easy and really gets to the base of the lashes and gives you a natural eyeliner look. When I put my Superhero on top, my lashes looked awesome!
