What is it: Tightline Waterproof Full Lash Length Black Mascara Primer is the next generation of lash innovation! This budge-proof, 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, longer 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-infused, lash-enhancing serum--to give your lashes a dose of nourishment. And it's waterproof even after 12 hours of wear!

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.

IT Cosmetics TIGHTLINE Waterproof Black Mascara Primer Duo is rated 3.7 out of 5 by 591.
Rated 3 out of 5 by from I used to LOVE this. The old formulation was indeed waterproof and smudgeproof. The new ones, however, seem to smudge easily. I tear up when I yawn and there it goes. I come home from work and the smudges are all there. Did the formulation change? If so, please go back to the formulation you had before. It worked a lot better.

Rated 1 out of 5 by from Not pleased This product might work for someone who has long eyelashes, but I'm almost 63, and my lashes aren't very long and all it did was basically make a mess. I was looking forward to the tightline experience. I'm an IT girl, so I'll keep watching for a better, defining mascara that works for short eyelashes. Rated it poor for me, not others.

Rated 4 out of 5 by from Great I have been on auto ship for quite awhile with the only complaint (and it’s not really a complaint) is I would like the formula to be a little thicker

Rated 5 out of 5 by from Love It! I love this mascara, it is truly waterproof and elongates my lashes. One of the best I've tried and the price can't be beat!

Rated 4 out of 5 by from Best lower lash mascara I love this waterproof mascara, especially for lower lashes, because it doesn't smear into under eye concealer. The small brush gets into inner eye corners. I also use this to prime, my upper lashes, before applying other mascaras.

Rated 5 out of 5 by from Designed for accuracy I love this product because I am able to apply mascara specifically to my lashes. It is because of the very tiny applicator. I am very happy with this.

Rated 3 out of 5 by from Love it but can't remove it I'm very pleased with the way Tightline looks on my eyes. However I am thinking of returning it because it is so difficult to remove. Tried 3 removers that state they are formulated to remove waterproof eye make-up. They don't! If I can't find a remover that easily takes off the Tightline I will be returning it.
