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 3.6 out of 5 by 521.
Rated 2 out of 5 by from Disappointed I was so excited to try this product, as I've been happy with almost everything IT! What a disappointment with "Tightline." Initially loved the way my lashes looked, but after a short time I had black flakes under my eyes and even on my upper eyelids! Now I have three tubes of this and too late to return.

Rated 5 out of 5 by from Love this product This product delivers. It works well without clumping. Sometimes I then use mascara but sometimes I just use this alone. It doesn't line like they say unless you don't mind the risk of blinding yourself by getting so close to the eye, but does a nice job anyway. I gave this as a gift to a friend who is very timid about mascara and she liked it as well. I will buy again.

Rated 5 out of 5 by from The only mascara I use! I love this mascara! I have tried to go back to cheaper products but always go back to this one. I love the skinny applicator and I like that because it's water proof it stays on till I take it off. I got my mom using it and my girls as well. Love it!

Rated 3 out of 5 by from Not so good I wanted to try the waterproof tightline after reading a review that said it didn't burn the ladies eyes like the regular TL does which is my problem. I was really hoping this would work because I think I've tried all the black primers out there but sadly I could hardly get any primer on my lashes and it dried really fast, to fast maybe it was old? So back it goes. P S But it didn't burn my eyes

Rated 4 out of 5 by from Love this applictor The applicator is THE best. I so wish this mascara had a lot more pigment. I know I can use it as a primer and layer more pigmented mascara over it, but the fine applicator is the reason I use it. Not interested in layering. Please make it more black. If you do, I will gladly give it five stars because then it would be PERFECT
