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.

Rated 5 out of 5 by from Best Mascara For Me I use this as my mascara all the time. I love the size of the brush! I love that it never irritates my eyes as I have very sensitive eyes. Last all day.

Rated 5 out of 5 by from Love This Wand I love this wand, it’s super skinny and I can really get all my lashes. My eyes are small and it’s really tough to get to all my lashes with anything but this wand. Bigger wands just get messy. This formula is great for a natural look or as a primer/1st coat. It is buildable. I stick with the waterproof formula since my eyes tend to water whenever I wear makeup. If your wanting super thick lashes this is great for primer, then add your favorite volumizing mascara. I think the formula could be tweaked some more, if I use too much it sometimes flakes.

Rated 1 out of 5 by from Terrible Buy I bought this as advertised thinking it would work as shown. No is doesn’t. What a waste of money.

Rated 5 out of 5 by from Just love this mascara. I don't really wear a lot of make-up. I usually hate mascara, but this is my go to from now on. It doesn't flake. I find most mascaras flake into my eye at some point. This does not do that. It's so easy to put on and makes it look like I have lined my lids. Easy to use.

Rated 5 out of 5 by from Great Mascara This is the only waterproof mascara I can wear because my eyes constantly tear. It stays on all day and makes my thin, light eye lashes look beautiful.

Rated 1 out of 5 by from NoWay!!! I bought this item previously and loved it. So when I saw it again on sale I bought it again. It is horrible. It is not repeat not waterproof. It came off worse then my non waterproof mascara that I normally use. I loved it because of the eyeliner effect but I couldn't even get that right with this particular batch. No more for me they're going back.
