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 4 out of 5 by from Best mascara But!!! I have ordered this product many times and I like it , but really feel the cost to product ratio is not there . Very small amount doesn’t last long and something has changed with it not getting the same results .

Rated 5 out of 5 by from Versatile Mascara Not only do I recommend for lower lashes but I also use ad a primer for both upper and lower. Never flakes off. I can get close to lash line when I don't want to use eyeliner. I have Tightline on auto delivery and couldn't be happier.

Rated 4 out of 5 by from Great Mascara for Little Lashes Bought this because of the tiny wand. Works great on my little lashes. Get great length and color with this formula. Only issues -- packaging is deceiving - the wand section is longer than the product section -- should be reversed. In addition, really thought I would get the tightline effect so that I would not need liner -- that is not the case for me. Makes for a great daytime look, but still need liner for evening. That being said, I think it's a great product and I highly recommend it.

Rated 2 out of 5 by from Flakes Bad I have used this for years, will never buy again. They must have changed the formula because it flakes terrible now.

Rated 3 out of 5 by from Nice mascara I like the thin brush and the mascara. My only complaint is that I get clumps. I use another product to seal the mascara. You don’t get much mascara for the price.

Rated 4 out of 5 by from Pleased Read reviews after I ordered and thought I made a mistake. My eyes water a lot, I wear contacts 24/7 and usually find 1 out of 10 mascaras primers I like that meet my needs. Mainly to not look like I haven’t slept. 1st day only primer. I have light colored short lashes. By this not being white, it really was all I needed. If there are any fibers in it, couldn’t tell. No irritation. It stayed put. Next day I used with mascara over. Perfect. Enough for just one coat of mascara & not have a fat clump of lashes. No under eye smear or removal when eyes teared outside and it did not flake off.

Rated 5 out of 5 by from Best Mascara Ever I have purchased many different brands of top-of-the-line mascaras but nothing comes close to Tightline. The formula makes my lashes look soft and youthful, and the applicator is the best one I have ever used. It allows for consistent application on each lash with no clumping, and it is easy to apply close to the root. I will use no other mascara but IT Tightline! Thank you!
