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 577.
Rated 4 out of 5 by from Effective I purchased this for the tight line effect which it does. I also use the superhero mascara so I do wish this gave the same voluminous effect that the superhero does. I use it as a base to the superhero and on my lower lashes for a slight eyeliner appearance.

Rated 5 out of 5 by from Nice! The more I use "It" cosmetics, the more I like them! This primer is easy to use, and does what they say it does! And I am so glad I decided to get the waterproof one! I have more success with this than I had with another "good" primer and an eyelash curler!

Rated 4 out of 5 by from Nice mascara I have been using this for over a month now and I really like it. However I do not get the eyeliner look at all. I have tried and it just doesn't do it. The reason I like it is it gives me a very natural looking eyelash. Long and nicely separated. It's a big difference from the Superhero which is always clumpy. I wish they included more product the handle is tice as long as the part that has the mascara in it.

Rated 5 out of 5 by from Best waterproof mascara for bottom lashes I ordered this mascara because of the smaller brush that works perfect for my bottom lashes that were hard for me to get using a traditional brush.This brush actually lets me get mascara on every lash without it getting on my skin around my eyes.It doesn't smudge which is the second best thing.The last thing i like is that it is waterproof! This could be used on anyone that has issues with big bulky mascara wands.The question below asking who this would be good for or give a gift to didn't have that as a choice to pick.

Rated 5 out of 5 by from I love this product! I love IT's Waterproff Tightline mascara primer duo! I'm 71 now and my lashes are not as full as they once were, but this helps me line my eyelids and find all the little lashes as well as the longer ones. My eyes look great!!! Thank you for offering this product!

Rated 2 out of 5 by from Not Worth The Cost Sorry to say that this mascara is no better than the drug store brands. I love the very small brush but the mascara does NOT go on smoothly and tends to clump my eyelashes together which is weird because the brush is so skinny. Would not spend the money again on the product.

Rated 2 out of 5 by from Works...briefly I purchased this and was excited to receive them. I DO like the way worki! They make my eyelashes defined and can easily do my bottom lashes. The problem is within 1 1/2 weeks the first one was pretty dried up and getting product onto the brush was almost impossible. I went to #2 and used that one for less then 2 weeks when THAT when dried up too and seem to have almost run out of product. I put both of them into very hot water which helped for a few days and now.. I just use the brush after using another mascara since the brush does define my lashes. For the price of these I was NOT a happy camper and will not be ordering again.
