IT Cosmetics Tightline Full Lash Length Black Mascara Primer


An award-winning game-changer in mascara and eyeliner technology. It is your mascara, mascara primer and eyeliner in one. If you have sparse or missing lashes, the Tightline™ brush lays down black pigment along your entire lash line, filling in spare spots, giving you a full beautiful lash line and the look of an eyeliner! This creates instant definition without taking up extra eye lid space.

  • First Ever Primer + Mascara + Tightline™ Liner All in One
  • Gets to the “root” of the eyelashes
  • Ultra black formula lengthens and thickens
  • No clumping formula
  • Protects and conditions eyelashes
  • Maximizes the results of your favorite mascara
  • Paraben-free, Fragrance-free and Sulfate-free

The skinny wand also allows the conditioning serum to infuse a blend of lash-enhancing ingredients including Peptides, Collagen, Proteins, Biotin, Nettle Extract, Green Tea, Jojoba, and Vitamins all the way down to the root of your lashes. Paraben-free, fragrance-free, phthalate-free, sulfate-free, and it is great for even the most sensitive eyes.

I love me some mascara and I’m a sucker for gimmicky products so as soon as this came out I just had to snag one for myself. Honestly, I was hoping Tightline would be somewhat similar to my beloved Rimmel Extreme Volume Comb Mascara (reviewed here) but it wasn’t. Remember my little How To: Tightline (For Beginners) and How To: Tightline (Intermediate/Advanced Level) posts? Supposedly, with this mascara you don’t even have use an eyeliner or kohl to get the same effect. I mentioned using mascara as a liner (here) and went more in depth (here) but lining and tightlining is not the same thing.


First of all, Tightline is almost the size of a deluxe-size sample mascara and costs $24 at It Cosmetics. It is a bit pricey for such a small product but then again, they do claim it’s a “Primer + Mascara + Tightline Liner” It boasts a lot of great ingredients which is always a plus, especially if you’ve got wimpy lashes like me. It’s got beautiful reflective packaging (which was a pain to photograph – note how my camera is clearly visible in one of the above photos) which I think makes it look quite luxe. No obnoxious scent either.


That wand though is ridiculously skinny! It’s too skinny to be of any practical use as a mascara (at least for me). It did not curl nor add volume or even length to my lashes but it did darken them. If you want some subtle definition for your lashes, then It Cosmetics Tightline is for you. Personally, if I’m going to bother with wearing mascara, I’d like the mascara to at least add some volume to my sad little lashes. Just like Maybelline Great Lash Lots of Lashes Mascara, you could use It Cosmetics Tightline Mascara to coax stray lashes into the positions you want them to hold. It truly does get to the root of every lash actually making it better than Maybelline Great Lash Lots of Lashes Mascara when it comes to fixing errant lashes. The mascara wand is so tiny making it super easy to maneuver!


Tightline does not play well with other mascaras… or maybe I just didn’t find the right combo yet but my lashes refused to curl when I used Tightline before using another mascara. In that aspect, it did not work for me as a primer. As a mascara, on it’s own, it’s too “natural” for my taste. Also, more often than not, I’d end up with lashes mismatched in length a la MAC In Extreme Dimension Lash Mascara. While I was experimenting with Tightline as a liner (which btw was a bust) I found the best way (in my humble opinion) of using Tightline mascara. I’m not sure if this falls into the liner, primer, or mascara category but basically, I’ll use any other mascara that sufficiently volumizes and curls my lashes. Then when my lashes are semi-dry, I’ll go in with Tightline mascara and push them upwards so they fan out beautifully almost touching my eyebrows. Honestly, you can get the same effect using a pencil, a q-tip, or even your finger but this way was just easier and I wanted to use up Tightline (rather than trashing it or just tossing it somewhere and never using again it until it expired). This would be great for someone who is just getting into makeup (mistakes are less obvious) or for someone who is more into a natural look but for me when it comes to mascara, more is more. I will not be repurchasing Tightline, unfortunately.
