Our Review Of – And Your Chance To Win – This New Beauty Game Changer!

This giveaway is now over, congrats to Emily C!

I love multitasking. My theory is, why do a bunch of things when you can do one and get the same result? Sometimes my attempts at time saving aren’t so successful – like rollerblading with a 90 pound dog running beside (and eventually over) me. It’s best, I’ve painfully discovered, to leave the multitasking expertise to the professionals – like It Cosmetics.


The It Cosmetics Tightline Full Lash Length Black Mascara Primer ($24) is being touted as a “true game changer in mascara and eyeliner technology.” This combination of eyeliner, black mascara primer and mascara sounds too good to be true. Could one slim tube really do everything necessary for long, dark, lined lashes?


The secret to Tightline’s effectiveness is the wand, an ultra-skinny creation that lets you get to the root of the lashes and apply product where most mascara brushes only pretend to reach. According to It Cosmetics, most brushes leave a full 1/3 of the lashes – the entire root area – bare. That’s a whole lot of lash real estate that’s we’ve been neglecting.


Besides the cosmetic benefits, Tightline contains conditioning agents – Peptides, Collagen, Proteins, Biotin, Nettle Extract, Green Tea, Jojoba, and Vitamins – designed to enhance and protect lashes right at the root.

This all sounded so exciting, I couldn’t wait to get testing (and stay tuned to try your luck at winner a tube!). As instructed, I held the super-skinny Tightline wand horizontally against the base of my lashes and wiggled it, then swept it through to the ends, then repeated this several times to completely coat my lashes. I also pressed and wiggled the brush into my lash line where I had sparse spots, creating the illusion of thicker lashes – the “tightline” itself.


The result: very natural-looking lashes and a definition at my lash line that mimicked eyeliner. My lashes are already black, and I suspect fairer lashes would have more dramatic results. I wore Tightline alone the first day, and did have flaking and smudging under my eyes after a few hours.

I repeated the process the next day, but applied a separate mascara on top, and that’s when I saw more obvious results. My lashes looked long and dark, and I did not have as much of a problem with flaking or smudging. My other minor complaint, though, was the difficulty of removing Tightline. I found it harder to get off than most waterproof makeup, so I’ll probably be saving Tightline for special occasions.

  1. So glad to see you reviewed this–I’ve been curious about it! I’m good with tightlining my under-eye, but doing the upper lid squicks me out, so this looks intriguing. Great review!

    Also, I am cracking up at your rollerblading with a giant dog story–I tried to ride my bike with my St. Bernard once, and that went about as well as your experience did.

  2. As a mascara snob, I wasn’t so sure about this. I’ve been burned by mascara primers before (I’m looking at you, supposedly easy to apply fiber powder that dang near blinded me…)
    However, once I realized that the brand of IT Cosmetics, maker of one of my favorite mascaras ever Hello Lashes!, I knew I was in good hands.

    This is one of those products I didn’t know I needed. The wee little brush (it’s kind of adorable) REALLY got in there, just @turboterp said, and coated the lashes. I never even thought of tightling my upper eyes (and always did my lower with eyeliner) but this makes perfect sense. I was mostly surprised at the length; giving volume is easy, but the length I got with Tightline was really surprising.

    I highly recommend this, but completely agree with Amanda’s Cons. But look at the Pro list!!!

  3. Seems like a great product, I hear so much positive feedback on It cosmetics products, been curious try one of their products.

  4. Great Review @turboterb I LOVE IT COSMETICS! I have to confess this is one product I have not tried. However, you have lured me and now I maybe hooked!

  5. i do like it cosmetics mascara so this might have to go on the to try list! i think maggie cheung has gorgeous eyes!

  6. My grandmother had the prettiest eyes and no makeup – just a beautiful lady – but red lipstick for sure

  7. My 6th grade English teacher had the most beautiful blue eyes. I felt like I’m drowning every time I looked at her up close. Also, that was so very awkward :D

  8. Prettiest eyes ever has to be Elizabeth Taylor….what a beautiful purple/blue/gray color….unlike anything I’ve ever seen!

  9. Vanessa Caraballo

    I’d have to go with Beyonce. I adore her eyes! From full stage makeup to a makeup free Queen B, all I see is perfection :)

  10. This wand reminds me of the lower lash wand from the Maybelline The Falsies Big Eyes Volum’ Express mascara.

  11. I don’t really follow celebrities and such but I do love my eyes! They are one of my best features. :)

  12. I have tried several products from “IT Cosmetics” I have loved and use every one I’ve tried so far, including my ultimate “must have” Tightline Mascara Primer. I have long lashes but they are very light and I’ve always had issues with putting other mascara’s on all of my lashes. When I am in a rush and don’t have time for a lot of makeup, I always make sure to use a BB or CC cream, Tightline mascara primer, some blush and whatever my favorite lip product is for the day! It coats my baby fine lashes, especially the inner lashes and lower lashes. I use 2 coats and sometimes add mascara after application. I do agree with WHT’s review about the flaking issue and removing it is a challenge. It’s worth the payoff, for me though.

  13. I think Beyoncé has the prettiest eyes. They are very expressive and full of energy. I feel like her life and story thus far is interesting enough to make want to know more about her.

  14. I have always wanted to try IT Cosmetics, but haven’t had the opportunity. I love the idea of a mascara that gives the look of fuller lashes and eyeliner, especially since I suck at applying liner. Thank you for the giveaway!!!

  15. I think Anne Hathaway has nice eyes, they are so big! (I have really small, hooded eyes, so I love big, beautiful eyes) :-)

    Thanks for having this giveaway!
