Why You'll Love IT

Developed with plastic surgeons, this best-selling innovation is your peptide-infused lash primer, eyeliner and mascara, all in one game-changing formula that’s clinically shown waterproof even after 12 hours of wear!

This unique wand also allows the ultra-conditioning formula, infused with hydrolyzed collagen, proteins, biotin, jojoba, saw palmetto, chamomile, aloe, açai, amino acids and antioxidants, to nourish your lashes from root to tip for revolutionary lash-changing results!

Customer Reviews

Tightline Waterproof 3-in-1 Black Primer - Eyeliner - Mascara is rated 4.3 out of 5 by 36.
Rated 1 out of 5 by from What changed? Did IT Cosmetics change the formula of this mascara? I bought a tube a year ago, and it was perfect. I love the tiny brush and it provided nice, natural coverage without clumping. It didn't smudge or flake and nicely fanned-out my lashes. When it was time to reorder, the waterproof version was not available on any website, so I ordered the regular version. It was okay, but I have watery eyes, so it would sometimes smudge. I used another tube of the regular version, because once again, the waterproof was out of stock. This time, it clumped, flaked, and the tube dried out quickly. I finally was able to purchase the waterproof mascara again, and it is horrible. By mid-day, my face is covered in tiny mascara flakes, and to make it worse, I wear contacts so the flakes get under my lenses. The first version of the mascara was amazing, but something has changed and it is absolutely one of the worst flaking mascara I have ever used now. I wish I could find something with a similar brush that wouldn't flake.

Rated 4 out of 5 by from Definition but not very lengthening I wish I hadn't tried this waterproof version before trying non-waterproof Tightline which I prefer. I find this primer / mascara to be too dry even with one carefully applied coat and I don't like dry looking lashes. It hasn't worked too well with many other great mascaras from IT Cosmetics, Benefit, Lancôme, Armani, Dior but when I've used a clear / white somewhat flexible lash primer I've had better results. It's awesome on bottom lashes for serious definition. Alone on curled lashes it's very defining. I prefer a more flexible formula although this can keep curled lashes in place well.

Rated 4 out of 5 by from Awesome This is a great mascara, but it doesn't give you a full lash look, so pair it with the 5-in-1 and it works great!

Rated 5 out of 5 by from Love the small wand!! I love this product. I have seasonal allergies with very watering eyes. I have been looking for a waterproof mascara. This product is great. The small wand is very easy for me to use. It is hard for me to use wands with the large brush. Sometimes I make a big mess and have to clean it up. I am very happy with the Tightline Waterproof Primer-Eyeliner-Mascara.

Questions & Answers

I love this mascara, but it dries out so fast! What can I do to prevent this? I'm on my third tube.

Hello there, thank you so much for reaching out to us about this! Tightline should last about 2-3 months before IT needs to be replaced. If you experience this again we suggest reaching out to the original point of purchase for further assistance! XOXO Molly

Is it hypo-allergic? I have very sensitive eyes. Does it work for people who wear contacts?

Asked by: hyatt93
Hi there, thanks for your question! While IT is not specifically tested for this, IT is made with sensitive skin in mind and skin loving ingredients. Many IT Girls with similar concerns are able to use Tightline without issue. We do always suggest consulting your physician before trying new products! XOXO Molly

One girl commented that she sterilize wand after each use before placing back in holder. Is this a good idea to do with mascara and what would you use?

Asked by: meatloaf
Hi there, thanks so much for reaching out! This is not something we recommend as it may alter the consistency of the actual mascara. We suggest replacing you mascara every three months to ensure IT is safe to use! Hope that helps! XOXO Molly

Seems like you come out with a new mascara every 3 months or so (I've bought 3 but there have been LOTs of different ones. Yet this tiny tightliner (which I have and love) is the only one you offer in waterproof. And it's SOLD OUT! What gives?
