LOVE, LOVE, LOVE THIS PRODUCT!

This product is the best I've ever had for to my lower lashes. Most mascaras are too thick for lower lashes. Sometimes I also use it on my lower lashes when I want a more natural look. This product goes on easily, separates the lashes beautifully, doesn't clump or smudge and lasts n entire day and evening.

A Lash Game-Changer in One Tube

The IT Cosmetics Tightline™ 3‑in‑1 is an instant favorite. The skinny wand gets right to the lash roots, making lashes look fuller and longer while subtly lining the eyes. It doesn’t clump or smudge, wears all day, and replaces multiple products effortlessly. Perfect for natural, defined lashes in one easy step.

Great Mascara! My favorite, hands down!

I’ve been using tightline mascara for years now, probably ever since it came out. I love it! It’s thin brush makes putting it on much easier and I’m able to get closer to my lash line and in the corner lashes. If your hand is unsteady it is a good mascara to use because of the thinner brush. It stays on day and night if desired! I use the waterproof and it stays on even when sweating, crying and sleeping. I can’t say enough about it!

Best mascara ever!

The best mascara for people who have very thin and scarce eye lashes, the mascara gets into every single lash. The wand can go close to the eyelid so it gives like a thin eyeliner look. and most importantly, your mascara looks fuller and also natural.

Hi Tovi! Thank you for taking the time to post your review on our Tightline™ 3-in-1 Black Lash Primer - Eyeliner - Lengthening Mascara. We certainly understand how disappointing IT is when a product does not provide you with the results you were looking for. To achieve the best results, we recommend starting at the root of your lashes, hold the wand horizontally, then wiggle and sweep up and through your lashes from base to tips. For a beautiful tightline eyeliner effect, fill in gaps between your lashes while pressing the wand along the roots of your entire upper lash line. For a more dramatic look, add additional coats. IT can be worn alone or under mascara. We hope this is helpful!
