Review: IT Cosmetics Tightline Full Lash Length Black Mascara Primer

There is nothing I love more than dark, dramatic lashes. I’ve discovered that tightlining the upper waterline is a great trick for making your eyelashes look fuller and darker. But tightlining can be difficult and irritate the eyes, in which case usually destroys the work you’ve put in because they start watering. Luckily, IT Cosmetics has a solution!

Tightline Full Lash Review

The Tightline Full Lash Length Black Mascara Primer looks sort of like mascara, with a really thin wand and extremely short bristles. You’re able to get up really close to your lash line and darken up the spaces between individual lashes.  Some of the beneficial ingredients include Jojoba Seed Extract, Chamomile Extract, Apricot and Avocado Extract, as well as a peptide infused lash enhancing serum.

IT Cosmetics Tightline Wand

You can use this product as a mascara primer in that the short comb bristles work to separate your lashes. However, I’ve found the best way to use this product to start at the base and wiggle only about half way up your lashes… otherwise keep it to just one coat.  Since the formula might not be compatible with whatever mascara you’re using, this is the best way to avoid clumping.

This mascara primer is great for sensitive or watery eyes like mine. Although I love the look of tightlining, applying product to my upper waterline makes my eye twitch and tingle, so this is a fantastic alternative. It’s also great as lower lash mascara, or all over mascara when you just want a little definition without too much drama. The formula is long-wearing and very black.

You can find IT Cosmetics Tightline Full Lash Length Black Primer on, $24.

Have you tried tightlining yet?

    Interesting. I think tightlining or lining the upper waterline is a must, for me at least. I bought the Too Faced weird device for tightlining and eye lining but I don’t love it. IT products are really good so this is probably worth trying. But I will check to see if any of my existing mascara wands look like that one first.

    I seem to have very little luck tightlining. I bought this primer and loved the little brush. I would sit at my desk on boring conference calls with a compact mirror, using it to get evey little lash, ones I didn’t even know were there. I hadn’t used it in awhile and when i opened it recently it looked a little dry/gummy, bummer. I bought it late summer/early fall, maybe. I guess that is mascara lifespan. Usually once I abandon a mascara I don’t go back, heh! I would totally rebuy this.
