FAQs

Is the formula waterproof?

The Big Clean is not waterproof, but is clinically proven to wear for 12 hours.

How would you describe the formula texture?

It’s a weightless, creamy texture for optimal pairing with a twisted wire brush.

Is this a lengthening, volumizing mascara or both?

This multi-benefit mascara promotes length, volume, and curl to the lashes.

What is in it that allows it to be volumizing and not clumpy?

Natural body-building ingredients including botanical waxes allow this mascara to be super volumizing, and a combination of emulsifiers help make it creamy and clump-free.

How do you recommend applying the mascara?

The best way to use The Big Clean is to press the brush into the base of your lashes and wiggle it through, with the curve of the brush following the natural curve of your eye.

What makes it different from other mascaras?

This is clean mascara like you’ve never seen before. The Big Clean instantly delivers big, bold lashes without commonly used acrylates, carbon black, mineral oil, fragrance or silicones. It’s also powered by haircare actives so lashes can reach their full growth potential. It’s like lash extensions and lash serum in a bottle.

Gorgeous Lashes
Received this mascara as part of my “try the website” box and loved how full it made my eyelashes look. It stayed on really well. I traveled for 7 hours the day I tried it and it looked great the entire time. It washed off fairly easy and didn’t leave black streaks across my face like other mascaras do when removing.

Love this mascara!
I read that this has been reformulated, but I am new to Kosas so I can’t speak to that. What I can say is this wand and this formula are so easy to use and make my lashes perfectly separated and gorgeous! I have short straight lashes, but this makes them look long and lifted. Works as well as Ilia, but I like this wand better for sure. Easily washes off, no fallout, and no clumps. You can really build it, but I use just one coat and am ready to go.

I really like this formula! Have already noticed a difference in my eyelashes growing in thicker after just using this for a few weeks.

Love the mascara
Love it. Doesn’t clump and barely transfers. I have Asian eyes that are oily and mascara always ends up everywhere around my my eyes. So I’m happy that this one barely transfers.

Perfect
This has a really good balance between wet and dry…I curl my eyelashes and this goes on smooth, but not super wet, so it holds things up well. This is my third bottle and I’m pretty sold.
