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.

Loved it so much I had to have another one!
I fell in love with with mascara and the formula upon purchasing it the charm store. I didn’t try it out for a while as I was working through a couple other brands and I’m so, so sad I waited as long as I did. It’s only been about a month of use and have been hooked since use two! Loved it so much that I don’t want to find myself without it so I got a backup, thank you for being my go to mascara! Volume, length, no clumping, perfect black and separates my lashes like a dream 😊❤️

Great for length / volume for and a natural look. I’ve been looking for cleaner products to replace my current favorites. The only complaint is the smudging. I live in FL - and it’s hot and by end of the day I have smudges underneath my eyes. That’s the only downside in my opinion…
