Review Highlights

Perfect!!

I absolutely love this mascara. It made my non existent lashes reappear and the bottom baby lashes pop!!! It lasted all day without any smudges. Dare I say I found my Holy Grail of Mascara

Best clean mascara you can buy!

My new favorite mascara! I’ve noticed that my eyelashes are longer (I wasn’t sure that was possible!), thicker, and super fluffy! The formula is clean so it’s gentle on my eyes (even with contacts), doesn’t clump, and lasts all day long. Not to mention, it’s formulated to help with eyelash growth. It has everything you need and more in a mascara.

My Lashes Have Never Looked Better

The Big Clean is my new favorite go to mascara. It has everything I’m looking for in an everyday staple. Environmentally conscientious. Long wearing. Lash thickening. I would ten thousand percent recommend this product to any and every one and I will continue to purchase this mascara in the future as well.

How to Use

Press the brush into the base of your lashes and wiggle it upward, with the curve of the brush following the natural curve of your eye.
For more natural-looking volume, apply one coat. For a more dramatic effect, wait 30 seconds and apply another coat.
Pairs well with 10-Second Eyeshadow for a quick, easy, full eye look.

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.

LOVE!
I love this product so much, I just WISH it was waterproof. If they made the same exact mascara that was waterproof- this product would be top-notch. It does last all day, which is wild, but I do see smudging and residue that occurs under my lower eyelashes as the day gets longer. I also don’t put mascara on my lower lashes. Please make this waterproof so it doesn’t do that!

Thick and clumpy.
Did I get a bad one? I don’t know. It’s thick and chunky like when you own a mascara for about 2 months. I do like the wand though.

My eyes were happy, now a bit less so
Originally loved, 5 stars and my sensitive eyes were so happy! Then the formula seems to have gotten an update to be longer wear? Now it irritates my eyes and can only wear for a short time, bummer!
