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.

Big Lash Energy

    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.

    Loucious Lashes

    This mascara gives me loucious lashes. It's vloumizing, lengthening and long lasting. It doesn't flake or smudge and lasts all day. This is my go to mascara, love to pair in with the 10 second eyeshadow.

    Awesome mascara

    This is the best mascara. I’ve tried so many over the years and none compare. Great volume and length.

    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!
