Review Highlights

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.

100% Saw Longer, Thicker, Lusher Lashes

Get max volume and separation with the cleanest ingredients. Biodegradable plant-based sugars replace traditionally used microplastics for a longwearing formula + big, fluffy, lash-extension impact.

Big Lash Energy

Natural body-building ingredients and pure, intense pigments deliver a big lash vibe. The oversized curved brush (like a rainbow) has flexible-yet-firm spiraled bristles that volumize, lengthen, separate, and curl lashes all the way up. 

Powerful Hair Care Serum For Clinically Proven Results

The active formula nourishes and protects to support stronger, healthier lashes over time. Every swipe helps lash hairs reach their full growth potential.
