Why we stand behind it
This volumizing mascara gives you max volume, length, separation, and curl with the cleanest ingredients. Biodegradable, plant-based sugars replace traditionally used microplastics for longwearing, lash-extension impact. The oversized rainbow brush works with the active hair-care formula so all lashes reach their full growth potential.
This product is ophthalmology tested, safe for sensitive eyes, non-irritating, hypoallergenic, and clinically tested to wear for 12 hours.
Clinical Results:
In a consumer study with 33 women, after using The Big Clean for 2 weeks:
- 100% saw longer, thicker, lusher lashes
- 87% did not experience smudging
this product meets
The Credo Clean Standard™
Every product we offer meets our industry leading standards for safety and sustainability.

What is an undertone?
An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Usage
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. Layer if you feel it.
For more natural-looking volume, apply one coat. For a more dramatic effect, wait 30 seconds and apply another coat.
