Why We Recommend It
Kosas has created a mascara that genuinely delivers the big, fluffy lashes we all want, while using a formula that's actually good for your lashes. The Big Clean Mascara uses biodegradable plant-based sugars instead of the microplastics typically used to create long-wearing formulas.
The formula includes biotinyl tripeptide-1 to encourage thicker lashes, castor oil for nourishment and shine, and provitamin B5 to maintain elasticity. It's essentially a lash serum disguised as a mascara.
The oversized curved brush has flexible, spiralled bristles designed for maximum volume and separation without clumping. It's clinically tested, ophthalmology tested, and safe for sensitive eyes and contact lens wearers.
