Is Lash Slick waterproof?

No. Glossier describes it as water-resistant, not waterproof, and says it wears up to 12 hours without smudging or flaking.

Mainly length and definition. The fine fibers coat each lash for a natural look, so it gives little thickness compared with volumizing mascaras.

Use an oil-based cleanser or eye makeup remover. Plain water alone won't break down the water-resistant formula.

Is it good for sensitive eyes or contact lens wearers?

The light formula suits many contact lens wearers, but it contains fibers, so check the ingredient list if you have sensitive eyes.

What shades does it come in?

Glossier sells it in Black and Brown; the 12-hour wear claim was tested on Black only.

Our take on the Lash Slick

Lash Slick is Glossier's best-selling lengthening mascara, built around tiny curved fibers that coat each lash for a soft, extension-like look rather than volume. The formula is water-resistant but not waterproof, and Glossier says it wears up to 12 hours without smudging or flaking, tested in Black only. Provitamin B5 and vegan biotin condition lashes over time. It suits people who want natural definition and length, not dramatic volume; shoppers wanting thick, bold lashes will find it too subtle.

About the Lash Slick

Lash Slick is a mascara that lengthens and lifts lashes for a natural, extension-like look. The flexible formula is weightless. It contains tiny fibers that coat each lash from root to tip for definition.

The formula uses one and two millimeter-long curved Japanese fibers that cling to each lash and add length without weight. Provitamin B5 and Biotinyl Tripeptide-1 help lashes look sleek and shiny. Vegan biotin conditions lashes so they feel softer over time. Natural shine polymers enhance the black pigments for extra shine.

The tapered comb brush has tiered bristles and a precise tip. It separates top and bottom lashes at the root for even application. The formula is water-resistant, not waterproof. It stays in place for up to 12 hours without smudging or flaking, tested on Lash Slick in Black only.
