Lash Slick Lift and Lengthening Mascara

Glossier Lash Slick is the "your lashes, longer" mascara: a weightless, flexible formula with tiny curved fibers that cling to each lash for a baby-extensions effect. It is built for long wear — the brand says up to 12 hours without smudging or flaking — yet comes off with nothing harsher than warm water.

What it actually does

• Lengthens with fibers, not clumps. Japanese fiber technology uses curved fibers that attach to lashes and extend them.
• Defines and separates. The tapered comb brush with tiered bristles is designed for a precise, even coat every time.
• Stays sleek and shiny. Natural shine polymers deepen the black pigment for a glossy, lifted look.
• Conditions over time. Vegan biotin is included to soften lashes with continued use, per Glossier.
• Brand study results. In Glossier's 2-week clinical study of 34 people (ages 18–69) using the Black shade: 97% saw more definition, 94% saw added length and 91% saw better separation. Self-reported; results vary.
• Formula notes. Gluten-free and cruelty-free; free of parabens, phthalates, mineral oil, sulfates SLS & SLES and more, with under 1% synthetic fragrance.

How to use

1. Comb the tiered-bristle brush through lashes from root to tip.
2. Stop at one coat for an everyday look, or add a second for more drama.
3. To remove, hold a warm, wet cloth or warm water against lashes — no aggressive rubbing needed.

Questions

Is it waterproof?

It is long-wearing — the brand rates it at up to 12 hours without flaking or smudging — but it dissolves easily with warm water, which is how you take it off gently at the end of the day.

Is this a volumising mascara?

No — it is classified as a lengthening formula. The effect is long, separated, defined lashes rather than thick, built-up volume.

Will it smudge under my eyes in hot weather?

Resisting smudges and flakes through a full day of wear is the formula's core claim — the flexible film is designed to stay put until you dissolve it with warm water.
