Glossier Lash Slick lengthening mascara — True Black 0.29 oz, weightless tubing, up to 12hr wear

Glossier Lash Slick is a weightless, tubing-style mascara that lengthens and lifts lashes with smudge-resistant wear and conditioning ingredients for a natural, defined finish.

Designed to imitate the look of longer, separated lashes without the heft or clumping of traditional mascaras, Lash Slick uses tiny curved fibers and a flexible film-forming formula to cling to each lash. The peptide- and biotin-enriched recipe aims to feel lightweight while supporting a sleek, glossy lash line that stays put for up to 12 hours and rinses off with warm water.

How does Lash Slick create visible length without clumps?

Lash Slick combines ultra-fine Japanese fibers with a tapered comb brush so each stroke deposits fibers and film where you need them, building length instead of volume-heavy clumps. The wand’s shape helps separate lashes and coat them from root to tip for a naturally elongated silhouette.

• 1mm and 2mm curved Japanese fibers adhere to individual lashes
• Tapered comb brush lifts and separates while applying fibers evenly
• Flexible tubing film forms around lashes to prevent flaking and clumping

Will this mascara stay smudge-resistant through my day?

The formula is built to resist smudging and flaking for long wear—Glossier reports up to 12 hours—without feeling stiff. Because it forms a thin, flexible tube around each lash, it stays put during normal daily activities and removes cleanly with warm water.

• Weightless flexible film locks fibers in place for long wear
• No visible flakes or smudges throughout the day
• Easily removes with warm water—no heavy makeup remover needed

What conditioning ingredients are included and why do they matter?

Beyond lengthening fibers, Lash Slick contains Provitamin B5, Biotinyl Tripeptide-1, and vegan biotin to support softer-feeling lashes and a conditioned appearance. These ingredients are selected to help lashes look cared-for while you wear mascara, without adding weight or sticky residue.

• Provitamin B5 helps lashes feel hydrated and smooth
• Biotinyl Tripeptide-1 and vegan biotin contribute to a more nourished-looking lash line
• Lightweight peptide base avoids stiffness and keeps movement natural

How do I apply and remove Lash Slick for best results?

For precise, clump-free results, sweep the tapered comb from the root of each lash to the tip in a gentle zigzag motion. The brush is designed to reach top and bottom lashes; add a second coat where you want extra length. To remove, warm water and a little patience dissolve the tubing film—no harsh rubbing or heavy removers required.

• Sweep wand from root to tip for separation and lift
• Apply multiple thin coats rather than one thick coat to avoid buildup
• Warm water removal: let water loosen the tubing then rinse away gently

Who is this for? Lash Slick is aimed at anyone seeking a natural, defined lash look—especially people who prefer weightless formulas, wear contacts or have sensitive eyes, and those who dislike clumpy, flaky mascaras. It’s a versatile option for everyday beauty, quick routines, and wearers who want the appearance of longer lashes without falsies or heavy layering.
