Kosas Hyaluronic Lip Liner Retractable Shade 100 — Built-In Brush & Sharpener, Creamy Long-Wear Definition

Kosas Hotliner is a retractable, hyaluronic-acid–infused lip liner that defines, hydrates, and subtly plumps lips while offering a built-in sharpener and brush for precise, blended application.

Designed to give crisp shape and comfortable wear, the Kosas Hotliner Hyaluronic Acid Contouring Lip Liner combines creamy pigment with skincare-forward ingredients. The retractable format removes the need for a separate pencil, and the integrated tools make touch-ups and blending simple. Formulated to stay put for up to eight hours, this liner works as a defining edge or a full-lip color base and comes in a curated range of shades to flatter many skin tones.

How does the Hotliner create a defined but natural lip look?

The Hotliner glides on with a creamy, gel-like texture that lays down even, pigmented color without tugging. Use the slim tip to draw a crisp border, then soften the line with the built-in brush for a seamless gradient or fuller lip effect.

• Precision retractable tip for clean lines and contouring.
• Built-in brush blends edges for a soft, lived-in finish.
• Creamy pigment fills lips evenly when used as a base.

Will this liner keep lips comfortable and hydrated throughout the day?

Yes—the formula includes hyaluronic acid and konjac root to attract and retain moisture, so lips feel softer during wear. The texture is designed to minimize drying while maintaining lasting color, giving a comfortable all-day feel without frequent reapplication.

• Hyaluronic acid supports surface hydration and a plumper look.
• Konjac root adds smoothing and moisture-retention benefits.
• Creamy, non-drying finish avoids flaking or cracking.

How do the built-in sharpener and brush improve application?

The integrated sharpener keeps the retractable tip precise without needing extra tools, while the brush helps diffuse any harsh edges for a polished result. Together they make on-the-go adjustments quick and reduce the need for multiple accessories.

• Sharpener preserves a fine point for detailed lining.
• Brush softens lines for blurring, ombre, or fuller-lip techniques.
• Compact design streamlines your makeup bag—no separate tools required.

How long does the color last and how versatile is it?

The Hotliner delivers long-wearing pigment designed to stay visible for up to eight hours, resisting smudging and excessive transfer. Its richness makes it versatile: use it alone for a low-maintenance wash of color, as a liner under lipstick, or to sculpt and slightly overline for added volume.

• Up to 8 hours of wear for day-to-night use.
• High pigmentation works for lining, filling, or base layering.
• Eight shades curated to complement a range of skin tones.

Who is this for? Kosas Hotliner suits anyone who wants cleaner, longer-lasting lip definition with skincare benefits built in—ideal for busy people who prefer a single multi-tasking product, makeup minimalists who want a natural-enhancing lip, and beauty lovers seeking a creamy, non-drying formula with on-the-go convenience. Cruelty-free and formulated without mineral oil, silicones, parabens, or phthalates, Hotliner is also a good pick for those who favor Kosas Clean ingredients and vegan options.
