This Colorkey Skinny Lasting Liquid Eyeliner is a high-precision, water-based formula designed for sharp lines and all-day wear. The ingredient list reveals a focus on film-forming polymers for longevity and nano-pigments for intense color payoff.

Texture: Fluid, Precise & Quick-Drying

• Water-Based Fluidity: With Water and Butylene Glycol as the primary solvents, the formula is lightweight and flows effortlessly through the fine-tip brush, allowing for hair-thin lines without skipping or tugging.
• Smooth Glide: Laureth-20 (in N01) and Laureth-9 (in N02) act as surfactants and emulsifiers, ensuring the pigment suspension remains stable and glides smoothly across the eyelid without feeling sticky or dragging.
• Rapid Set: The inclusion of Ethanol helps the formula dry down quickly upon contact with the skin, minimizing the risk of smudging during the application process.

Function: Smudge-Proof Lock & High-Pigment Payoff

• Flexible Film-Forming: The core of this eyeliner is the Styrene/Acrylates Copolymer and Acrylates Copolymer complex. These create a durable, flexible, and water-resistant film that locks the pigment in place, resisting sweat, oil, and blinking throughout the day.
• Intense Color: CI 77266 (Nano) (Carbon Black) provides an ultra-deep, jet-black payoff in a single stroke. The nano-sized particles ensure the color is dense and uniform, avoiding any greyish or patchy appearance.
• Stable Suspension: Xanthan Gum and Cellulose Gum (in N02) act as thickeners and stabilizers, preventing the heavy pigments from settling at the bottom of the tube, ensuring consistent color from the first to the last drop.

Targeted Benefits: Gentle Wear & Hydration

• Skin-Friendly Preservatives: Instead of harsh traditional preservatives, it uses 1,2-Hexanediol, Caprylyl Glycol, and Caprylhydroxamic Acid. This system is gentler on the delicate eye area and less likely to cause stinging or irritation.
• Hydration & Comfort: Propanediol and Glycerin (in N02) provide a humectant effect, preventing the eyeliner from feeling overly tight or drying on the skin as it sets.
• Conditioning Touch: Polyglutamic Acid (in N02) is a powerful humectant that can hold more moisture than hyaluronic acid, adding a subtle conditioning benefit to the eyelid skin.

Finish: Intense Matte & Sharp Definition

• Deep Matte: Once dry, the Styrene/Acrylates Copolymer film dries down to a true matte finish with zero shine or glitter, delivering a bold, graphic look.
• Crisp Edges: The combination of the fine-tip applicator and the quick-drying formula ensures razor-sharp edges that don't bleed or feather into the crease.
• Flake-Free: The flexible polymer network prevents the eyeliner from cracking or flaking off as the eyelid moves, maintaining a clean, flawless line all day.
