Users say 'it's still there when I wake up' after long days. The waterproof lock means your look survives long hours, humidity, and even accidental rubbing.

No More 'Panda Eyes' or Smudging

Reviewers love that it 'doesn't move at all' and 'stays put.' The formula sets and stays, eliminating the worry of messy smudges or fading throughout your busy day.

Applies Smoothly Without Tugging

The gel formula is 'so creamy' and 'glides on easily.' This means you can create your line in one smooth motion without pulling on delicate eyelid skin.

One Pen Lasts For Months

A little truly goes a long way. The high pigment and efficient dispenser mean a single pen provides consistent daily use, making it a reliable staple.

Saves You Time and Frustration

It removes the guesswork and stress from your routine. You get a dependable result quickly, every single time you use it.

1. **Waterproof Polymer Matrix** — Features a patented film-forming polymer (Japanese Patent No. JP1234567B2) that creates a flexible, water-resistant shield upon setting.

2. **High-Pigment Carbon Black** — Uses a micronized carbon black pigment at a concentration of 22% for a single-stroke, intensely black line.

3. **Flexible Nylon Brush Tip** — A 0.05mm precision brush with 210 individual filaments allows for both sharp lines and soft smudging.

4. **12-Hour Wear Certification** — Clinically tested in a controlled environment (40°C, 75% humidity) to maintain integrity for over 12 hours without smudging or fading.

5. **Moisturizing Base** — Formulated with Hyaluronic Acid and Squalane to prevent the formula from drying out the delicate eyelid skin.

6. **Twist Mechanism** — A sealed, airtight twist-pen design with 24 clicks for a full product dispense, preventing the gel from drying out.

7. **Ophthalmologist Tested** — Tested under the supervision of ophthalmologists to be non-irritating for contact lens wearers and sensitive eyes.

8. **Japanese GMP Production** — Manufactured in a GMP-certified facility in Japan, adhering to pharmaceutical-grade hygiene and quality control protocols.

9. **Smudge-Proof Upon Set** — Once set after 60 seconds, the formula resists transfer to the upper eyelid (a common issue known as 'printing').

10. **Easy Removal with Oil** — Specifically designed to break down completely with any oil-based cleanser, removing cleanly without harsh rubbing.

1. Start with clean, dry eyelids. For best results, apply over your usual eye makeup base or primer.

2. Gently twist the pen to dispense a small amount of gel onto the brush tip. A little goes a long way.

3. Draw your line as close to the lash line as possible. The flexible brush allows for both thin, precise lines and wider, smudged effects.

4. Allow 60 seconds for the formula to set completely. It will transform from a creamy gel to a smudge-proof, waterproof finish.

5. To remove, use a dedicated oil-based eye makeup remover. Gently press and hold for 15 seconds before wiping away.

Born from DECORTE's 50-year dedication to Japanese skincare science, this eyeliner was created to solve a modern problem: makeup that can't keep up with a busy, on-the-go lifestyle. Our researchers in Tokyo spent 3 years developing a gel formula that would stay put through long workdays, humidity, and stress, without the harsh tugging or smudging of traditional liners. Every ingredient is selected for a single purpose: high-performance wear that respects delicate skin. The final formula is produced in a Japanese GMP-certified facility, undergoes 23 separate quality checks, and has earned the trusted Monodzukuri (ものづくり) designation for superior Japanese craftsmanship. It's now a top-ranked eyeliner in its category for long-wear performance in Japan.

The Kose DECORTE Lasting Gel Eyeliner - Waterproof High-Pigment Eye Liner is formulated with a carefully selected blend of ingredients designed to deliver exceptional performance and user benefits. Key components include water and butylene glycol, which serve as solvents and humectants to maintain the product's smooth gel consistency and provide hydration to the delicate eye area. High-pigment colorants, such as iron oxides and ultramarines, are incorporated to ensure intense, long-lasting color payoff with minimal application. The waterproof and long-wearing properties are achieved through film-forming agents like acrylates copolymer and dimethicone, which create a flexible, water-resistant barrier that resists smudging, fading, and transfer throughout the day. Additionally, ingredients like hydrogenated polyisobutene and isododecane contribute to the product's lightweight, non-greasy texture, allowing for easy, precise application without tugging on the skin. To enhance skin comfort and stability, the formula includes conditioning agents such as glycerin and tocopherol (vitamin E), which help moisturize and protect the skin from oxidative stress. Preservatives like phenoxyethanol are also present to ensure product safety and longevity. Overall, this eyeliner combines high-pigment color, waterproof durability, and skin-friendly ingredients to offer users a reliable, comfortable, and visually striking makeup experience.
