Draw the Sharpest Wing of Your Life

The ultra-fine brush gives you 'surgical precision' and 'makes a perfect cat-eye easy,' even if you have unsteady hands or are a beginner.

No More Panda Eyes, Ever

This formula 'does not budge' with sweat or oil, so you avoid the embarrassing smudges and raccoon eyes that come from daily stress and long hours.

Saves You Time Every Morning

Because it's 'so easy to apply' and dries fast, you get a flawless line in seconds, not minutes, making your routine more efficient.

Comfort You Can Forget About

Reviewers note it 'feels like nothing' on the skin—no tightness, itching, or heaviness, so you can wear it for 16+ hours without irritation.

One Stroke, Full Coverage

The intense black pigment means you don't have to go over the line multiple times, getting a bold, opaque look with a single pass.

Confidence Through Any Weather

It's 'truly waterproof,' proven in Japan's humid summers, so rain, humidity, or emotional moments won't ruin your carefully crafted look.

A Sustainable Choice That Performs

The refillable design means you're making a smart choice for your wallet and the planet without sacrificing any professional-grade performance.

1. **Waterproof Polymer Film** — Utilizes a proprietary, quick-drying polymer that forms a flexible, water-resistant film on the skin, tested to resist sweat, tears, and humidity. 2. **High-Precision Brush Tip** — Features a 0.55mm ultra-fine brush made of 32 tightly bundled synthetic hairs, designed to mimic the control of a calligraphy pen for sharp lines and wings. 3. **Intense Carbon Black Pigment** — Contains a high concentration of specially milled black pigment for a single-stroke, deeply saturated black line that doesn't appear gray or sheer. 4. **Smudge & Transfer Resistance** — The formula is specifically engineered to set and adhere to the skin without migrating to the crease or transferring onto the upper eyelid. 5. **Long-Wear Formula** — Clinically tested in Japan for up to 24-hour wear resistance under normal conditions without fading or flaking. 6. **Quick-Drying Technology** — Dries to a smudge-proof finish within 60 seconds of application, preventing accidental smearing. 7. **Flexible Film** — The polymer film is designed to be flexible, so it moves comfortably with the skin without cracking or feeling tight. 8. **Oil-Resistant Base** — Formulated to resist breakdown from natural skin oils (sebum), a primary cause of eyeliner smudging. 9. **Japanese GMP Certification** — Manufactured in a facility certified for Good Manufacturing Practices, ensuring pharmaceutical-grade hygiene and consistency. 10. **Allergy-Tested** — Dermatologist-tested and formulated to be free from parabens, mineral oil, and synthetic fragrances to minimize irritation. 11. **Refillable System** — The pen design allows for easy cartridge replacement, reducing plastic waste.

1. Shake the pen gently 2-3 times before use to ensure optimal ink flow. 2. Hold the pen like a pencil, close to the brush tip for maximum control. 3. Starting from the inner corner, draw a thin line as close to your lash line as possible, using short, steady strokes. For a wing, extend the line outward from the outer corner of your eye. 4. Allow 30-60 seconds for the formula to dry completely to a smudge-proof finish. Do not blink forcefully during this time. 5. To remove, use a dedicated oil-based eye makeup remover. Gently press and hold the remover-soaked cotton pad on the lid for 15 seconds before wiping away. Timeline Expectations: Week 1: You'll notice the intense black pigment and how the fine brush makes application easier and more precise than a typical felt tip. Week 2-3: The true waterproof and transfer-resistant performance becomes clear, lasting through long days without fading or creating panda eyes. Week 4+: The eyeliner becomes a trusted, effortless part of your routine, saving you time and worry about your makeup's staying power.

Born from Kose's 70+ years of Japanese cosmetic science, the Fasio Liquid Eyeliner was created to solve a universal frustration: eyeliners that smudge, fade, or require constant reapplication in our busy, modern lives. Our chemists in Tokyo developed this high-precision formula using a unique polymer film technology, tested in Japan's humid climate to ensure it withstands sweat, oil, and humidity without transferring. Every batch is produced in a GMP-certified facility, adhering to Japan's strict Pharmaceutical Affairs Law for cosmetic safety. It's not just a makeup product; it's a reliable tool for anyone who wants their look to stay put from morning meetings to evening events, which is why it consistently ranks as a top-selling eyeliner in its category for long-wear performance.

The Kose Fasio Liquid Eyeliner - Waterproof High-Precision Definition contains a carefully formulated blend of ingredients designed to deliver precise application, long-lasting wear, and user comfort. Key components include water and butylene glycol, which serve as solvents and humectants to maintain the product's liquid consistency and prevent drying on the skin. Film-forming agents such as acrylates copolymer and styrene/acrylates copolymer create a flexible, waterproof barrier that resists smudging, fading, and moisture, ensuring durability throughout the day. Pigments like iron oxides and carbon black provide intense, opaque color payoff for sharp definition. Emollients such as dimethicone and hydrogenated polyisobutene contribute to a smooth application and enhance skin feel by reducing drag during use. Preservatives like phenoxyethanol and ethylhexylglycerin ensure product stability and safety by preventing microbial growth. Additionally, ingredients like sodium hyaluronate may be included for their hydrating properties, helping to maintain the delicate eye area's moisture balance. This formulation collectively offers benefits of high precision, smudge-proof longevity, and comfortable wear, making it suitable for creating defined eyeliner looks that withstand various conditions.
