1. Start with clean, dry brows. 2. Using short, light strokes, fill in sparse areas following your natural brow shape. The drop-shaped core allows for both fine lines and soft shading. 3. For a natural look, many users apply it right after their morning skincare, before foundation, to help it set. 4. Use the built-in sharpener to maintain the precise point. Timeline Expectations: Week 1: You'll notice it doesn't smudge when you touch your brows or in humidity. Week 2-3: The routine becomes effortless—no midday checks or fixes needed. Week 4+: You rely on it for a defined, natural-looking brow shape that lasts from your morning coffee until you wash your face at night.

Born from Kose's 75-year dedication to Japanese cosmetics science, this eyebrow pencil was created to solve a modern problem: makeup that can't keep up with busy, on-the-go lifestyles. Our researchers in Tokyo developed the unique drop-shaped core after analyzing thousands of user feedback points, specifically to address the frustration of smudging and fading. Every ingredient is selected under Japan's strict Pharmaceutical Affairs Law, and the formula is manufactured in a GMP-certified facility that also produces medical-grade products. It's not just another pencil; it's engineered precision, resulting in its consistent top-ranking position in Japan's @cosme beauty awards for long-wear eyebrow products year after year.

The Kose Fasio Waterproof Eyebrow Pencil - Long-Lasting Drop-Shaped Core contains a carefully formulated blend of ingredients designed to deliver precise, long-lasting eyebrow definition. Key components include synthetic waxes such as microcrystalline wax and hydrogenated polyisobutene, which provide the pencil's smooth, creamy texture for effortless application while forming a flexible, waterproof film that resists smudging and fading throughout the day. Pigments like iron oxides and titanium dioxide offer natural-looking color payoff and opacity to fill in sparse areas and define brow shape. Silicone derivatives such as dimethicone contribute to the product's slip and blendability, ensuring even distribution without tugging on delicate brow hairs. Additionally, film-forming polymers enhance adhesion to skin and hair, locking color in place for extended wear. Antioxidants like tocopherol (vitamin E) may be included to protect the formula from oxidation and provide mild conditioning benefits. This combination of waxes, pigments, silicones, and polymers results in a user-friendly pencil that delivers waterproof, smudge-resistant brows with a natural finish, ideal for maintaining defined eyebrows in various conditions.
