1. Start with clean, dry brows. The formula adheres best to oil-free skin. 2. Using light, short strokes, sketch individual hairs in the direction of your natural growth. The 1.5mm tip is designed for this. 3. Fill in any sparse areas with gentle, feathery pressure. 4. For a softer look, use the built-in spoolie brush to blend. No setting gel is needed. Timeline Expectations: Week 1: You'll notice it 'doesn't budge' even during a workout or in humidity. No midday touch-ups. Week 2-3: The technique becomes second nature. You achieve your desired brow shape in under 60 seconds. Week 4+: The pencil becomes a non-negotiable part of your routine for its reliability, saving you from the stress of unpredictable makeup.

In Japan, where humidity and long workdays test even the best makeup, Kose created the Fasio line to solve a specific problem: brows that fade, smudge, or disappear by lunchtime. Developed in Kose's Tokyo labs, this pencil was engineered after analyzing thousands of customer complaints about 'greasy skin' and 'rubbing off.' The 1.5mm ultra-fine core wasn't an accident—it's the exact width Japanese makeup artists recommended for replicating natural hair strokes. Every batch is tested under Japan's strict GMP (Good Manufacturing Practice) standards, the same used for pharmaceuticals, to ensure the waterproof formula performs identically every time. It's not just a pencil; it's a precision tool born from listening to real frustrations, which is why it consistently ranks as a top-selling eyebrow product in Japanese beauty magazines.

The Kose Fasio Waterproof Fine Core Eyebrow Pencil - Long-Lasting 1.5mm Tip is formulated with a carefully selected blend of ingredients designed to deliver precise, durable, and natural-looking results. Key components include synthetic waxes such as microcrystalline wax and hydrogenated polyisobutene, which provide a smooth, creamy texture for effortless application while ensuring the pencil adheres firmly to brow hairs and skin without smudging. These waxes also contribute to the product's waterproof and long-wearing properties, resisting moisture from humidity or perspiration throughout the day. Pigments like iron oxides and titanium dioxide are incorporated to offer a range of natural shades that mimic real brow hair, allowing for customizable definition and fill. Additionally, film-forming agents such as trimethylsiloxysilicate create a flexible, breathable barrier that locks color in place, enhancing longevity without feeling heavy or stiff. Emollients like isododecane and squalane help condition the brow area, preventing dryness and ensuring a comfortable wear. This combination of ingredients works synergistically to provide users with a fine, precise tip for detailed strokes, buildable coverage for tailored intensity, and all-day resilience that maintains a polished appearance in various conditions.
