1. Start with clean, dry lashes. For best results, use an eyelash curler first. 2. Apply the mascara from the base of your lashes to the tips with a gentle zig-zag motion. The unique brush is designed to coat every lash evenly. 3. Apply a second coat within 30 seconds for more volume before the first layer sets. 4. Let it dry completely for about 60 seconds. Do not blink during this time. The waterproof film forms as it dries. Timeline Expectations: Week 1: Notice lashes hold a curl all day without drooping. Mascara applies smoothly without clumping. Week 2-3: Lashes feel conditioned and look thicker with consistent use. The curl stays put through humidity and long workdays. Week 4+: Enjoy consistently defined, lifted-looking lashes. The formula helps protect lashes from daily environmental stress, making your routine faster and more reliable.

Born from Kose's 70-year dedication to Japanese beauty science, this mascara was created for modern life. We saw how stress, long hours, and environmental factors make lashes weak and straight. Our labs in Japan developed a unique blend of berry extracts and a patented film-forming polymer to solve this. Every batch is made in our GMP-certified facility, the same standard used for pharmaceuticals. It's not just makeup; it's a treatment designed to hold a perfect curl against humidity, tears, and long days. This formula quickly became a top-ranked mascara in Japan for its unique 'curl & keep' performance, trusted by users who need their look to last from morning until night.

Kose Blend Berry Cheer Me Curl & Keep Waterproof Mascara incorporates a carefully formulated blend of ingredients designed to deliver long-lasting curl, volume, and waterproof performance. Key components include film-forming polymers such as acrylates copolymer and polyvinyl alcohol, which create a flexible, durable film that locks lashes in place and resists smudging or flaking, even in humid conditions. Water-resistant agents like beeswax and carnauba wax provide the waterproof quality by repelling moisture while adding texture and helping the mascara adhere smoothly to lashes. Conditioning ingredients such as panthenol (provitamin B5) and berry extracts (e.g., from raspberry or blueberry) nourish and protect lashes, reducing brittleness and promoting a healthy appearance. Pigments like iron oxides and carbon black deliver intense, rich color for enhanced definition. Solvents like water and butylene glycol ensure an even application and comfortable wear. Together, these ingredients work synergistically to offer users benefits such as all-day curl retention, smudge-proof wear, volumized lashes without clumping, and gentle care that minimizes lash damage, making it suitable for daily use in various environments.
