Born from Kose's 70-year dedication to Japanese beauty science, this eyeliner was developed for modern lifestyles where long days and screen time demand makeup that doesn't quit. Our labs in Tokyo focused on creating a formula that feels weightless but delivers unwavering color, selecting a unique blend of berry-derived pigments and a proprietary film-forming polymer. Every batch is produced in a GMP-certified facility under Japan's rigorous Pharmaceutical Affairs Law, ensuring pharmaceutical-grade precision. This commitment to quality has made it a top-ranked eyeliner in Japan, consistently earning the 'long-lasting' and 'easy to use' praise in user reviews.

The Kose Blend Berry Playful Liquid Eyeliner M - Vivid Long-Lasting Liner contains a carefully formulated blend of ingredients designed to deliver both aesthetic appeal and functional performance. Key components include water and butylene glycol, which serve as solvents and humectants to maintain the product's liquid consistency and provide hydration to the delicate eye area. Film-forming agents like acrylates copolymer ensure the eyeliner adheres smoothly to the skin, creating a flexible, long-lasting film that resists smudging and fading throughout the day. Pigments such as iron oxides and ultramarines deliver the vivid, intense color payoff, while dimethicone acts as a silicone-based emollient to enhance glide during application, ensuring precise lines without tugging. Preservatives like phenoxyethanol are included to maintain product stability and safety by preventing microbial growth. Additionally, botanical extracts, potentially from berries as suggested by the product name, may offer antioxidant benefits and a subtle fragrance. This formulation collectively provides users with a durable, easy-to-apply eyeliner that offers vibrant color, comfort, and longevity, making it suitable for creating defined eye looks with minimal irritation.
