Born from Kose's 70+ year obsession with Japanese beauty science, this polish was created for the modern woman whose hands are always on display. Our labs noticed that stress and daily wear were leaving nails looking dull and weak, so we developed a formula that works with your body's natural renewal cycle. We selected a unique iridescent pearl pigment, YE570, for its ability to reflect light and create a healthy-looking glow from every angle. Every batch is produced in our GMP-certified Japanese facility, ensuring pharmaceutical-grade purity and consistency. This commitment has made it a top-ranked polish in its category, trusted by women who want their nails to look effortlessly cared for, even with a busy lifestyle.

Kose Nail Holic Shell Pearls YE570 - Iridescent Yellow Polish is formulated with a blend of ingredients designed to deliver vibrant color, durability, and aesthetic appeal. Key components include nitrocellulose, which acts as a film-forming agent to create a smooth, hard-wearing finish that adheres well to the nail surface. Tosylamide/formaldehyde resin is included as a plasticizer to enhance flexibility and chip resistance, ensuring the polish remains intact during daily activities. Butyl acetate and ethyl acetate serve as solvents that facilitate even application and quick drying, while isopropyl alcohol helps in achieving a consistent texture. The iridescent yellow hue is achieved through pigments such as iron oxides and mica, which provide shimmer and depth, reflecting light to create a pearl-like effect. Additionally, stearalkonium hectorite acts as a suspending agent to prevent pigment settling, maintaining color uniformity. Camphor is often added to impart a glossy shine and improve spreadability. These ingredients collectively offer benefits like long-lasting wear, easy application, and a luminous finish that enhances nail aesthetics with minimal chipping or fading.
