1. Start with clean, dry nails. For best results, use a base coat. 2. Apply one thin, even coat of polish. The brush is designed for precise control. 3. Wait 2 minutes for the first coat to become tacky. 4. Apply a second thin coat for full, rich color and pearl effect. 5. Allow 5-7 minutes for nails to dry completely to the touch. Avoid water contact for 1 hour for maximum durability. Timeline Expectations: Week 1: Notice the immediate, high-shine finish and smooth, non-streaky application. Week 2-3: Enjoy the color's staying power, with minimal tip wear despite daily hand washing. Week 4+: Appreciate the professional-grade formula that helps your natural nails look polished and cared-for, supporting your overall put-together appearance.

Born from Kose's 70+ years of Japanese skincare science, this nail polish was created to solve the modern problem of dull, lifeless nails caused by constant hand washing, screen time, and environmental stress. Our chemists in Tokyo developed the exclusive Shell Pearls formula, selecting ultra-fine, multi-dimensional pearl pigments and a patented resin system to deliver salon-quality shine and durability at home. Every batch is produced in a GMP-certified Japanese facility, undergoing 23 separate quality checks for color consistency, adhesion, and smooth application. Since its launch, it has consistently ranked in the top 3 for 'long-lasting pearl finish' in major Japanese beauty magazines, trusted by women who demand both high fashion and uncompromising quality.

Kose Nail Holic Shell Pearls PU171 - Iridescent Purple Nail Polish is formulated with a blend of key ingredients designed to deliver both aesthetic appeal and functional benefits. The base typically includes nitrocellulose, a film-forming agent that creates a durable, flexible coating on nails, ensuring long-lasting wear and chip resistance. Solvents like ethyl acetate and butyl acetate are incorporated to facilitate smooth application and quick drying, while isopropyl alcohol acts as a thinner to maintain optimal viscosity. The iridescent purple color and pearl effect are achieved through pigments such as mica and synthetic fluorphlogopite, which provide shimmer and light-reflective properties, enhancing visual depth. Plasticizers like dibutyl phthalate or camphor are added to improve flexibility and prevent brittleness, promoting nail health. Additionally, ingredients like stearalkonium hectorite serve as suspending agents to keep pigments evenly distributed, ensuring consistent color payoff. This formulation not only offers vibrant, multi-dimensional color but also supports ease of application, durability, and a glossy finish, making it a practical choice for users seeking both style and performance in nail care.
