Setup & Application: The application process is straightforward, designed for at-home use. Proper nail preparation (moisturizing cuticles, applying a base coat) and finishing with a top coat are crucial steps for achieving the best results. The flat, wide brush facilitates a smooth and even setup of the color. Compatibility: This nail color is designed to integrate seamlessly with CHANEL's broader nail care line, including L'HUILE CAMÉLIA (cuticle oil), LA BASE CAMÉLIA (base coat), and LE GEL COAT (top coat), which are recommended for optimal performance and a complete manicure routine. While it can be used independently, combining it with these complementary products enhances its protective, smoothing, and lacquered finish properties. Care: To ensure the safety and integrity of the product, always keep it away from sources of heat and open flames. Store the bottle upright in a cool, dry place to prevent premature drying or alteration of the formula.
