• Curved brush mirrors the nail shape for fast, smooth, streak-free application with less effort.
• Quick-dry technology sets polish to touch in under 60 seconds and lasts up to 10 days for reliable wear.

Ingredients and how they matter

• Hibiscus Sabdariffa Flower Extract — adds plant-based antioxidants and helps maintain colour integrity while supporting nail health.
• Undaria Pinnatifidia (Wakame) Extract — wakame bioactive contributes to nail strength and resilience against everyday stress.
• Tocopherol (Vitamin E) — provides moisture and helps protect nails from dehydration during use.
• Hexanal — a patented compound that helps strengthen keratin and improve overall nail structure.
• Ethyl Acetate & Butyl Acetate — solvents that provide smooth, streak-free application and quick drying.
• Neopentyl Glycol/Phthalic Anhydride/Trimethylolpropane Copolymer — film-forming resin that locks in bold colour and extends wear.

How to use and who this is for

Apply one coat of PC21X Nail Lacquer to clean, dry nails using the curved brush for a smooth, even finish. Let dry completely. Apply a second coat for fuller coverage and intensified color. For best results, seal with a top coat and allow nails to fully dry between layers. This product is designed for anyone seeking a strong, long-lasting colour with a glossy finish, while supporting nail health through a 21-Free formula.

Storage and care tips: store in a cool, dry place away from heat sources to maintain colour integrity and formula performance over time.

Experience with this shade may vary based on nail condition and application technique. Avoid contact with eyes and keep out of reach of children.

In a busy routine, you can expect a fast-drying, durable manicure that resists fading while maintaining true colour integrity.
