Ingredients and how they help you

• Butyl Acetate and Ethyl Acetate are solvents that allow the coating to spread evenly and form a smooth film on the nail.
• Alcohol Denat. assists in quick drying to reduce waiting time after application.
• Nitrocellulose creates a flexible yet strong film that helps resist cracking as nails flex during daily activity.
• Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer provides adhesion and durability, helping the product stay on nails longer.
• Triphenyl Phosphate acts as a plasticizer, improving the film’s flexibility so it won’t chip easily.
• Diamond Powder adds a subtle premium texture and helps reflect light for a polished shine.
• D&C Violet No. 2 provides a color-safe tint within the film for a clean look when used alone.

Usage guidance and who this is for
