Key Ingredients(3)
Tocopherol
Vitamin E that acts as an antioxidant to protect nails and maintain the polish's integrity during wear.
Diatomaceous Earth
A natural mineral powder that provides texture and helps the polish adhere evenly to nails for a smooth, long-lasting finish.
How to Use
1. Start with clean, prepped nails for proper adhesion. 2. Shake bottle well to mix pigments evenly and avoid streaks. 3. Start by painting the edge of your nail with color, then sweep a thin layer across the full nail. Repeat step for a second coat. Let dry for 1-2 min between coats. 4. Finish with Nature Strong Vegan Top Coat: paint the edge first, then sweep a thin layer across the full nail and allow to dry. Pro tip: While a base coat isn't needed, you can apply Nature Strong Vegan Base Coat first to set the foundation for color. Apply the same way: edge first, then a thin layer across the nail. Let dry 1-2 min before color.
