Using KRYOLAN Aquacolor UV Dayglow makeup is a breeze. First, slightly moisten your makeup sponge or brush. Then, pick up the makeup and apply it smoothly on your skin. You'll notice the vibrant colors right away under normal or bright light. And when you're under UV light, it's like a whole new show! Remember, this makeup is carmine-free and gluten-free, so it's suitable for many skin types. But if you have very sensitive skin, it's a good idea to do a small patch test first. After using, wash it off with soap and water. To keep it in good condition, store it in a cool, dry place away from direct sunlight. This way, your makeup will stay fresh and ready for your next colorful adventure.
