To use this eye shadow, start by applying a base color all over your eyelid. Then, use a darker shade in the crease for depth. For a pop of color, add a shimmer or flash shade on the lid. Make sure your eyelids are clean and dry before application. Avoid getting the product in your eyes. To keep it in good condition, store it in a cool, dry place. And don't forget to close the lid tightly after each use.
