To use this nail polish, first make sure your nails are clean and dry. Apply a base coat if you like, then paint on two thin coats of the Cosmic Moon nail polish, waiting for each coat to dry. You can finish with a top - coat for extra shine. Keep the polish away from heat and direct sunlight to maintain its quality. When not in use, tightly close the bottle to prevent it from drying out. Avoid getting the polish on your skin, and if you do, use nail polish remover to clean it up.
