To use this Diamond FX face and body paint, first clean the area where you want to paint. You can use a brush or sponge to apply the paint. For line work, use a thin brush. When blending, start with small amounts of paint and gradually add more. If you're layering, let each layer dry before adding the next one. After use, clean your brushes and sponges thoroughly. Keep the paint in a cool, dry place to maintain its quality. Avoid getting the paint in your eyes or mouth. If you have sensitive skin, do a patch test first.
