To use the Peripera Simplain Water Blur Lip Tint, simply apply it directly to your lips. Start from the center and spread it outwards for an even look. For a more intense color, apply multiple layers. When you're done using it, keep the cap tightly closed to prevent the tint from drying out. Avoid getting it into your eyes or mouth. If it accidentally gets on your skin, you can easily wipe it off with a makeup remover. Store it in a cool, dry place away from direct sunlight to maintain its quality.
