Using this Peripera Ink Mood Matte Stick is super easy. First, prep your lips by exfoliating gently to remove any dry skin. Then, simply apply the lipstick directly from the stick onto your lips. Start from the center and work your way out for an even application. For a more precise look, you can use a lip brush. As for precautions, keep it away from direct sunlight and high temperatures to maintain its quality. If you accidentally get it in your eyes, rinse immediately with plenty of water. To store it, keep the cap tightly closed when not in use. This will prevent it from drying out and ensure it stays in good condition for a long time.
