Using this lip gloss is super easy. First, make sure your lips are clean and dry. Then, take the applicator and gently apply the lip gloss from the center of your lips towards the corners. You can apply one or more coats depending on how intense you want the color to be. As for precautions, keep it out of reach of children. If it gets into your eyes, rinse them immediately with plenty of water. To maintain the quality of the lip gloss, store it in a cool and dry place, away from direct sunlight.
