Using this lip gloss is easy. First, make sure your lips are clean and dry. Then, take the applicator and apply the lip gloss evenly on your lips. You can add an extra layer for a more intense color. When it comes to storage, keep it in a cool and dry place, away from direct sunlight. Avoid getting water into the tube as it might affect the quality. And if you're allergic to any ingredients in the lip gloss, stop using it immediately.
