To use this lip gloss, simply open the cup and apply it directly to your lips. It's easy to use and gives a great matte look. Make sure your lips are clean and dry before application for the best result. As for storage, keep it in a cool and dry place away from direct sunlight to maintain its quality. The shelf life is 3 years, but once opened, try to use it within a reasonable time. Also, if you have any skin sensitivities, it's a good idea to do a patch test first.
