Using this Rude Cosmetics Peach Refresh Lip Oil is super easy. Just apply it directly to your lips whenever you need some hydration. It's formulated with great stuff like hyaluronic acid, shea butter, and Vitamin E to keep your lips soft and moisturized. Before you start using it regularly, it's a good idea to do a patch test. Just put a little bit on a small area of your skin and wait to see if there's any redness or itching. If you notice either of those, don't use the lip oil anymore. There's no special maintenance needed for this lip oil. Just keep it in a cool, dry place and it'll be ready for you to use whenever your lips are feeling dry.
