Using these lipsticks is easy. Just twist up the lipstick and apply it directly to your lips. You can apply a single color or layer different shades for a unique look. When using, make sure your lips are clean and dry for the best result. Keep the lipsticks away from direct sunlight and high temperatures to maintain their quality. If you have sensitive lips, it's a good idea to do a patch test first. And after each use, make sure to put the cap back on tightly to prevent the lipstick from drying out.
