Using this non - stick double - ended lipstick is a breeze. First, if you want to use the lip liner part, outline your lips gently to define the shape. Then, apply the lipstick part over it for a bold and beautiful color. Make sure your lips are clean and dry before application for the best result. When not in use, keep the lipstick cap on tightly to prevent it from drying out. Also, store it in a cool and dry place. If you have sensitive lips, it's a good idea to do a patch test on a small area of your lips first. Enjoy your gorgeous lips with this amazing product!
