To use this 3CE lip color, simply apply it directly to your lips. Start from the center and spread it outwards for an even application. For a more intense color, you can add an extra layer. Remember to keep the lipstick away from high - temperature places to prevent it from melting. Also, avoid leaving it open for a long time to maintain its moisture and texture. If you have sensitive lips, it's a good idea to do a patch test on a small area of your lips first. When not in use, store it in a cool and dry place to ensure its quality.
