To make your lip color last longer, start by exfoliating your lips to remove any dead skin or dryness. Apply a lip balm to moisturize and prime your lips. Then, line and fill in your lips with a lip liner that matches your lipstick shade. Finally, apply your lipstick, blot with a tissue, and reapply a second layer for added longevity. Additionally, avoid licking or rubbing your lips to maintain the color.
