Use to define: Outline your cupids bow, crossing the lines over at the center. Then outline & fill the rest of your lips before applying lipstick
Use to contour: Line lips with a shade two darker than your lipstick. Then draw three lines down the center of your bottom lip. Apply your lipstick and blend
Use as a base: To prevent feathering, apply the same color liner as your lipstick, or create your own custom shade by using a different base
Use on its own: Line & fill your lips for a bold, matte look. No lipstick needed!
