Use to define: Outline your cupids bow, crossing the lines over at the centre. 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 centre of your bottom lip. Apply your lipstick and blend. Use as a base: To prevent feathering, apply the same colour 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! Create an ombre lip: Line lips in a darker shade, blending into the lips but leaving the centre bare. Line the centre with a lighter shade, then press lips together or use a lip brush to create an ombre effect.
