Step 1: Prepare your lips

• Gently exfoliate your lips to remove dead skin, using a gentle sugar scrub or a soft brush.
• Apply a thin layer of lip balm and blot off any excess to create a smooth canvas. 

Step 2: Outline your lips

• Sharpen the liner if it's a pencil to ensure a precise tip.
• Hold the liner at an angle and begin at the center of your cupid's bow, gliding the pencil outwards towards the corners of your mouth.
• Repeat on the bottom lip, starting in the center and working your way to the corners.
• Connect the corners to complete the outline. For a more defined or fuller look, you can slightly overline your natural lip line. 

Step 3: Fill in and blend

• For long-lasting color, you can fill in your entire lip with the lip liner, which also helps to prevent lipstick from bleeding.
• For a seamless transition, blend the liner inwards with your finger or a lip brush.
• Apply your lipstick or lip gloss on top. The matte lip liner provides a long-lasting and smudge-proof base.
