Whether or not you wear eyeliner underneath is your personal choice. People choose to wear a more dramatic look with eyeliner both above and below their eyes, while others prefer a more natural look with no eyeliner or just eyeliner on the upper lash line.

If you do choose to wear eyeliner underneath your eyes, do keep in mind a few things. First, make sure you use high-quality, waterproof eyeliner to prevent smudging throughout the day. Second, use light hands while applying eyeliner to avoid a heavy or overly dramatic look.

Finally, consider your eye shape and adjust your eyeliner application accordingly to enhance your natural look.
