Apply the Eyeliner:
For pencil or gel formulas, gently apply along the lash line, starting from the inner corner and working outward. For liquid or felt-tip pens, use short, controlled strokes to create your desired shape.
Allow to Dry:

For a more intense look, you can layer the eyeliner or use a setting spray to further lock in the look.
For sensitive eyes, opt for a hypoallergenic, gentle formula to avoid irritation.
Waterproof makeup remover: Since these liners are resistant to water and oil, you may need a waterproof makeup remover or micellar water to remove the eyeliner at the end of the day.
