Defining the waterline with eyeliner is a powerful way to make your eyes pop and create a bold, captivating look. The right waterline eyeliner can enhance your natural eye shape, add intensity, and complete any makeup style. This review covers the best waterline eyeliners on the market, focusing on formula, longevity, comfort, and ease of application to help you achieve those stunning, defined eyes.

1. What Is Waterline Eyeliner?
Waterline eyeliner is applied to the inner rim of the eyelids—either the upper or lower lash line. Unlike traditional eyeliners applied on the lash line, waterline liners require a gentle, smudge-proof, and often waterproof formula to stay put and avoid irritation.
2. Key Features to Look For
- Long-lasting and Waterproof: To prevent smudging and running throughout the day.
- Gentle and Safe: Formulated for sensitive eye areas to avoid irritation.
- Smooth Application: Soft texture that glides easily without tugging or discomfort.
- Pigmentation: Intense color payoff for bold definition.
