Gel eyeliner offers a smooth, durable, and often waterproof formulation. It delivers strong color and maintains its hold in humidity and sweat, making it suitable for smudge-proof or waterproof aesthetics.
Kohl and kajal are softer pencils that smudge readily and lack waterproof capabilities.
While liquid eyeliner can be waterproof, it is more susceptible to cracking and requires precise application.
For waterproof performance, gel eyeliner is the superior option.
