Gel eyeliner is known for its smooth texture and long-lasting formula, which often includes waterproof properties.
It provides intense color and stays put even in humid conditions or during sweating.
This makes it ideal when a smudge-proof or waterproof look is needed.
Kohl and kajal are softer pencils that smudge easily and are not designed to be waterproof.
Liquid eyeliner can also be waterproof but is more prone to cracking and needs careful application.
Among the options, gel eyeliner is the best choice for waterproof use.
