Makeup artist Ehlie Luna recommends using waterproof eyeliners that have a creamy texture (via Marie Claire). Avoid any liquid formulas as they can get into your eyes and cause irritation. However, it all depends on the user's needs. Celebrity makeup artist Jamie Dorman told IPSY that some waterproof eyeliner might not be suitable for people who wear contacts because they can smear on the lenses.

Luna recommends the MAC Technakohl Eyeliner, which is "ophthalmologist-tested and specifically states it's safe for the waterline and contact lens wearers." Another option to consider is kajal or kohl, a type of eyeliner especially made for the waterline. Byrdie recommends the Kulfi Underlined Kajal Clean Waterproof Long-Wear Eyeliner which comes in multiple matte and shimmer colors and has a creamy texture perfect for waterline application. Applying a black or dark shade of eyeliner to the waterline can add volume to lower lashes and enhance the shape of your eyes.
