Is eyeliner bad for your eyes?

Eyeliner can cause severe eye irritation if it gets in the eyes, according to The Huffington Post. TheHealthSite also warns against using eye makeup that contains mercury, lead and parabens as they can cause blindness.

Sleeping in eyeliner, according to The Huffington Post, poses a health risk. Eyeliner can rub off onto a pillow and from there get into the eyes, causing eye irritation. Eyeliners that don't contain harmful chemicals are not a health hazard if they don't get in the eyes.

TheHealthSite suggests using natural, chemical-free makeup products to avoid health risks. Adhering to the expiration date of makeup products also reduces health risks.
