In another example of why it’s not a good idea to believe every viral thing you come across on the Internet, Crayola is warning customers not to use its colored pencils as makeup after some beauty bloggers posted tutorials on how to soften the drawing tools and use them as eyeliner.

Though it might be tempting to save a few bucks and head to the art supply aisle instead of the cosmetics area of your local drug store, Crayola is warning against the practice of using its pencils as makeup.

Some bloggers have advised softening colored pencils in water and spreading the color on eyes or lips as they’re non-toxic, but Crayola notes that while its products are safe for use by kids who might say, chew on them, they haven’t been tested for use as makeup.

“As the manufacturer of children’s products, safety is our top priority at Crayola,” the company said on its website. “Although our products are nontoxic, we do not recommend using them to make lipstick, eyeliner or other make-up and strongly discourage their use in this manner. They are not designed, tested or approved for this purpose.”
