Some beauty bloggers experiment with the strangest products. Some times the urge to be creative is stronger than common sense.
Just because something is non-toxic does not mean it is safe to use. Lemon juice, baking soda, walnut shells, jalapenos, and hot bacon grease are all technically non-toxic, but none of them should be on your face.
This hasn't stopped a huge movement on beauty blogs, YouTube, Pinterest, Instagram, and other platforms of using Crayola crayons to create lipstick and eyeliner.
The thought behind it seems logical, given that small children play with crayons and occasionally eat them with no problems. Just because you can eat them doesn't mean they are safe to apply to the most delicate skin on your body.
The ingredient list of Crayola crayons is propriety information, but includes waxes and colorants. However, none of Crayola's products are intended or tested to be used on the face as makeup. Products have to go through thorough testing to be manufactured and sold to the public, and even then there are terrible products that make it to store shelves.
Even Crayola has make a statement on their website to NOT use their products as makeup:
Kids may end up with crayon all over their face and body, but none of them are applying it to their waterline or melting it down for lipstick.
So what are the dangers? Eye infections, bumps, irritation, colorants traveling into the eye, corneal infections, problems with contacts and dry eyes. Of course not every person who tries crayons as lipstick or colored pencils as eyeliner is going to have a reaction, but is risking your vision worth it? There are plenty of inexpensive makeup lines that have been tested for these risks already.
Put down the colored pencils and don't risk your health!
