I would "spot test" an inconspicuous place on your face (is there such a thing!?!? lol) just like hair dye suggests. If your face normally isn't sensitive and doesn't break out/rash easily, it will probably be fine. I'm sure it's just a strength issue with the product and for most people, would cause a rash on their face (more sensitive area). Just don't swallow or paint your pupils with it and I'm sure it will be fine
