FDA released a warning about temporary tattoos. Temporary tattoos that use black pigment called “black henna” often utilize coal-tar hair dye with p-phenylenediamine (PPD) to extend the life of tattoo. PPD is known to cause skin reactions in people and by law is not allowed in cosmetic products that are applied to skin. Have your patients ever consulted you about permanent or temporary tattoos? How often have you seen adverse effects related to body art?
