Temporary tattoos seem so fun and innocuous. But as the saying goes: It’s all fun and games until someone gets hurt.
The U.S. Food and Drug Administration (FDA) has issued a warning about temporary tattoos, also known as “henna” tattoos. There have been reports of severe skin reactions, sometimes leading to permanent scarring.
“Just because a tattoo is temporary it doesn’t mean that it is risk free,” says Linda Katz, M.D., M.P.H., director of FDA’s Office of Cosmetics and Colors. Temporary tattoos typically last from three days to several weeks, depending on the product used for coloring and the condition of the skin. Unlike permanent tattoos, which are injected into the skin, temporary tattoos marketed as “henna” are applied to the skin’s surface.
Some consumers report reactions that may be severe and long outlast the temporary tattoos themselves. Reported problems include redness, blisters, raised red weeping lesions, loss of pigmentation, increased sensitivity to sunlight, and even permanent scarring. Some reactions have led people to seek medical care, including visits to hospital emergency rooms. Reactions may occur immediately after a person gets a temporary tattoo, or even up to two or three weeks later.
The worst problems seem to occur after getting a temporary tattoo with the so-called “black henna.” Inks marketed as black henna may be a mix of henna with other ingredients, or may really be hair dye alone. The reason for adding other ingredients is to create a tattoo that is darker and longer lasting, but use of black henna is potentially harmful.
That’s because the extra ingredient used to blacken henna is often a coal-tar hair dye containing p-phenylenediamine (PPD), an ingredient that can cause dangerous skin reactions in some people. Sometimes, the artist may use a PPD-containing hair dye alone. Either way, there’s no telling who will be affected. By law, PPD is not permitted in cosmetics intended to be applied to the skin.
Some examples of problems reported to the FDA include:
If you have a reaction to or concern about a temporary tattoo or any other cosmetic, in addition to recommending that you contact your health care professional, FDA asks you to contact MedWatch, the agency’s problem-reporting program. You can also call 1-800-FDA-1088 to report by telephone.
