SAN DIEGO -- Everyone has been told all about the dangers of too much sun, but there is a new potential danger for tan lovers in the privacy of a booth.

It's every tan fan's dream -- a perfect bronze in 45 seconds without all those harmful UV rays.

It's called the mystic or magic tan, literally tanning with a fine chemical mist.

"I just thought it would be convenient. I didn't have any health concerns," said mystic tanner Megan Goodman.

Like many sunless tanners, Goodman assumed she was safe.

She didn't know the FDA issued a warning about the ingredient in these spray on tans -- a chemical called DHA.
