Oh, hey: Now spray tanning might give you cancer.
The chemical that actually darkens skin, dihydroxyacetone or DHA, was only approved by the Food and Drug Administration for external use in self-tanning lotions. The FDA does not recommend spray-tanning and says DHA should never be inhaled or ingested. Scientists say that more research is required, but that there is evidence that DHA may cause problems when it is inhaled. And inhalation is nearly impossible to avoid when microparticles are being sprayed through the air at close range in an enclosed space.
"I have concerns," said Dr. Rey Panettieri, a toxicologist and lung specialist at the University of Pennsylvania's Perelman School of Medicine. "The reason I'm concerned is the deposition of the tanning agents into the lungs could really facilitate or aid systemic absorption ó that is, getting into the bloodstream...These compounds in some cells could actually promote the development of cancers or malignancies, and if that's the case then we need to be wary of them."This is of potential concern not only to people who may get spray tans ó just think of the Kardashians! ó but to salon workers who experience prolonged exposure to the airborne spray.
