Spray Tans - Experts Raise Questions as Industry Puts Out Warnings: "genetic alterations and DNA damage"
2012 06 12

By Mark Greenblat and Gitika Ahuja | GoodMorningAmerica



The active chemical used in spray tans, dihydroxyacetone (DHA), has the potential to cause genetic alterations and DNA damage, according to a panel of medical experts who reviewed 10 of the most-current publicly available scientific studies on DHA for ABC News, including a federal report ABC News obtained through the Freedom of Information Act.

Six medical experts in areas ranging across the fields of dermatology, toxicology and pulmonary medicine said they "have concerns" after reviewing the literature and reports about DHA, the main chemical in the popular "spray-on" tan, which has conventionally been referred to as the "safe" alternative to tanning under ultraviolet lights.

None of the reviewed studies tested on actual human subjects, but some found DHA altered genes of multiple types of cells and organisms when tested in different labs by different scientists after the chemical was approved for use in the consumer market.

"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 -- that is, getting into the bloodstream."

Panettieri, like all the experts ABC News consulted with, said more studies should be done. He emphasized the available scientific literature is limited. Still, he said, he has seen enough to say the warning signs of serious health concerns exist.

Sunscreen Causes Cancer? What You May Not Know About Sunscreen
Patrick Gallagher | NaturalSociety.com

Who would think that sunscreen causes cancer? It has been only a fairly recent development, but it still could cause some serious shock and awe when everyone figures out that conventional sunscreen found in drugstores nationally could be a potential risk factor for skin cancer. Sunscreens are made to protect and help your body, so why are we finding out that sunscreen causes cancer? It could be simply widespread ignorance, or it could be that the FDA has kept this secret under wraps for at least a decade.

Sunscreen Causes Cancer?

Studies conducted indicate the dangers of certain chemical compounds within sunscreen could be causing a variety of skin damaging ailments, especially when reacting with the sun’s intensive heat. Though the FDA had supervised and funded the studies showing key ingredients related to vitamin A as carcinogenic, they knowingly prevented the information from being released to the public whatsoever – up until recently. The synthetic vitamin A compound found in many sunscreen brands contain retinol and retinyl palmitate, both found to react negatively in the sunlight, becoming toxic to the system. This isn’t to be confused with the health-enhancing vitamin A that is found in many foods – it is a purely synthetic and ultimately useless ingredient. When combined with the extensive use over time, this kind of sunscreen can lead to skin damage in its users.

These aren’t the only things to be worried about when applying your doctor-recommended photocarcinogen, though. Oxybenzone and other vague mystery chemicals are found amongst a wide variety of name brand sunscreens, with many of these having yet to be proven as safe to use at all. About 8 percent of all sunscreens have been quality tested by the Environmental Working Group (EWG) to be both safe and effective for the intended use, whereas the other 92 percent contain at least one (if not many more) of the ingredients designated as detrimental for human use, further adding to the worry if sunscreen causes cancer.
