The ABC and CBS networks have reported that DHA may wreak havoc on your DNA. In a nutshell, the report is stating DHA (the chemical responsible for turning your skin brown) may alter the genes of different cells and organisms. One doctor states, "These compounds in some cells could actually promote the development of cancers or malignancies," he said, "and if that's the case then we need to be wary of them." The panel of experts state they are especially concerned for repeated users of the product and those in higher-risk groups such as pregnant women or young children.
Dr. Goldman states, "What we're concerned about is not so much that reaction that creates the tanning, but reactions that may occur deeper down with living cells that might then change DNA, causing a mutation and what the possible impacts of that might be," she said. "I'd be very concerned for the potential of lung cancer."
Researchers should, however, not just be concerned about cancer, but other health effects such as birth defects, especially if a woman who was pregnant was spray tanning and allowing the mist to get inside her body, Goldman said.
What the News ISN'T Telling You:
While there may be some concerns with ingestion of DNA, and the fact that ingestion of any chemical can have adverse affects on the skin or in your body, let's not forget the parabens, ureas, phthalates, preservatives, dyes, etc.. in the food and body care products most Americans consume everyday!
Most of the parabens, ureas, dyes phthalates are listed to be used as industrial chemicals. These chemicals are linked to infertility, birth defects, liver, kidneys and lung damage, and hormone imbalances.
Hundreds of animal studies have demonstrated this to be true. Many of these chemicals are absorbed through the skin, but can also be inhaled as fumes, ingested when they contaminate food or when children bite or suck on plastic toys, and are inadvertently directly administered to patients from PVC (polyvinyl chloride or vinyl) medical devices.
According to one study carried out by the Centre for Disease Control in the USA, five percent of women of reproductive age in the USA, an estimated two million women, may be getting up to 20 times more of the phthalate DBP than the average person in the population. The highest exposures for women of childbearing age were above the federal safety standard, creating a risk of reproductive birth defects, according to animal studies considered relevant to humans. WHY IN THE WORLD DO WE STILL USE THESE PRODUCTS?
What is DHA... really?
Dihydroxyacetone (DHA) is derived from sugar beets or cane sugar and is a key active ingredient for natural self-tanners. The skin-browning effect is the result of a nontoxic chemical reaction between DHA and the amino acids which are part of the keratinous layer of the skin’s surface, much like the browning effect in food caramelization. The resulting color is called melanoidins, similar in color to the melanins our bodies produce naturally when exposed to UV rays. DHA creates a more natural looking tan, and fades more evenly, than chemical tanners and is now considered the most effective sunless tanning ingredient. It is also considered the safest form of tanning over chemically-derived self-tanners and sun exposure.
Additonal Information from ABC & FDA:
Anything you put on your skin is absorbed in 26 seconds. These lotions, serums, facial cleansers are being absorbed into your blood stream. Most of these items contain those chemicals listed above.
They concluded: "This leaves about 11 percent of the applied DHA dose absorbed remaining in the [living] epidermis and dermis."
Four years after the report was issued, the FDA wrote a follow-up paper based on the same data, concluding that "probably" only 0.5 percent of each application of DHA becomes "systemically available," meaning distributed throughout the body after reaching the bloodstream.
The agency concluded that 0.5 percent of an applied dose of DHA was poor absorption, and no further testing was done to check for actual toxicological impacts on the human body. The thinking was that because only a little bit of DHA entered the bloodstream, the health risk would be very low.
Toxicity: Dihydroxyacetone (DHA) is generally classified as being a low to moderate hazard depending on product usage and how the DHA is sourced. DHA has been approved for external and cosmetic use by the FDA, the Canadian Health Ministry, and most of the EU member nations. DHA-based sunless tanning has been recommended by The Skin Cancer Foundation, American Academy of Dermatology Association, Canadian Dermatology Association and the American Medical Association.
