DHA Media

Recent news stories have said that spray tanning "may pose health risks". We would like to talk about these issues straight up. Bronze Biologic has been a pioneer in the spray tanning industry since 2004. We manufacture our own specific brand of sunless tanner. We have always maintained the highest health and safety standards for our clients. We are listening carefully to all the newest data and we would like to give you our thoughts on the information.

When we receive our raw materials from our suppliers to manufacture sunless tanning products, they come with a MSDS (Manufacturers Safety Data Sheet). This is a form that accompanies chemicals when they travel, in case of any spill on the way. On the MSDS for Bronze Biologic DHA it says "no mask or gloves required." Please see attached MSDS sheet for DHA.

DHA has been approved for sunless tanning since the 1950's. Once spray tanning evolved, some reports mentioned that DHA could cause sensitivity to the eyes, nose and mucous membranes. DHA had widely been reported not to be carcinogenic. For the average client who comes in a few times a year, or even once a week, the exposure is so minimal. The average client just closes their eyes and in eight years we have never had a client complain of any eye irritation.  Our unique precision needle spray system atomizes the spray for an extremely fine mist that when done correctly provides minimal overspray. While many companies use and list many potentially harmful ingredients in their formulas. We do not!!!! Ever!!!  While many airbrush compression or mechanical spray systems permeate the air with lots of overspray and require ventilation systems and circulation fans we do not ever!!! When sprayed correctly with our system a small amount of solution should be used and only sprayed on the skin ( not in the air) In fact we spray people with blond hair and white shirts and get none in the hair on the clothing in our demonstrations.

Every year we are told that something or other "may" pose risks. A great example is hair dye: where you are putting chemicals right on your scalp and leaving it to soak in for 40 minutes. On my desk as I write I have two tubes of toothpaste - Crest Kids and Colgate, something probably every family uses everyday. On the kids toothpaste it says, and I quote: "Keep out of reach of children 6 and under. If more than used for brushing is swallowed, get medical help or contact a poison control center right away." Fluoride is highly carcinogenic yet we put it in our mouths at least twice a day. Every time I go to a restaurant I seem to be assaulted by wet staff spraying Windex on tables around me. Ammonia is another highly toxic substance we inhale every day. In life there are risks all around, and I personally think that DHA, which for years has been reported as not carcinogenic, is far less of a hazardous substance than hair dye or toothpaste. Like everything in life, the smart thing is to use moderation and take steps to protect yourself. If you are worried about sensitivity or inhaling, use the goggles, nose plugs and paper underwear. Even if you come in to get sprayed on a weekly basis your risk is so minimal compared to the many environmental hazards you face every day. Using deodorant is also supposed to be a hazard.

At Bronze Biologic we have always thought carefully about what we put in our product and have always been diligent and vigilant to not put any questionable or potentially harmful ingredients in any of our formulas. We have always been cognoscente that we were spraying something into the air that could be inhaled. For that very reason we never offered sprays to prep the skin or to seal the tan or any potentially harmful ingredients. To us, when we heard other companies offered that, we thought it was a bogus way of charging clients more without respect for safety. Our DHA is made for us, we have small batches of very fresh DHA, which is why our product doesn't smell, and if you look at the ingredient list, which you may see on our website, brochures, point of sale and clearly on our label, the ingredient list is simple. We strongly believe that we have a safe product because we have been using it for 8 years without incident and have meticulously sourced and researched the ingredients we use. We care deeply about the safety of our clients and staff and we listen carefully to all the latest recommendations. Every day we are told to worry about something new.  We have every safety measure in place so you can have a worry free experience and continue to enjoy a safe tan. In our opinion other ingredients found in spray on tanning products can and do contain potentially harmful ingredients (like FDC colors and dyes, propylene glycol, benzyl or propyl alcohol , parabens , aluminum silicate and so much more) If you research the MSDS sheets on these products you would not even allow them in your house let alone on your skin and in the atmosphere.

DHA is dihydroxyacetone, a carbohydrate (monosaccharide sugar) it comes from plants, normally sugar beets or sugar cane.

DHA has not been shown to have any long-term or damaging effects on the skin at all. It only absorbs into the upper surface skin layers, never even penetrating into the actual living tissue underneath. It reacts with the dead cells, and the amino acids on skin surface.

It absorbs much like makeup, body lotions, and other skincare cosmetics and body care products.

Because it only reacts with the dead surface skin cells, which flake off everyday, it is also completely temporary. As the skin cells regenerate and old ones fall - it takes the sunless tan and DHA with it.

It does not seem to absorb into the deeper skin layers, blood stream, or connective tissues. The molecular structure is too large to penetrate into deeper tissues. It has never been shown to buildup in tissues, organs, or liver. Blood stream and urine and liver tests have never shown it to deposit into the bloodstream with continued use.

It has been FDA approved for skin use for over 30 years, a search on the FDA website shows that there is no documentation of any long-term negative effects ever reported. They even added it permanently to their database, as a product that is considered "safe" for skin use. It was actually used as early as the 1920's as a Vitiligo treatment for children. It was marketed in the 1960's as a sunless tanner.

Numerous tests have been done on the product since that time, and no dangers are noted.

It can cause irritation in people that are sensitive to it, but the ratio is less then 1%, which is the same ratio for any other cosmetic products such as perfumes, dyes, etc. So it is well within normal ranges for safe public use.

DHA has been used as a diet supplement in sports nutrition and it is non-carcinogenic. Testing has further shown that DHA is less toxic than aspirin, caffeine, and even common table salt.

The MSDS data sheets for DHA show no hazards associated with it, even when working with it in a 100% formulation in a factory environment, where it is worked with daily, for an 8 hour shift.

DHA has a health risk rating of "0-Minimal" and is not considered a toxic material. No special masks, or hand and eye protection are required. And OSHA standards do not qualify it is a carcinogenic, or toxin that needs special handling or precautions.

It has been approved by the American Academy of Dermatology as a skin and body safe UV tanning alternative, and recommended by various medical associations. The American Cancer society, does not list DHA as a problem product in any of its information.

The main concern people have with DHA right now, is more manufacturers are adding ingredients to cosmetics to allow them to penetrate deeper and deeper into the skin. And in theory, at some point, it (DHA) could “possibly” penetrate deep enough to be a problem.

But that does not seem to be the case so far, and if that point is ever reached, it would be a problem for ALL cosmetics and body care products. Because other products such as moisturizers, anti-aging lotions, makeup’s, etc. also use the same technology – so all cosmetics have the same potential to penetrate deeper.

So it could then be a problem with ANY OTC (over the counter) product, not just DHA. :)
On a side note- many people that become regular sunless tanner users, often find that skin because much healthier and fresh looking over time.

This is because, most sunless tan product users, begin to take better care of the skin, which improves the look and health of the skin making the skin look better - both "tanned" and untanned.

Regular exfoliation, and moisturizing, switching to milder skin care products, increased sunscreen use, and less UV exposure all create healthier skin. Which create a "prettier" tan. :)

The recent negative press that has been aired in the media is simply a very clever but uneducated scare tactic that has no scientific backing or validation of any kind facilitated and funded by the UV tanning lobby which is a bias source that stands to profit greatly from creating doubt about the safety of spray tanning. The sources are not credible, uncontestable, funded by lobbyists and even unclear and misleading in the message. They clearly state the literature is limited, and no studies have been done on humans, and that overexposure could be a problem, and statements like has the potential are unclear and misleading but there is no proof and absolutely no validation of truth or even factual in any statement that was made.

Here is an except from an interview aired

"The active chemical used in spray tans, dihydroxyacetone (DHA), has the potential to cause genetic alterations and DNA damage"
"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.

"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."

It seems they are referring to this specifically being related to inhalation during spray tans. And of course everyone is going to be in a panic and terrified of getting a spray tan now.  


Inhalation concerns are not really new. Anything inhaled, especially repeatedly could be a problem.

This is not just limited to DHA - hair spray, body mists "sprays" deodorant sprays, sprays used to apply a heat protective finish to the hair, aerosol sunscreens, perfumes etc. All have the exact same risks, issues, dangers.

Not sure if it was addressed in above comments, but as Clara has mentioned on here, something as innocuous as bits of hair breathed in over and over repeatedly is the cause of a lung disease called "Barbers Lung" - seen in barbers who cut hair for years, and breath in hair fragments daily.

Best approach, let clients know - this is all "common sense" "better safe than sorry" suggestions. It is optional, if a client wants to use protective devices or not.

Pickup some breathable nasal filters (available online at a number of sources including ebay) client can breathe through, protective paper undergarments, lip balm for lips, and eye goggles.
Provide great ventilation in your facility. :) Have them available for clients that want to use them

Provide client waivers for every client to sign to protect your business from all kinds of stuff people sue over. (I spoke to a tech recently and a client wanted to sue her because she sat on her toilet with her developing tanning spray on and stained the toilet seat)

This is all "suggested" "common sense" measures, that allows those who are concerned to protect themselves until further results can be presented. Its not a law.

And know that results on intact skin cells, is a different thing then results on live loose tissues in a petrie dish.


"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."


I watched the interview with the doctor quoted above, and one thing stood out. His conclusion wasn't that sunless sprays weren't safe, it was, "It's time to pursue this question in a more rigorous fashion, and really answer the issue, is it safe or not." And yet that became the headline "DHA Health Risk." What the doctor actually said: there should be more studies.

If additional studies are done, the first thing that needs to be determined is: does any DHA actually get into the body during a spray session, and would it be enough to cause harm? When I'm in a sunless tanning booth for 60 seconds, I don't take in big lungful’s of air. It seems the doctor is aware consumer exposure is minimal, because the article says he's concerned about people working around sunless spray all the time, not consumers who occasionally get a spray tan.

A New York Mag article says the data the doctor is concerned about comes from a study conducted on "nonhuman cells" in laboratories. Putting DHA on nonhuman cells in a laboratory doesn't tell us anything about this critical point: do people actually breathe in a bunch of spray? If they do breathe it in, is it enough to cause harm? Is it absorbed by the lungs? Does it enter the bloodstream?

Whenever someone is quoted about the dangers of people breathing in a sunless spray (as has happened many times in the last decade), they only worry about the DHA in the product. What about the hundreds of other ingredients in sunless sprays? Why is it only DHA that is cause for concern?

I believe the answer is threefold:

1) Studies in a more "rigorous fashion" would require testing every ingredient used in sunless tanning sprays, not just DHA. That's hundreds of ingredients. How much gets breathed in, and what it does once it's in the body (absorbed, or eliminated), would have to be established for every single ingredient. The expense would be astronomical.

2) A necessity for such studies has not been demonstrated, so no one has funded them.

3) This is the very important bit: Negative publicity about sunless tanning, especially sunless tanning booths, is rapidly picked up by the media due to the lobbying power of the UV tanning industry. A key source for ABC was Joe Levy of the International Smart Tan Network, who "presented ABC News a critique of one of the more recently published studies that concerned experts. The study, published in the scientific journal "Mutation Research" in 2004, found that DHA as used in sunless tanners "damages DNA." Levy provided ABC News with a letter written by a Merck KAag scientist in late May 2012 criticizing the study."

Leaving aside the fact that the "more recent" article is eight years old: In a shocking oversight, ABC does not disclose what the Smart Tan Network is: a powerful lobbying group for the UV tanning industry, which bankrolls the UV industry's fight against restrictions on UV tanning, such as prohibiting UV tanning for anyone under 18. Sunless tanning booths are seen by some in the UV tanning industry as a threat to UV profits. In short, Levy could benefit financially from negative publicity about DHA and spray tanning. ABC's article should have revealed it was using a source with a bias; its failure to do so makes me wary of the rest of the content. The Smart Tan Network's involvement in the story is why the focus is on DHA, not on any of the other hundreds of ingredients in sprays; DHA is what the UV industry worries about!

But I agree with the doctor that additional studies are needed. What is a must is a study on how much, if any, spray is breathed in. The test would not require human or animal exposure; it could be completely mechanical, measuring the concentration of spray in the air (another variable that would have to be taken into account; not all sunless booths or airbrushes are the same in that regard). Based on the concentration, and on the time period of exposure, the study could determine how much spray could potentially be breathed in. Until the level of exposure is known, it's not possible to determine if there is a potential for harm.
