The link above is a complete study on DHA tanning. Tons of info.

Some info from the study:

Quote:

According to Draelos et al., DHA has low toxicity, both for ingestion and for application to the skin, with only few reported cases of allergic contact dermatitis. The low toxic effect is not further documented in the article (20). Other in vitro studies show that DHA is suspected of causing damage to the DNA (21,22,23). DHA induced a significantly increased number of type 3 foci in 3T3 fibroblasts, indicating in vitro neoplastic cell transformation (24). DHA has been found in the blood shortly after application to the skin (17). According to Petersen et al. (23) it is therefore possible that DHA may penetrate down through the stratum corneum and affect the DNA and proteins in other cells in the body.

Quote:

There is no data on inhalation of DHA. The US Magic Tan (5) have completed studies of the effects of exposure to self-tanning agents through inhalation, and on the eyes and mucous membranes, but they do not want to reveal the results.

Quote:

DHA is an ingredient in food and it has been approved for ingestion by the US Food and Drug Administration (FDA). In fact the health industry is the world's largest user of DHA. As DHA is a pyruvite or "fat-burner", it is used in many slimming products.

There is a ton to read.

I wonder what permanent effects that will cause?

Good find John.

Many times in the study it says they can't make claims either way without more testing. The main thing is there are no studies of long term effects or the effects of repeated exposure.

So would it be safe to believe that advertising your sunless spray tan products as "a safe alternative" to anything would be misleading based on these findings?

They should at least have a disclaimer.

"Safe Alternative to UV"

You should see the flyer some idiot sunless comnpany sent me yesterday. I won't even mention their name here because they are a nobody and I prefer them to stay that way. It was all about how I should offer the healthy tan at my salon. LOL
