DHA - a potential threat to health?

Back in the 1990s there was, but not widespread information on genotoxicity and carcinogenicity of DCA. It has been found mutagenic effect of DHA on bacterial cells, e.g., Salmonella Salmonella: unknown facts And also on skin cells vyshey. Before there were the results of these studies, the employees of the cosmetic industry, which manufactures tanning, and even many dermatologists believed that DHA reacts with proteins only the outer protective layer of the skin - or stratum corneum. Since the cells that make up this layer, are already dead, and is about to disappear from the surface of the skin, it suggested that DHA does not pose any health hazards.

Later, however, scientists have found that the effect of DHA is not limited to the stratum corneum .  It was found that if the substance is applied to the skin in larger quantities, it can penetrate into the deeper skin layers, which consist of living cells .  Approximately 11% of the total amount of DHA incident on the skin is absorbed by living cells of the epidermis and dermis .  Four years after the report was published with these data, FDA has issued an opinion, based on the same information; According to him, "likely" (this word has been used in prison) systemic absorption occurs (distribution throughout the body after penetrating the blood) 0 . 5% of the total dose of DHA, which is applied to the skin .  Further research is needed to identify the risks associated with the toxicological effects of DHA per person, were not carried out .  It was concluded that since the bloodstream falls very small amount of this material, the health risks would be extremely low .

However, doctors say that the absorption of any substance in the living body tissue is a potential threat. The fact that any substance can penetrate into the bloodstream, should be sufficient reason to continue the study. Of particular concern of doctors it is the fact that potentially dangerous cosmetic products used by people at risk - pregnant women and young children. It is known that the participants of various beauty contests among children often "tan" just by the means of tanning. Often the skin four or five-year girls cover their own spray tanning mom. Of course, they want to make their daughters more beautiful, and sincerely believe that tanning is harmless.

Research

Other studies indicate that DHA can cause mutations or to modify the DNA of living cells. This occurs in the tissues located far deeper stratum corneum, and the consequences of these reactions are not at once. In particular, regular inhalation of DHA is associated with an increased risk of lung cancer Lung cancer - prevention is better than cure . Effects of DHA can also cause birth defects, especially if the woman uses a spray-tanning during pregnancy. DHA is a danger to workers and salons that every day inhaled the substance; many of them do not wear masks, continuing to believe that they are working with a hazardous substance. Meanwhile, the surface of the lungs is very high, it is designed to absorb oxygen and distribute it throughout the body. Lungs are doing the same with the infiltrating them with other substances, such as DHA: in contrast to the skin, no light at the protective layer, however, they absorb much more than 11% of them falling on hazardous substances.

In 2010, a report was published about the study safety of tanning aerosol containing DHA, commissioned by the European Commission .  According to the report, of DHA it is safe for consumers .  However, experts have found many shortcomings related to the preparation of this report .  In fact, it is an analysis of previously conducted studies, reports of which have not been published in scientific journals or reviewed by experts in the same field .  Much of the relevant studies conducted by companies involved in the production of means of tanning, or associated groups of scientists .  Moreover, the report of the European Commission are not considered published research in scientific journals, in which DHA was recognized hazardous substance .  Many experts say that for this reason, this report should not be considered complete and reliable .

Taking into account all the contradictions that cause the results of studies dihydroxyacetone, and what its effects on the human body remains virtually unexplored, organizations dealing with health on both sides of the Atlantic, in the foreseeable future is unlikely to ban the use of DHA, or at least to tighten the requirements for salon where used products containing this substance .  Fans of tanning from him hardly refuse, because the threats associated with DHA, look distant, and it is unclear how serious they are .  However, experts strongly recommend not to give up points and other remedies that may be used during the application of funds for tanning .  It is especially important to apply them pregnant women (preferably, of course, if they do not use tanning) .  Young children should not sunbathe at all - either in the sun or using creams and lotions .  Finally, good ventilation in the rooms beauty salons can help reduce the amount of DHA, which are inhaled employees .  And even with the good ventilation, they should wear respirators, otherwise you can advance in your city to look good pulmonologist - for the daily inhalation of any substance other than clean air, the body is unlikely to be grateful .
