Sunscreen is a risk?

Chemicals from sunscreen in our body

Sun cream is the most popular medium, to Sunburns, and therefore, also against skin cancer. Lately, concerns were raised, however, that in some sunscreens chemicals, the effects on our body. A recent study has now demonstrated clearly that certain ingredients can get from sun cream through the skin into our bloodstream. The consequences are, however, currently little is known.

In a recent study by the American Food and Drug Administration (FDA) has proven that the ingredients Avobenzone, oxybenzone, Octocrilen and Mexoryl SX (Ecamsule), which are located in many sunscreen products that pass through the skin into the bloodstream. The results of the study were recently presented in the journal “JAMA”.

The expiration of the study

For the study, 24 adults participating in four groups. Each group received a different combination of commercially available creams, Lotions, and Sprays for protection from the sun. The test subject then had to RUB over a period of four days, four times a day, 75 percent of the surface of the body with sun cream. During the test, and in the following days, the blood and Urine of the Participants checked.

Sunscreen chemicals in the blood

The researchers from the FDA found in all groups of measurable concentrations of the chemicals Avobenzone, oxybenzone, Octocrilen and Mexoryl SX in the blood of the Participants. The concentration was so high that, according to the safety regulations of the FDA, further studies causes not have to be, since a current is safe to use is clearly. For example, could be from the first day, plasma concentrations of the chemical Avobenzone measured, which were above 0.5 nanograms per Milliliter of blood. This value remained about three days, after no cream was used. The chemicals oxybenzone and Octocrylene similar concentrations. These were, however, only over the period of the application.

Impact is currently uncertain

“The demonstration of a systemic Absorption significantly higher than the FDA Directive, does not mean necessarily that these ingredients are unsafe,” write the researchers in an Editorial to the study results. Nevertheless, the study raises many important questions about sun-protection products, which must now be clarified. The benefits and risks, as well as the process for the production should be of Supervisory authorities, professional organisations and clinical researchers re-evaluated. First and foremost, is it important now to whether the systemic Absorption of sunscreen products poses a risk to human health.

How intense the sun can be tested for protection?

Many users of sunscreen products from that company, the sun have carried out to restore protection products and distribute basic studies to establish the safety and efficacy of their products. But unfortunately this is not so. According to the FDA, the creams are not medicines. You have to go through any standard of drug safety tests, and in spite of decades of use there are no data to systemic concentrations in the blood. In addition, there is as yet no adequately designed studies have determined the optimal sun protection dose required to achieve a balance of risk and Benefit in the prevention of skin cancer.

Sun protection-manufacturers want to maintain the Status quo

The FDA reports of delays in the investigation of this matter. The American authorities have been trying to their own several times, unsuccessfully, to move the sun cream industry to conduct more accurate studies. You gave no, or insufficient data. For this reason, the FDA is now conducting the necessary investigations. The pressure on manufacturers is increasing also, because the FDA has already threatened to take the sun protection products with questionable content from the market if the manufacturer agree to the November 2019 ready to enlightenment.
