How quickly do dangerous substances from sunscreen penetrate the blood

When planning to go on nature or on vacation to the sea, we will certainly take sunscreen with us, because the skin of urban inhabitants, not used to the abundance of ultraviolet radiation, needs protection. The modern cosmetics industry offers us a wide range of various creams, both for adults and for children. But, as shown by the results of a recent experiment, sunscreen can be not only useful, but also dangerous. The chemicals in its composition are able to penetrate through the skin into the blood and circulate through our body.

Sunscreen alone is certainly beneficial. According to doctors, this cosmetic product not only protects the skin from sunburn, but also prevents premature aging and various skin diseases. But if no one disputes the positive effect on the skin, then the experts have questioned the general safety of such products for the whole organism. And, as American scientists found out, the suspicions were not in vain: some substances from the cream were fixed in the blood of the participants in the experiment.

The study involved 24 people who for 4 days actively used various means of protection from ultraviolet rays. The subjects applied the cream 4 times a day, and already on the second day all dangerous substances were discovered in their blood, for the sake of which, in fact, the experiment was conducted. The concentrations of substances such as oxybenzone (benzophenone-3 or diphenylketone), mexoril, octocrylene and avobenzone exceeded the safe standards recommended by doctors.

The authors of the study note that the results obtained require additional verification, as well as a more detailed study. But one thing is clear: the chemicals that make up the protective equipment, successfully penetrate the body and are fixed in the blood.

It is worth noting that this is not the first warning of scientists regarding the harm of sunblock. Russian experts conducted experiments with agents that included avobenzone, and found that this substance, when exposed to ultraviolet and chlorinated water, decomposes into a number of aggressive organic compounds. Such chemical transformations can occur if you swim in the pool on the street.

As for another frequent component of protective creams - oxybenzone, then there is already a dossier on it with evidence of its harm. Studies have shown its connection with disorders of the endocrine system, and there is also evidence of its effect on skin diseases.

The above information eloquently suggests that sunscreens and their constituent components are not well understood and do not have the necessary safety for humans. And given the fact that these products, when released into the water, cause significant harm to natural ecosystems, it becomes obvious that this branch of cosmetology is in urgent need of innovative safe developments.
