Tanning creams left over from last year may contain carcinogens. These findings were presented by French scientists after research. The octocrylene sunscreen contained in the creams is converted by exposure to the sun into oxybenzone (benzophenone-3, which absorbs and reflects UV radiation – Ed.).
This substance can cause rashes, inflammation, hypersensitivity, and cancer. It also affects the thyroid gland and genitals, damaging the secretion of hormones from the endocrine glands. The researchers urged manufacturers to scrap the sunscreen.
French microbiologists from the Sorbonne and scientists from the national research agency CNRS examined about a dozen popular sunscreens and day creams in France and artificially aged them. Result: After a year, the sunscreen filter has been decomposed into benzophenone molecules – a substance that penetrates the skin can cause serious consequences.
One of the researchers, Didier Steen, explains: “If benzophenone gets on the skin, it can cause rashes, inflammation, and liver cancer or lymphoma. This was shown by experiments carried out on animals. This molecule affects the thyroid gland and reproductive organs. “
Scientists have researched products from renowned companies such as Garnier, Uriage, Bioderma, la Roche Posay, Cosmi or L’Oréal. In some of them, the limit of 10 milligrams of benzophenone per kilogram exceeded the norm in a year.
Research critics point out that rodent studies use a much larger volume of solar filters than humans use.
