According to a new study published by the JAMA Network, many of the chemicals found in sunscreen are absorbed into the bloodstream after just one day of use. The study also found that the concentration of these chemicals in the bloodstream continued to rise with each day of use. The bloodstream was found to be clear of these ingredients after a full twenty-four hours of discontinued use of the sunscreen.
The chemicals that were found to be absorbed into the bloodstream were identified as avobenzone, oxybenzone, ecamsule, and octocrylene, which are all compounds that the FDA has stated require further testing and research to verify their safety. However, even with these questionable compounds being absorbed at high levels into the bloodstream, experts state that individuals should still continue to use sunscreen regularly.
While the FDA and other researchers have confirmed the need to perform further tests on the ingredients found in most sunscreens, the complications that can arise from avoiding sunscreen use can be deadly. According to the Skin Cancer Foundation, skin cancer is diagnosed among Americans more than every type of cancer combined. As one of the most common types of cancers, melanoma should still be actively prevented despite the possible complications of sunscreen.
