In an evaluation of CDC-collected exposure data for American children, researchers found that adolescent boys with higher oxybenzone measurements had significantly lower total testosterone levels (Scinicariello 2016).

Oxybenzone causes allergic skin reactions (Rodriguez 2006), behaves like an endocrine disruptor in many studies (Krause 2012, Ghazipura 2017) and is potentially of greater harm to children (FDA 2019). It is readily absorbed through the skin (Matta 2019, Matta 2020) and the Centers for Disease Control and Prevention found it in nearly all Americans, with higher levels in those who report applying sunscreen (Zamoiski 2016). The most worrisome sunscreen active ingredient is oxybenzone, according to publicly available scientific research. + = evidence – = no or weak evidence The science on ingredient toxicity Sunscreen products typically include a combination of active ingredients, except for those formulated with zinc oxide.įDA 2019 proposed classification as safe and effective This table outlines human exposure and hazard information for eight common FDA-approved sunscreen chemicals, often referred to as active ingredients because they provide ultraviolet, or UV, protection. We have even more concerns about ingredients such as oxybenzone, which have been linked to hormone disruption by numerous studies. This constant exposure to sunscreen chemicals raises concerns, especially because there is not enough safety data for most ingredients. In addition, it’s possible for sunscreen users to inhale ingredients in sunscreen sprays and ingest some of the ingredients they apply to their lips, so the ingredients must not be harmful to the lungs or internal organs. Previous studies detected many sunscreen ingredients in breast milk and urine samples (Schlumpf 2008, Schlumpf 2010). The ingredients oxybenzone, octinoxate, octisalate, octocrylene, homosalate and avobenzone are all systemically absorbed into the body after one use (Matta 2019, Matta 2020), according to studies published by the FDA, which also found that they could be detected on the skin and in the blood weeks after no longer being used (Matta 2020). use them at concentrations that far exceed the European Commission’s recommendations. sunscreen manufacturers are legally allowed to use these two chemicals at concentrations up to 6 and 15 percent, respectively, and hundreds of sunscreens manufactured in the U.S. It found that the levels of two of them were not safe in the amounts at which they are currently used, and proposed a concentration limit of 2.2 percent for oxybenzone and 1.4 percent for homosalate. Within the past year, the European Commission has published preliminary opinions on the safety of three organic UV filters, oxybenzone, homosalate and octocrylene. But in the past year, numerous new studies have raised new concerns about endocrine-disrupting effects from three other ingredients: homosalate, avobenzone and oxybenzone.
In 2019, when the federal Food and Drug Administration – the agency that governs sunscreen safety – proposed its most recent updates to sunscreen regulations, it found that only two ingredients, zinc oxide and titanium dioxide, could be classified as safe and effective, based on the currently available information.
This includes toxicity testing for irritation and skin allergies, as well as testing for skin absorption and the potential to cause cancer, disrupt the hormone system and cause harm during reproduction and development. The companies that make and sell sunscreen ingredients and products should test them thoroughly for potential short-term and long-term health effects. Sunscreen products are intended to be applied to the body every day, for a lifetime.
