Meanwhile, the FDA stresses that people should continue to use sunscreen and follow other sun safety practices, such as wearing protective clothing, hats, and sunglasses. More research is needed to confirm the study results and determine what effects, if any, absorption might have on a person’s health. Oxybenzone showed up in the blood in far higher concentrations than the other ingredients. One pilot study conducted by FDA scientists tested four chemical sunscreens and found that all of the chemicals tested (avobenzone, oxybenzone, octocrylene, and ecamsule) were absorbed into the blood at levels higher than those the FDA recommends for chemicals that have not been tested for toxicity. The main concern with chemical sunscreens is their ability to enter the bloodstream. Mineral sunscreen is effective right away. “Otherwise, you could get burned while the sunscreen is being absorbed,” said Evelina Ingersoll, APRN, a certified advanced practice registered nurse at Water’s Edge Dermatology.
