We might be absorbing more sunscreen chemicals into our bloodstream than is safely recommended, federal health officials say. Investigators from the US Food and Drug Administration (FDA) tested six of the main active ingredients in sunscreen lotions and sprays. They found that all of the chemicals had higher concentrations in the blood than the FDA's threshold. One of the ingredients had a concentration that was 360 times greater than what is recommended by the agency. Researchers found that all of the chemicals had concentrations greater than 0.5 nanograms (ng) per millimeter (mL) of blood plasma, which is the FDA's threshold.
