High levels of sunscreen chemicals absorbed into bloodstream
Concentration of one chemical was 700% higher than guidelines, says US FDA

The active ingredients of commonly used sunscreens end up in the bloodstream at much higher levels than current guidelines allow for, according to a small study by the US Food and Drug Administration (FDA).
Researchers tested four sunscreens on 23 volunteers, including sprays, lotion and cream, applied to 75% of the body four times a day over four days.
