- The active ingredients of commonly-used sunscreens end up in the bloodstream at much higher levels than current U.S. guidelines from health regulators and warrant further safety studies, according to a small study conducted by U.S. Food and Drug Administration researchers and published on Monday.
The study of 23 volunteers tested four sunscreens, including sprays, lotion and cream, applied to 75 percent of the body four times a day over four days, with blood tests to determine the maximum levels of certain chemicals absorbed into the bloodstream conducted over seven days. The results in no way suggest that people should stop using sunscreen to protect against the sun’s harmful ultraviolet rays, researchers said.
David Andrews, a senior scientist at the nonprofit health and environmental advocacy group Environmental Working Group, called for thorough testing of sunscreen ingredients.
