Jacob Sullum reports on some bad news from a recent Sunscreen Screening:
The Environmental Working Group rates 786 varieties of sunscreen available in the U.S., based on both effectiveness and potential health hazards. It concludes that “only 17% of the products on the market are both safe and effective, blocking both UVA and UVB radiation, remaining stable in sunlight, and containing few if any ingredients with significant known or suspected health hazards.”
