In a new investigation of 952 name-brand sunscreens, the Environmental Working Group (EWG) found that 4 out of 5 sunscreen products offer inadequate protection from the sun, or contain ingredients with significant safety concerns.
Micronized and nano-scale zinc oxide and titanium dioxide in sunscreen provide strong UVA protection, and are contained in many of our top-rated products. Repeated studies have found that these ingredients do not penetrate healthy skin, indicating that consumers' exposures would be minimal.
