A new study claims five of six sunscreens inadequately block harmful rays or contain substances with “significant” safety issues
The Environmental Working Group plans to report today that just 128 of 785 sunscreens studied offer “very good sun protection with ingredients that present minimal health risks.”
The group gives 620 other products “Caution” ratings and lists the remaining 37 as “Avoid.”
