According to a new study from Consumer Reports, 43 percent of sunscreen products do not live up to the sun protection factor (SPF) claims on their bottles.
Consumer Reports found that 13 out of the 35 sunscreen lotions tested had an SPF of less than 30, despite claiming to have at least an SPF of 30 on their labels. The majority of products that fell short on their SPF numbers did so by 10 to 15 points. However, some products were labeled as SPF 50, and were only found to have an SPF of 8.
The study found that sunscreens with active chemical ingredients like avobenzone and ecamsule performed better during testing than those with natural ingredients like zinc oxide.
