Skin cancer is the most common cancer in the U.S., and the benefits of sunscreens outweigh potential risks from their ingredients. That said, animal studies have raised some concerns about what's inside these sunscreens.
Some chemical UV filters, such as octinoxate and oxybenzone, have been found to cause hormonal changes in animals; however, short-term research in people did not show any adverse effect. And one large animal study found that the inactive ingredient retinyl palmitate, one of a group of chemical compounds related to vitamin A called retinoids, may become carcinogenic when exposed to light. But that hasn’t been studied in people. Taking pills that contain a different type of retinoid for skin conditions such as acne has been linked to birth defects. As a precaution, pregnant women may want to choose a sunscreen without the ingredient retinol palmitate or retinyl palmitate.
Based in this info, EWG's concerns are based on animal data. The human data are only short term, so the effects in humans are unclear.
PP here. I meant to say the short term human data show no effect. The long term human effects are unclear.
