Before heading to the beach, most people make sure to pack a bottle of sunscreen. After all, the ultraviolet rays can be seriously damaging and no one wants to get skin cancer. But it turns out some ingredients in hundreds of common sunscreens don’t work as well as advertised, according to a new report released by the Environmental Working Group (EWG). Additionally, 73 percent of 880 sunscreens that were tested contain “worrisome” ingredients people may not want to slather on their skin.

Authors of the report, which was released on Tuesday, examined the SPF protection, chemical ingredients and overall safety and effectiveness of numerous sunscreens, moisturizers, and lip balms. Then, they compiled a list of the best- and worst-rated products to help consumers make the best – and healthiest – choices when preparing to have fun in the sun.

Sonya Lunder, a senior analyst with the environmental advocacy group and lead scientist of the 2017 Sunscreens Guide, said of the findings, “Sunscreens are really mismarketed, and as a result, people who depend on them think they are far more powerful than they really are.”

According to dermatologist Dr. Dawn Davis, who did not participate in the report and works at the Mayo Clinic, the SPF is a ratio of how long a person without sunscreen can be in the sun without becoming red. In his own words, “if you’re standing on the equator at high noon and it would usually take your skin one minute without sunscreen to become red and irritated, SPF 15 means you can stand in that same sun exposure for 15 minutes.”

Most sunscreen brands offer products with high SPF, sometimes even over 100. Thought to be beneficial, they are actually misleading, says Lunder. “People who buy high-SPF products are more likely to get burned because they assume they’re getting better and longer-lasting protection,” she said. It is for this reason that she supports the American Academy of Dermatology’s recommendation to choose a sunscreen that is at least SPF 30 (which would block 97% of UVB rays) and suggests one reapply it every few hours. SPF protection can also vary, depending on its age, how it has been stored and lab tests find that SPF levels can vary wildly.

There is also something to be said about the questionable ingredients in certain sunscreens. While most chemicals in the product create a barrier to prevent damage from UV rays, other chemicals create damaging effects. Two ingredients, in particular, oxybenzone and retinyl palmitate, consumers should avoid. According to Lunder, oxybenzone “is a hormone disruptor that mimics body hormones and affects reproductive tract and other hormones.” And Retinyl palmitate, a form of vitamin A, has been linked to the development of skin tumors under direct UV light. More research needs to be conducted on the latter, but authors of the report advise consumers to avoid sunscreens that contain both ingredients.

All in all, the report recommends sunscreen products that are safe and offer adequate sun protection. The EWG says outdoor enthusiasts should look for three things: an SPF between 30 and 50 to protect from UVB rays, zinc oxide and titanium oxide to ward off UVA rays, and no oxybenzone and retinyl palmitate.
