But benzene isn't necessary for sunscreen production. ![]() Valisure's findings are concerning because there is no safe amount of benzene in any product, according to the FDA, which refers to it as a Class 1 Solvent. Leukemia (cancer of blood-forming organs), anemia (a decrease in red blood cells), excessive bleeding and decreased ovary size have all been linked to long-term benzene exposure, according to information from the CDC and Department of Health and Human Services. Benzene, an industrial chemical normally found in crude oil and cigarette smoke that can also be used in manufacturing plastic and pesticides, is a known human carcinogen that can cause harm with long-term exposure, which is exposure for more than one year, according to the Centers for Disease Control and Prevention. (We also use a reference sunscreen with known performance to ensure the accuracy of the testing.) About a day later, a trained technician examines the areas for redness.The findings are detailed in Valisure's May 24 petition to the Food and Drug Administration to recall the product lots that contain dangerous amounts of benzene. Afterward, smaller sections of that area are exposed to five to six intensities of UV light from a sun simulator for a set time based on how quickly the panelist’s skin burns without protection. Then they soak in a tub of water for 40 or 80 minutes, depending on the product’s water-resistance claim. To check SPF, a standard amount of each sunscreen is applied to a 2x3-inch rectangle on each panelist’s back. We also do a different test to determine UVA protection, which we think gives more helpful results. “We use three samples, preferably with different lot numbers, of each product.” For SPF-a measure of how well a product protects against UVB rays-we test the sunscreens on fewer people than the FDA’s protocol calls for, and we test only after water immersion because if a product holds up on wet skin, it should hold up on dry skin. “We buy the sunscreens for our tests off the shelf, the way consumers would,” says Susan Booth, who oversees our sunscreen testing. CR members have access to our full sunscreen ratings. Below are some of the top-performing sunscreens in our tests, listed in alphabetical order within their category. So whatever your issues with sunscreen-whether you think it’s greasy or gloppy, you don’t use enough of it, or you’re just overwhelmed by the number of different products to choose from-our advice and ratings can help. Our sensory specialists also objectively evaluate the scent and feel of each sunscreen and provide a description so you can choose a product that appeals to you. (Protection against UVB is represented by a sunscreen’s SPF.) Both types contribute to skin cancer risk. UVA rays are primarily responsible for aging, while UVB rays are the ones that mostly cause sunburn. We’ve tested dozens of sprays and lotions in the lab to determine how well they will protect your skin against radiation from ultraviolet A and B rays from the sun. ![]() But we’ve discovered major differences even among products made by the same brands, and our tests have found that sometimes the protection offered by a sunscreen doesn’t match the SPF listed on the label. And Consumer Reports testing has found that you don’t have to pay top dollar to find one that works. There’s an elixir that can keep your skin from looking old before its time and protect you against the most common type of cancer-it’s called sunscreen. ![]()
