[...] with bottles and tubes covered with claims, "it's really hard to make sense of what all the terminology means," says Roopal V. Kundu, M.D., an associate professor of dermatology at the Northwestern University Feinberg School of Medicine, who researches how people buy and use sunscreen.

Here, then, is the help you need: seven common terms and what they actually mean—and don't. The federal government requires sunscreen claims to be "truthful and not misleading." But only three of the main claims consumers see—"SPF," "broad-spectrum," and "water-resistant"—are strictly regulated by the [U.S.] government and therefore have agreed-upon definitions.

The article goes on to explain those terms as well as "sport," "dermatologist recommended," "natural," "mineral" and "reef safe."

    Your tan may kill you, even if you don't burn.

    Literally anything that increases the rate of cell division increases the rate of cancer.

    Melanoma rates doubled in the 20 years from 1986–2006 and are still on the rise.

    Interesting, so as more people wear sunscreen and avoid tans there is more melanoma:

    Slip-Slop-Slap was the iconic and internationally recognised sun protection campaign prominent in Australia and New Zealand during the 1980s. Launched by Cancer Council Victoria in 1981,[1] the Slip! Slop! Slap! campaign features a singing, dancing Sid Seagull encouraging people to reduce sun exposure and protect themselves against an increased risk of skin cancer.[2] Sid had Australians slipping on long-sleeved clothing, slopping on sunscreen and slapping on a hat.

      children and teens get exposed, then develop cancer years, or (more often) decades later, so any drop from campaigns in the last twenty years may not show for another twenty.

      As well, there may be diagnostic drift. https://articles.mercola.com/sites/articles/archive/2011/11/20/deadly-melanoma-not-due-vitamin-d-deficiency.aspx [mercola.com]

        So there is no evidence that sunscreen is preventing melanoma, only wild speculation. Further, melanoma rates keep increasing worldwide along with sunscreen use but no one has bothered to figure out whether it is due to sunscreen or not:

        For years, primary care providers have advised patients to use sunscreen as a means to reduce their risk of skin cancer, especially cutaneous malignant melanoma (CMM). However, between 1973 and 2003, the incidence of CMM increased by 81% and continues to increase at a rate of 3% per year.1 According to a 2006 US Environmental Protection Agency publication, “there is no evidence that sunscreens protect you from malignant melanoma.”2 A number of studies suggest that the use of sunscreen either does not significantly decrease the risk or may actually increase the risk of CMM.3–7

        So, as usual, the understanding is rudimentary but these health experts are advocating people buy some chemical to put on/in their body anyway.

          Actually, they recommend staying out of the sun and covering up in high UV periods, AND wearing suncream.
          They realise most people just won't stay under cover, so hats, long sleeves and suncream are the 'next best' options.

          Besides, everyone knows someone who has tanned all their life and not died of cancer, so it won't get you either, right?

            Whatever, its pretty obvious that trying to avoid all sun exposure leaves you vulnerable to tiny bursts of it and will increase any UV induced cancer. Also there is whatever vitamin D effect... These are the same organizations who triggered an obesity epidemic by recommending a high carb diet for decades right?
