I just found this article online, check it out.
“The Skin Cancer Foundation does acknowledge that sunscreen alone is not enough. You need to wear protective clothing (pricey new fabrics such as Solumbra apparently block both UV-A and UV-B, but a wide hat and long, lightweight summer clothing should suffice), and spend more time in the shade. If you’re a beach lover, invest in a sun umbrella. But think twice before you slap on sunscreen. Some cement mixers destroy the roads we’re told they build. And some products may contribute to the cancer we’re told they prevent.”
