Sunscreens are carcinogenic! I live in the desert. I swim a lot in the summer and I haven't used sunscreen for years because I've known this. I've never had skin cancer even though my skin is very fair. However, I do have friends and family who repeatedly suffer from skin cancer and they continue to lather on sunscreen every time they are in the sun. They still think their skin cancer is coming from the sun so they use their sunscreen even more! 🙄
