Okay, maybe it’s not just for men, but you can’t help but feel studly when you look at the labels for these bottles of 30 SPF sunscreen. And yes, it’s real; apparently Ferrell is pulling a Paul Newman and selling Completely Random Products for charity. In this case, the proceeds go to a scholarship fund for cancer survivors.
The difference in UVB protection between an SPF 100 and SPF 50 is marginal. Far from offering double the blockage, SPF 100 blocks 99 percent of UVB rays, while SPF 50 blocks 98 percent. (SPF 30, that old-timer, holds its own, deflecting 96.7 percent).
A recently issued rule from the FDA would overhaul and expand the agency’s fight against the sun’s radiation. The proposed regulation would require sunscreen makers to test for effectiveness against UVA rays, which unlike UVB rays, do not burn the skin; UVA instead gives us an attractive bronze that can cause cancer.
