So how do you choose the right sunscreen? There are two categories of sunblock: physical blockers, which deflect sunlight and protect against both types, and chemical blockers, which absorb sunlight and vary in their protection. The former of the two is preferred, but tend to leave a white film on your skin, so you’re trading comfort/appearances for protection against skin cancer. Seems like fair trade off to me. For specific brand recommendations, check the Environmental Working Group’s list of best sunscreens. [...] [...] SPF is a misleading measure, since it only measures protection against UVB.
