Sunscreen over an SPF 30When you use an SPF 15, about 95 percent of UVA/UVB rays are blocked, which is pretty good, and with an SPF 30, closer to 100 percent of UV rays are shielded, says Lancer. So what's up with SPF 31-100 then? It's similar to speedometers that go up to 200 mph in a car, he says. You're never going to be able to go that fast -- well, without getting a serious speeding ticket anyway. So basically, SPFs over 30 are a bit superfluous. And all sunscreens must be reapplied after swimming or sweating anyway, so you should be fine with an SPF 15 or 30. See other sunscreen mistakes you might be making.
