Newsflash: Sunscreen isn’t akin to a hazmat suit. But the power to defend yourself optimally is literally in your hands.

The rules for sunscreen have changed yet again. Yes, you still have to apply it, and not just in the summer or when there are no clouds. But Health Canada says it can no longer be called “sunblock”—it’s not denim, so some UV is getting through—or “waterproof.” (“Sunscreen” and “water-resistant” are allowed.) This will spare us from a false sense of security.

New logos will indicate UVA protection, as SPF only measures UVB. UVA rays are insidious: You can’t see or feel them, and they penetrate deeply into the skin, causing evils such as loss of elasticity and wrinkling. We know this is not what you want to hear poolside, but shade and clothing are your best allies. “Sunscreen should be your last line of protection,” says Toronto dermatologist Dr. Sonya Cook. “And it’s more about compliance than a number.” If you don’t apply the proper amount—a teaspoon for your face, a golf ball for your body—and do it every two hours, you risk not being protected at all. Don’t say we didn’t warn you.
