Sunscreen can be a smokescreen. Sunscreen is unlikely to stop you from being sunburned, or to reduce your risk of developing skin cancer. That’s because most people don’t apply it properly, and stay in the sun too long.
The solution? Slather on sunscreen daily and reapply it often, especially if you’ve been in the water. How much? At least enough to fill a shot glass.
