Using sunblock and sunscreen is important to protect your skin from the sun. They are the same thing even if they have different names. It’s better to avoid buying special ''reef safe'' sunscreens because global warming and ocean pollution are bigger threats to coral reefs. Sunscreens usually last for about three years if stored properly. No sunscreen is waterproof, so you need to reapply it every two hours. Higher SPF ratings like 50 and 100 are more effective and let you reapply less often. Remember to stay safe in the sun!
