Why You Should Use Water-resistant Sunscreen When it comes to sun protection, there are a lot of options out there. But if you really want to make sure you’re protected from the sun’s harmful rays, you should use a water-resistant sunscreen. Water-resistant sunscreen is specifically designed to stay on your skin even when you’re swimming or sweating. It’s made with an active ingredient that forms a barrier on your skin to prevent water from washing away the sunscreen. While water-resistant sunscreen is more expensive than regular sunscreen, it’s worth the investment because it will keep you protected from the sun for longer. So, next time you’re at the store, be sure to pick up a bottle of water-resistant sunscreen!
