Sunscreen—the best way to tell summer was finally here as a kid. Now, it’s the most important step in our skincare routines! If you’re not already wearing sunscreen each and every day, this is your sign so keep reading to learn how to get started. And if you are, kudos! Let’s make sure all your bases are covered.
SPF Explained
SPF stands for “sun protection factor,” and it’s how we measure the protection from the sun’s UVB rays. For example, SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97%, and SPF 50 blocks 98%. Experts recommend staying between 30 and 50 SPF—it’s sufficient protection without feeling a false sense of complete sun protection with an option over 50.
You’ll want to make sure your sunscreen is “broad-spectrum,” meaning it protects from both UVA and UVB rays. An easy way to distinguish the two is UVA(ging) and UVB(urning). Both rays have overlapping effects (i.e. both can cause burns and premature aging), but UVA rays are mostly responsible for fine lines and dark spots, while UVB rays play the most significant role in producing skin cancers and sunburns.
Everyone under the sun should wear sunscreen, no matter your skin tone. Generally speaking, you’ll need ½ a teaspoon of sunscreen for your face and neck, then one ounce (enough to fill a shot glass!) for your entire body. Since sunscreens naturally break down over time, we recommend reapplying every two hours, and even more frequently if you’re swimming or sweating. Don’t forget—you need to apply your sunscreen 30 minutes prior to sun exposure!
