Summer’s finally here and you’re likely itching to spend some fun-filled time in the sun. But not so fast: The first stop on your summer to-do list is to protect your skin from those blazing rays. Protecting your skin is serious business, so it’s not a surprise if you feel lost when it comes to picking out sunscreen. What do SPF numbers mean? Does water resistant mean waterproof? What’s the difference between mineral or synthetic sunscreen? We have the answers to your questions right here!
First off, know the facts about sunscreen.
There are three key things to know about sunscreen and what to look for on the label:
- Broad spectrum: This means your sunscreen shields against both UVA rays (which hit the deepest layer of your skin) and UVB rays (which target the top layers of your skin and cause you to burn), providing you with maximum protection.
- Sun Protection Factor or SPF: This is the key number on the label of your sunscreen container. SPF indicates the ability of the sunscreen to protect your skin from rays that cause sunburn. According to the Skin Cancer Foundation, SPF 15 protects your skin from 93 percent of UVB rays, SPF 30 shields up to 97 percent, and SPF 50 blocks 98 percent.
- Water-resistance: Even if you’re not going swimming, summer heat can cause you to sweat, making it hard for sunscreen to stay put. Water-resistant sunscreen products will better protect your skin. But remember, no sunscreen is completely waterproof or sweat-proof. If your skin gets wet, you need to reapply.
When to apply and how much sunscreen is enough?
Whichever sunscreen you pick, it’ll only protect your skin if you use it correctly. You should use one full ounce, or the amount that would fill the palm of your hand to cover your entire body. Here are the numbers you should know in regard to applying and reapplying sunscreen:
- 30 minutes: Apply sunscreen at least 30 minutes before heading outside.
- 2 hours: This is the length of time your sunscreen application is effective according to the FDA.
Mineral or Synthetic sunscreen?
Active ingredients in sunscreens come in two forms, mineral and synthetic filters. Each uses a different mechanism for protecting skin and maintaining stability in sunlight.
- Synthetic sunscreen: Ingredients typically include a combination of two to six of the following: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate. These ingredients can cause irritation to those with sensitive skin.
- Mineral sunscreen: Ingredients include zinc oxide and/or titanium dioxide and have almost no risk of irritating skin.
