Using expired or half-used sunscreen can increase the risk of sunburn; buying new sunscreen each season is recommended.
There are two types of sunscreen: chemical and mineral; mineral sunscreens are safer, eco-friendly, and better for coral reefs and marine life.

Common Mistake: Using Old Sunscreen
Using expired sunscreen or reusing half-used bottles can lead to degraded active ingredients and increased risk of sunburn and skin damage. Dermatologists recommend buying new sunscreen each season to ensure maximum protection.
Choosing the Right Sunscreen
There are two types of sunscreen: chemical and mineral. Chemical sunscreens absorb UV radiation, while mineral sunscreens physically block the sun. Both types have pros and cons, and the choice depends on personal preference. Mineral sunscreens, like those containing zinc oxide, are considered safer and may be better for those with sensitive skin. Additionally, mineral sunscreens are eco-friendly and better for coral reefs and marine life.
Applying Sunscreen Correctly
One common mistake is not applying enough sunscreen. The recommended amount is about an ounce and a half for the whole body and a teaspoon for the face. It's also important to reapply sunscreen every couple of hours and not rely on one application lasting all day. Additionally, using spray sunscreens can make proper coverage challenging, so it's essential to ensure all areas of the body are adequately covered.
Sunscreen: we should all be using it, but we might not all be using it the right way. In fact, the type of sunscreen you use may not be nearly as important as using it effectively. With the help of a few expert dermatologists, NPR science correspondent Allison Aubrey cues Scientist in Residence Regina G. Barber into six common mistakes to avoid when using sunscreen and how to stay safe in the sun this summer.
