About this episode

The episode explores the complexities of sunscreen effectiveness, including new ingredients and the relationship between sunscreen use and skin color.

Sunscreen may seem simple: slather it on, stay protected. But the science is more complicated than the label suggests. Why is it so hard to stay safe in the sun? On The Sunday Story, we dig into the surprisingly high-tech world of sunscreen and the questions swirling around it. Justine Paradis of New Hampshire Public Radio breaks down the new ingredients, dispels SPF myths, and points to updated guidance around sunscreen use and how it relates to skin color.
