Everything You Need to Know About Sunscreen

Turns out there’s more to sunscreen than you think—ingredients, SPF ratings, and application instructions matter when picking out your sun protection. We took our questions about sunscreen to Melissa Wilson, PA-C, MPAS, Melanoma Lead AIM at Melanoma's Ask an Expert and Lead Physician Assistant, Melanoma Program at UPMC Hillman Cancer Center and AIM at Melanoma's resident "Ask an Expert" and here's what she had to say. What are some common ingredients in sunscreen and how do they work? What’s the difference between UVA and UVB rays? What do different SPF ratings mean? How and when should I apply sunscreen? The information in this video is correct as of 1 July 2022.
