It seems as if there is a new scare about sunscreens every other week - this time it's whether zinc oxide sunscreens become ineffective and toxic 2 hours after application. Ellie and I discuss why it's important to treat these sensationalist claims with skepticism. I also speak with Dr Mark Lebwohl who is a renowned dermatologist from Mt Sinai in New York City about patient advocacy groups in dermatology, new treatments for inflammatory skin diseases, and the importance of diversity in dermatology.
