Sunscreen: Could It Be Toxic??

27 de agosto de 2026 · 51 min

Notas do episódio

Sunscreen is supposed to protect us from dangerous stuff like cancer, but all over social media, people are saying that we’ve been getting it all wrong. We’re being told that our sunscreen is full of toxic chemicals, that wearing it could mess with our vitamin D levels — even that sunscreen itself actually increases our risk of skin cancer. So, what can the science tell us here? Should we toss our SPF-filled creams and sprays in the bin?? And could the answer here be different depending on your skin tone? We talk to researchers Dr. Brandon Adler, Prof. Rachel Neale, and Dr. Adewole Adamson to find out.
