Don't Drink Your Sunscreen

In this episode, Ariel breaks down the science and history of sunscreen, covering UVA/UVB/UVC radiation, how SPF actually works, mineral vs. chemical filters, and the newly FDA-approved ingredient bemotrizinol — the first new sunscreen active ingredient approved in the U.S. since the 1990s. The group chat then myth-busts the biggest sunscreen claims making the rounds online: hormone disruption, "sunscreen causes cancer," reef damage, skin irritation, and the viral watermelon-smoothie trend claiming lycopene can protect you from the sun. Olivia presents some good news: A Lancet study showing HPV and measles vaccines prevent more deaths per dose than any other vaccine funded through Gavi, giving global health leaders a clearer way to prioritize funding amid tighter budgets. Also, stick around to hear Mattie's takes on Meta's Muse Image AI feature and the backlash that got it pulled.
