Is Sunscreen Safe — And Does It Work?

Sunscreen is often discussed as either essential or suspicious, but the evidence-informed picture is more balanced. This episode looks at sunscreen use for sun protection, skin cancer prevention, vitamin D, and ingredient safety without turning the topic into an all-or-nothing debate.

Dr. Tara Moroz explores how public-health guidance frames sunscreen, why real-world sunscreen use matters, and how concerns about vitamin D and ingredient absorption can be misunderstood online. The episode also separates uncertainty from alarm, showing why ongoing safety review does not automatically mean proven harm.
