Sunscreen: Could It Be Toxic??
Summary
Host Wendy Zuckerman and producer Michelle Dang investigate whether sunscreen is toxic or causes vitamin D deficiency. They debunk myths about chemical ingredients like oxybenzone, explaining that while some absorb into the blood, they do not harm humans at typical doses. The episode also clarifies that sunscreen prevents skin cancer in lighter skin tones, though darker-skinned individuals may benefit more from vitamin D supplements than daily sunscreen for cancer prevention.
