Dermatological and environmental…zone/benzophenone-3.

97% of people tested had oxybenzone in their urine, and the chemical shows up in waterways and fish worldwide. In humans, it's linked to allergic reactions and suspected of disrupting hormones; environmentally, it damages coral reefs and harms fish. The researchers question whether oxybenzone's sun protection actually justifies these health and environmental risks, especially since safer alternatives like zinc oxide exist.
