Reef-safe and Biodegradable Sunscreen: What You Should Know

Read the full story at Treehugger.

Biodegradable or reef-safe sunscreen refers to a specific sunblock formula that degrades naturally and doesn’t contain chemicals that could be harmful to the environment, specifically coral reefs. 

In one study, researchers found that just a small amount of sunscreen containing the ingredient oxybenzone could be enough to break down coral, causing it to lose its nutrients, bleach, and often die. Reef-safe or biodegradable sunscreens don’t contain these chemicals and are safer for the marine environment. 

While scientists disagree about the exact impact of chemical sunscreen on reefs, biodegradable and reef-safe sunscreen is popular among consumers who wish to reduce their overall impact on marine life.
