Why is it Important to Use Reef-Safe Sunscreens?


Zinc is a natural alternative to chemical skincare. Seventy-five percent of sunscreens are toxic and contain harmful chemicals such as oxybenzone, octinoxate, and homosalate. These chemicals’ effects are harmful to humans and marine wildlife. Hawaii has recently banned the sale of sunscreens containing oxybenzone and octinoxate that researchers worldwide have determined are harmful to aquatic ecosystems.

A 2016 study by the national Oceanic and Atmospheric Administration (NOAA) and other institutions found that baby coral exposed to oxybenzone and octinoxate exhibited signs of distress, including coral bleaching. Coral bleaching is a condition that leaves coral vulnerable to infection and prevents the coral from getting the nutrients it needs to survive, as well as causing DNA damage and abnormalities in its growth and skeleton. In addition, other studies have found these chemical ingredients to be harmful to other marine life as well, such as fish, sea urchins, and shrimp.

Our sunblocks at 4 Ring Protection do not contain any of these chemicals. We are committed to helping preserve our marine life and ecosystem. You can wear this sunscreen with the assurance that you are not harming our delicate coral reef habitats.
