Hawaii just passed a state law banning the sale of sunscreens containing the ingredients Oxybenzone and Octinoxate, making the state the first in the world to pass such a bill. The law goes into effect January 1, 2021 and is an effort to combat harmful effects from these ingredients on coral reef. Many of the inner reefs of Hawaii’s popular bays have died off due to years of heavy tourism.

In 2015, a study of coral reefs in Hawaii, the U.S. Virgin Islands and Israel found Oxybenzone and Octinoxate, two common sunscreen ingredients, damaged coral and affected the development of fish and other wildlife. It was estimated that approximately 14,000 tons of sunscreen lotions get washed off and end up in coral reefs around the world each year.


The sunscreen ingredients were concluded to cause damage and death in coral (“coral bleaching”) when they’re washed off the skin or disposed into wastewater treatment plants and then deposited into water. Coral reef protect coastlines from waves and also provide habitat for fish and other aquatic life. The report showed Oxybenzone is toxic to the juvenile form of corals and may also disrupt the symbiotic relationship between coral and algae, thus negatively affecting the health of the marine ecosystem.

The Hawaii Medical Association claim there is lack of peer-reviewed evidence that sunscreen is the cause of coral damage. There are other factors which may be contributing to coral reef death including global warming, overfishing, industrial pollution and runoff. There is also concern that banning these sunscreen ingredients could lead Hawaiian residents and tourists to use less of sunscreen and thus increase their risk of skin cancer. Skin cancer rates in Hawaii are 30% higher than the national average.

So- what sunscreen ingredients should you look for? If you’d like to avoid chemical sunscreen ingredients like Oxybenzone, then look for SPF blockers like Zinc oxide and Titanium dioxide (called “mineral sunscreen” ingredients). Also practice other sun-safe habits like staying in the shade when outdoors, wear big hats and sunglasses, stay indoors during peak sun hours, wear UV protective clothing. I also recommend avoiding aerosol sunscreens as these are more likely to leave residue and droplets on the beach and sand which can end up in the ocean (not to mention, the risk of inhalation with the aerosol sprays).

Also in development are sunscreens containing only natural and organic ingredients. These are likely not to have been subjected to rigorous testing and approval, so it is difficult to know how effective and how protective from harmful UV rays they truly are. Other major companies are likely going to develop and release sunscreen products that don’t contain Oxybenzone and Octinoxate.
