An emerging concern among ocean scientists, stewards and beachgoers is the impact that certain chemical sunscreens are having on the marine environment. This has led to bans on the sale and use of chemical sunscreens in states and island communities such as Hawaii, Key West and Aruba, and a proposed federal ban in all U.S. National Marine Sanctuaries containing coral reefs. There has also been a surge in the production of "reef friendly" sunscreens — but what does that actually mean, and how safe are these alternative sunscreens to the marine environment?


As an alternative to sunscreen made with toxic chemicals, mineral-based sunscreen is often used as a "reef friendly" option. While mineral-based sunscreens are better for the marine environment than sunscreens with toxic chemicals, such as oxybenzone, octinoxate and octocrylene, there are still risks associated with their use. The most common active ingredients in mineral sunscreens are zinc oxide and titanium dioxide.

How Do I Know If a Sunscreen Is "Reef Friendly"?

Unfortunately the term "reef friendly" is not regulated, so you can't always trust products with this description. It's important to actually check the "active ingredients" label on the back of your sunscreen or personal care product to ensure that reef-harming chemicals are not included. The size of minerals can also have an impact. Be sure to use micro-sized (or non-nano) mineral sunscreens to avoid nanoparticles, as these smaller particles can be toxic in high concentrations.

It's also advised to stick with lotions and avoid spray or misting sunscreens, especially those that contain titanium dioxide as it can be harmful to your health if inhaled. Finally, it's always good to use products that cut back on single use plastic packaging, either by using containers that are reusable, have high recycled content or are made out of biodegradable plant-based materials like cardboard.

Check the Label

Make sure your sunscreen does not contain the following harmful substances on the HEL list:

  • Oxybenzone
  • Octinoxate
  • Octocrylene
  • 4-methylbenzylidene camphor
  • PABA
  • Parabens
  • Triclosan
  • Any nanoparticles or "nano-sized" zinc or titanium (if it doesn't explicitly say "micro-sized" or "non-nano" and it can rub in, it's probably nano-sized)
  • Any form of microplastic, such as "exfoliating beads"

How Else Can I Protect Myself From the Sun, and Our Coasts From Harmful, Chemical Sunscreen?

Use Sun Management

Even mineral-based sunscreens can negatively impact fish and coral reefs at high concentrations. The best thing we can do is limit products when recreating in high use areas. Effective sun protection methods include a balance of:

  • Avoiding sun exposure during peak sun hours (10 am – 2 pm)
  • Covering up- Wear hats and clothing (can be UPF or even just regular)
  • Using a more reef friendly sunscreen on exposed areas

Spread the Word and Advocate for Bans on Reef Harming Sunscreens

In addition to changing our actions and purchasing decisions to protect the marine environment, it's also important to spread awareness about the issue to friends, family and community members. At the local level, ensure that your town's stores are offering "reef friendly" sunscreen products, and encourage them to stop the sale of harmful products (feel free to share this handout with your community).

You can also advocate for local legislation that bans the sale and use of toxic sunscreens. For instance, in 2018, Hawaii passed the first ever statewide ban on oxybenzone and octinoxate sunscreens, soon after, island nations including Palau, Bonaire and Aruba followed suite. Due to widespread community support, the Florida Keys were also able to pass an oxybenzone and octinoxate sunscreen ban in Key West, but chemical companies have been working tirelessly to try and revoke this important legislation through the use of statewide preemption — learn more here.

At the federal level, you can ask your federal representatives to support the first federal bill to ban oxybenzone and octinoxate sunscreens in National Marine Sanctuaries with coral reefs! National Marine Sanctuaries are home to some of the ocean's most biologically diverse and culturally significant marine areas, and we need to ensure that these critical areas are protected from harmful chemicals, in addition to other damaging practices like oil and gas extraction.

Please call your House representatives in Washington DC and ask them to support HR 1834 — Defending Our National Marine Sanctuaries from Damaging Chemicals Act of 2019, and ask your Senate representative to support or sponsor a similar bill.

Colette Pichon Battle gave a December 2019 TEDWomen Talk on the stark realities of climate change displacement, and people took notice. The video racked up a million views in about two weeks. The attorney, founder, and executive director of the Gulf Coast Center for Law & Policy (GCCLP) advocates for climate justice in communities of color. Confronted with evidence showing how her own South Louisiana coastal home of Bayou Liberty will be lost to flooding in coming years, the 2019 Obama Fellow dedicates herself to helping others still reeling from the impacts of Katrina face the heavy toll that climate change has taken—and will take—on their lives and homelands. Her work focuses on strengthening multiracial coalitions, advocating for federal, state, and local disaster mitigation measures, and redirecting resources toward Black communities across the Gulf South.

"These are not just wildfires, they are climate fires," Jay Inslee, Governor of Washington State, said as he stood amid the charred remains of the town of Malden west of Seattle earlier this month. "This is not an act of God," he added. "This has happened because we have changed the climate of the state of Washington in dramatic ways."
