Best Biodegradable Sunscreen

Choosing the best sunscreen will keep you and your family safe.

But did you know that your choice also impacts the environment?

70% of sunscreens on the U.S. market contain harsh chemicals, such as oxybenzone and octinoxate. These chemicals can damage or kill coral reefs.

Some popular vacation destinations, such as Cozumel, Mexico, have banned non-biodegradable sunscreens through federal regulations.

Here is everything you need to know about reef-safe sunscreen and our picks for the best biodegradable sunscreen.

How to Choose The Best Biodegradable Sunscreen 

The Best Biodegradable Sunscreen

Avoid Harsh Chemicals That Contribute to Coral Bleaching Such as Oxybenzone and Octinoxate

A lot of sunscreens contain chemicals such as oxybenzone and octinoxate. Sunscreen manufacturers include these chemicals because they are effective in blocking UV rays. However, studies have shown that they contribute to coral bleaching.

Coral bleaching is when algae leaves the coral's tissue due to pollution. The algae is the coral's main source of food. Without it, the coral gets sick and turns white.  

A well-known study in 2015 found that 14,000 tons of sunscreen enter the ocean and impact coral reefs every year. 

The harmful chemicals in sunscreen can still reach the ocean even if you aren't at the beach. When you shower, all the sunscreen on your skin rinses off and goes down the drain, eventually reaching our rivers and oceans. You can read more about it here

Hawaii and Key West, Florida approved legislation to ban sunscreens containing oxybenzone and octinoxate.

Carefully Review the Ingredients List

There aren’t any standards that sunscreen must meet to call itself “reef-safe”. The FDA hasn’t set definitions or limits on this hazard.  

If you aren’t careful, you can wind up paying more for sunscreen that says “biodegradable” or “reef-safe” when it is just marketing jargon.

Consumers should look at the ingredients list when purchasing sunscreen.

Try to avoid the chemicals listed below, as they can be harmful to coral reefs.

Chemicals in some sunscreens that can harm marine life include: Oxybenzone, Benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylidene camphor, 3-Benzylidene camphor, nano-Titanium dioxide, nano-Zinc oxide, Octinoxate, Octocrylene

Look For Chemical-Free or Mineral Sunscreen 

Some sunscreen brands use mineral blockers like zinc oxide and titanium dioxide. These ingredients block UV rays and won't harm the environment.

Furthermore, dermatologists say that chemical-free or mineral-based sunscreen is better for people with sensitive skin.

Frequently Asked Questions 

What about sunscreen for everyday use?

The best sunscreen that we know of for everyday use is SuperGoop!

It is weightless, invisible, oil-free, and scent-free!

It will protect you from harmful UV rays and is 100% reef-friendly! It is oxybenzone- & octinoxate-free and has clean, powerful ingredients like soothing frankincense & hydrating meadowfoam seed that nourish & protect your skin.

How do I know if my sunscreen is biodegradable? 

The best way to tell is by looking at the ingredients list. It shouldn’t contain oxybenzone, octinoxate, PABA, or methylbenzylidene camphor. Try to find sunscreen that uses natural or organic ingredients. You can also look at the labels on the packaging.

How does sunscreen hurt the environment?

Sunscreen rinses off our skin while in the water or after showering. It enters the ecosystem and acts like an oil or pollutant, covering coral reefs and essentially suffocating them.


Why are coral reefs important? Why is coral bleaching a problem? 

Coral reefs are important to our environment and economy. They protect coastlines from storms and erosion, house fish and other wildlife, and support our local economy through tourism. Additionally, coral reefs are important in the development of new medicines to treat cancer, arthritis, and other diseases.

Where can I buy biodegradable sunscreen?

We have found a lot of eco-friendly sunscreen brands on Amazon. None of the major sunscreen brands, such as Coppertone, are reef-safe. So, finding biodegradable sunscreen in your local store can be difficult. We like buying from brands that don’t use harmful ingredients and are active members of the Safe Sunscreen Council.

What if I have a sunscreen allergy? 

Ecofriendly sunscreen is likely a better option for people with sunscreen allergies. Dermatologists recommend using mineral-based sunscreen because it contains fewer chemicals that irritate your screen.

What is mineral-based sunscreen? 

Mineral-based sunscreen uses natural ingredients to form a physical shield between your skin and the sun’s UV rays. Look for products that say “zinc oxide” or “titanium dioxide” on the label.

Is biodegradable sunscreen as effective as normal sunscreen?

Yes, it is just as effective. Biodegradable sunscreen brands offer tons of SPF options (anywhere from SPF 15 – SPF 50 or more).

Will it rub in well?

Yes, it will.  Mineral-based sunscreens used to leave a “chalky cast” for people with darker skin tones, while chemical-based sunscreens did not. However, advancements have improved the texture and appearance of mineral-based sunscreen to the point where it is easier for people to use.
