The sun is shining, the waves are crashing, and you’re ready to hit the beach. But before you do, there’s something you need to know: your sunscreen could be harming the coral reefs. But have you ever wondered about the question, “What is reef safe sunscreen?”.
Well, coral reefs are an important part of the ecosystems that support a wide variety of marine life. But they’re also fragile, and they’re being threatened by a number of factors, including climate change, pollution, and overfishing.
One of the biggest threats to coral reefs is sunscreen. Some sunscreen ingredients, such as oxybenzone and octinoxate, can break down into chemicals that are harmful to coral. These chemicals can damage coral DNA, interfere with their reproduction, and make them more susceptible to disease.
The good news is that there are many reef-safe sunscreens available. These sunscreens use ingredients that are less harmful to coral, such as zinc oxide and titanium dioxide.
So, if you’re planning on spending time at the beach, be sure to choose a reef-safe sunscreen. It’s a small change that can make a big difference in the health of our coral reefs.
Now, let’s dig deeper.
What Is Reef Safe Sunscreen?
Coral reefs are some of the most important ecosystems on Earth, providing food and shelter for millions of marine organisms. However, coral reefs are under threat from a number of factors, including pollution, climate change, and overfishing. One of the biggest threats to coral reefs is sunscreen.
Sunscreens that contain certain chemicals, such as oxybenzone and octinoxate, can damage coral reefs. These chemicals can disrupt the coral’s DNA, causing it to bleach and die. In fact, a study by the National Oceanic and Atmospheric Administration (NOAA) found that oxybenzone can kill coral at concentrations as low as 6 parts per trillion.
To protect coral reefs, it is important to use reef-safe sunscreen. Reef-safe sunscreen does not contain oxybenzone or octinoxate, and it is also biodegradable, meaning that it breaks down in the environment and does not harm marine life.
There are a number of reef-safe sunscreens available on the market. These sunscreens typically contain zinc oxide or titanium dioxide, which are mineral ingredients that block UV rays. Reef-safe sunscreens are just as effective as sunscreens that contain oxybenzone or octinoxate, and they are also safe for your skin.

Why is It Important to Have Reef-Safe Sunscreen?
Reef-safe sunscreen is important because it helps protect coral reefs from the harmful effects of sunscreen chemicals. Coral reefs are a vital part of our planet’s underwater ecosystem, and they are facing a number of threats, including climate change, pollution, and overfishing.
Sunscreen chemicals are one of the more recent threats to coral reefs, and they can cause coral bleaching, which is a process that causes the coral to lose its color and eventually die.
The two most common sunscreen chemicals that are harmful to coral reefs are oxybenzone and octinoxate. These chemicals are absorbed by coral and can disrupt their DNA, which can lead to bleaching. They can also interfere with the coral’s ability to reproduce.
When people wear sunscreen and then go swimming, the sunscreen can wash off and enter the ocean. This can happen even if you use a sunscreen that is labeled as “waterproof” or “sweatproof.” Over time, the accumulation of sunscreen chemicals in the ocean can have a significant impact on coral reefs.
There are a number of reef-safe sunscreens available that do not contain oxybenzone or octinoxate. These sunscreens are just as effective at protecting your skin from the sun’s harmful rays, and they are also safe for coral reefs.
If you are planning to visit a beach or other area with coral reefs, it is important to use reef-safe sunscreen. You can also help to protect coral reefs by avoiding sunscreen altogether and covering up with clothing, a hat, and sunglasses.
Tips for Choosing a Sunscreen That is Safe for Coral Reefs
Here are some tips for choosing a sunscreen that is safe for coral reefs.
- Look for sunscreens that do not contain oxybenzone or octinoxate. These two ingredients are the most common sunscreen chemicals that are harmful to coral reefs.
- Choose sunscreens that use zinc oxide or titanium dioxide as the active ingredients. These minerals are considered to be reef-safe and are just as effective at protecting your skin from the sun’s harmful rays.
- Avoid sunscreens that are labeled as “nano.” Nanoparticles are smaller than 100 nanometers in diameter and can be more harmful to coral reefs than larger particles.
- Look for sunscreens that are labeled as “reef-safe” or “reef-friendly.” This is not a regulated term, but it is a good starting point.
- Check the Environmental Working Group’s (EWG) sunscreen guide. The EWG sunscreen guide rates sunscreens based on their ingredients and potential environmental impact.
Why Does Sunscreen Affect Reefs?
Sunscreen can affect reefs because some of the chemicals in sunscreen can be harmful to coral. These chemicals can enter the ocean through wastewater effluent and directly from swimmers wearing sunscreens. Once in the ocean, they can accumulate in coral tissues and cause a variety of problems, including.
- Bleaching: Coral bleaching occurs when the algae that live in the coral’s tissues are expelled, causing the coral to lose its color. This can be caused by a number of factors, including pollution, high water temperatures, and exposure to sunscreen chemicals.
- DNA damage: Sunscreen chemicals can damage the DNA of coral, making them more vulnerable to disease and other stressors.
- Deformities: Sunscreen chemicals can cause deformities in coral larvae and young coral, making them less likely to survive.
- Death: In some cases, exposure to sunscreen chemicals can kill coral.
The most common sunscreen chemicals that are harmful to coral are oxybenzone and octinoxate. These chemicals are found in many sunscreens, so it’s important to choose a sunscreen that’s free of them if you are concerned about the health of coral reefs.
