In this article, we’ll delve into the world of sunscreens and explore which ones are not reef-safe, and what you can do to make a positive change.
Introduction to Reef-Safe Sunscreens
Coral reefs are some of the most diverse and intricate ecosystems on the planet, providing a home for a vast array of marine life. Unfortunately, these delicate ecosystems are facing numerous threats, including climate change, pollution, and the detrimental effects of certain chemicals found in sunscreens. Chemicals such as oxybenzone and octinoxate have been shown to contribute to coral bleaching, damage to coral DNA, and even the death of coral reefs. This has led to a growing demand for reef-safe sunscreens that utilize alternative active ingredients.
Understanding the Harmful Chemicals
To grasp the concept of reef-safe sunscreens, it’s crucial to understand the chemicals that are causing harm to coral reefs. Oxybenzone and octinoxate are two of the most common culprits, found in many chemical sunscreens. These chemicals can:
- Cause coral bleaching, which occurs when the coral expels its algal symbionts, turning white and often leading to the coral’s death
- Damage coral DNA, making it difficult for coral to recover from stress or adapt to changing environmental conditions
- Interfere with coral reproduction, leading to a decline in coral populations
Breakdown of Oxybenzone and Octinoxate
Oxybenzone and octinoxate are both chemical active ingredients that work by absorbing UV radiation, preventing it from penetrating the skin. However, when these chemicals are washed off into the ocean, they can have devastating effects on coral reefs. Oxybenzone, in particular, has been shown to be toxic to coral larvae, making it difficult for new coral to grow and develop.
Sunscreen Ingredients to Avoid
So, which sunscreens are not reef-safe? The answer lies in the ingredients. Here are some common chemical active ingredients that are known to harm coral reefs:
| Chemical | Effects on Coral Reefs |
|---|---|
| Oxybenzone | Causes coral bleaching, damages coral DNA, and interferes with coral reproduction |
| Octinoxate | Contributes to coral bleaching and damages coral DNA |
| Avobenzone | Less toxic than oxybenzone and octinoxate, but still may contribute to coral stress |
Reef-Safe Alternatives
Fortunately, there are many reef-safe sunscreens available on the market. These sunscreens utilize mineral active ingredients such as zinc oxide and titanium dioxide, which work by physically blocking UV radiation. These ingredients are non-toxic to coral reefs and provide excellent protection against UV radiation.
Benefits of Mineral Sunscreens
Mineral sunscreens have several benefits, including:
- Providing broad-spectrum protection against UVA and UVB radiation

What is the main concern with sunscreen and coral reefs?
The main concern with sunscreen and coral reefs is the presence of certain chemicals in sunscreen that can harm coral reefs. These chemicals, such as oxybenzone and octinoxate, have been shown to cause coral bleaching, damage coral DNA, and even kill coral polyps. When sunscreen is applied to the skin and then washed off in the ocean, these chemicals can enter the water and come into contact with coral reefs, causing harm to these delicate ecosystems. Additionally, these chemicals can also affect other marine life, such as fish and sea urchins, and can even contaminate the food chain.
The impact of sunscreen on coral reefs is a significant concern, as coral reefs are some of the most diverse and fragile ecosystems on the planet. Coral reefs provide habitat for a vast array of marine life, protect shorelines from erosion, and support commercial fisheries. However, coral reefs are already under threat from climate change, overfishing, and pollution, and the added impact of sunscreen chemicals can push these ecosystems over the edge. As a result, many organizations and governments are calling for a ban on the use of oxybenzone and octinoxate in sunscreens, and for the development of more reef-friendly sunscreen alternatives.
Which sunscreen ingredients are harmful to coral reefs?
The two main sunscreen ingredients that have been identified as harmful to coral reefs are oxybenzone and octinoxate. These chemicals are commonly used in sunscreen to absorb and scatter UV radiation, but they have been shown to have devastating effects on coral reefs. Oxybenzone, in particular, has been found to cause coral bleaching, which is when the coral expels its algal symbionts and turns white, often leading to the death of the coral. Octinoxate has also been shown to cause damage to coral DNA, which can lead to abnormal growth patterns and increased susceptibility to disease.
Both oxybenzone and octinoxate are commonly used in chemical sunscreens, which are the most popular type of sunscreen on the market. However, there are alternative sunscreen ingredients, such as zinc oxide and titanium dioxide, which are considered to be reef-friendly. These mineral active ingredients work by sitting on the surface of the skin and physically blocking UV radiation, rather than being absorbed into the skin like chemical active ingredients. As a result, they are less likely to be washed off into the ocean and come into contact with coral reefs.
How much sunscreen ends up in the ocean?
It’s estimated that up to 14,000 tons of sunscreen lotion are washed into the oceans each year, with a significant portion of this ending up on coral reefs. This can happen in a number of ways, including when people swim or shower off after applying sunscreen, or when sunscreen is washed off into the ocean through storm drains or sewage systems. Additionally, many popular tourist destinations, such as Hawaii and the Caribbean, have coral reefs located close to shore, which can increase the amount of sunscreen that ends up in the ocean.
The amount of sunscreen that ends up in the ocean is a concern, as even small amounts of oxybenzone and octinoxate can cause harm to coral reefs. In fact, studies have shown that concentrations of oxybenzone as low as 62 parts per trillion can cause coral bleaching, which is equivalent to a single drop of oxybenzone in 6.5 Olympic-sized swimming pools. As a result, it’s essential to take steps to minimize the amount of sunscreen that ends up in the ocean, such as using reef-friendly sunscreens, applying sunscreen in moderation, and washing off after swimming or showering.
What are some reef-friendly sunscreen alternatives?
There are several reef-friendly sunscreen alternatives available on the market, which use mineral active ingredients such as zinc oxide and titanium dioxide instead of oxybenzone and octinoxate. These sunscreens work by sitting on the surface of the skin and physically blocking UV radiation, rather than being absorbed into the skin like chemical active ingredients. As a result, they are less likely to be washed off into the ocean and come into contact with coral reefs. Some popular reef-friendly sunscreens include Badger, Blue Lizard, and Goddess Garden, which offer a range of products that are safe for use on coral reefs.
When shopping for a reef-friendly sunscreen, it’s essential to read the ingredient label carefully and look for sunscreens that use zinc oxide or titanium dioxide as the active ingredient.
