Is sunscreen good for coral reefs?

Sunscreen is an essential part of our sun protection routine, but have you ever wondered about its impact on the environment, particularly coral reefs? In recent years, concerns have been raised about certain sunscreen ingredients harming coral reefs.

In this blog post, we'll explore the relationship between sunscreen and coral reefs, discuss the potential risks, and offer tips on choosing reef-friendly sunscreens. Let's dive in!


What are 'Reef Safe' Sunscreens?

Understanding the Impact: Certain chemical ingredients commonly found in sunscreens, such as oxybenzone and octinoxate, have been shown to have harmful effects on coral reefs. These ingredients can cause coral bleaching, disrupt coral reproduction, and contribute to coral reef decline. It's estimated that around 14,000 tons of sunscreen enter coral reefs each year, primarily through swimmers, snorkelers, and divers.


How To Find 'Reef Safe' Sunscreens?

The good news is that there are reef-friendly sunscreen options available that help minimize the impact on coral reefs. Here are some tips for choosing sunscreen that is safe for both your skin and the environment:


Look for "Reef-Friendly" or "Reef-Safe" Labels

Opt for sunscreens that are specifically labeled as "reef-friendly" or "reef-safe." These products are formulated without oxybenzone and octinoxate, two of the most concerning ingredients for coral reefs.


Choose Mineral-Based Sunscreens

Mineral-based sunscreens, containing zinc oxide or titanium dioxide, are generally considered safe for coral reefs. These ingredients work by creating a physical barrier on the skin to reflect and scatter UV rays, rather than being absorbed into the skin like chemical sunscreens


Avoid Nanoparticles

If you opt for mineral-based sunscreens, choose those with non-nano zinc oxide or titanium dioxide particles. Non-nano particles are larger and less likely to be absorbed by corals, reducing potential harm


Check for Biodegradable Formulations

Consider sunscreens labeled as "biodegradable." These formulations are designed to break down more easily in the environment, minimizing their impact on aquatic life, including coral reefs.


Wear Protective Clothing

Another way to reduce your reliance on sunscreen and its potential impact is to wear protective clothing, such as hats, long-sleeved shirts, and UV-protective swimwear. This can help decrease the amount of sunscreen needed on your skin.


While sunscreen is crucial for protecting our skin from the harmful effects of UV rays, it's important to be mindful of its potential impact on coral reefs. By choosing reef-friendly sunscreens that are free of harmful ingredients and following responsible sun protection practices, we can enjoy the sun while minimizing harm to the environment. Remember, making informed choices about sunscreen is not only beneficial for our own well-being but also contributes to the preservation of our precious coral reefs.


Note: Remember to always follow local regulations and guidelines when using sunscreen in marine environments to ensure the protection of both your skin and the delicate ecosystems.
