When it comes to sunscreen, we all know it’s a must-have for skin protection. But did you know that some could be harming our oceans and coral reefs? Let’s separate fact from fiction and uncover the truth about its environmental impact.
Myth 1: Any sunscreen is better than none.
Fact: While it’s is essential for protecting your skin from harmful UV rays, not all sunscreens are created equal. Many contain chemicals like oxybenzone and octinoxate, which have been shown to damage marine life. The key is choosing one that protects both your skin and the environment.
Myth 2: Chemicals wash off in small amounts, so they can’t really harm the ocean.
Fact: Even tiny amounts of harmful chemicals can have devastating effects on marine ecosystems. Studies have found that as little as one drop of oxybenzone in an Olympic-sized pool can cause coral bleaching and DNA damage in corals. Since millions of people swim in the ocean every year, these chemicals accumulate, threatening the health of marine life.
Myth 3: Coral bleaching is caused only by climate change.
Fact: Climate change is the primary driver of coral bleaching, but these chemicals play a role as well. Research has shown that oxybenzone and other UV filters contribute to coral stress, making them more susceptible to bleaching and disease. Choosing reef-safe option is one way to reduce our impact on these fragile ecosystems.
Myth 4: If it says “reef-safe,” it must be environmentally friendly.
Fact: The term “reef-safe” isn’t regulated, so some products labelled as such may still contain harmful ingredients. To truly protect marine life, look for ones with non-nano zinc oxide or titanium dioxide as active ingredients and avoid oxybenzone, octinoxate, and other toxic chemicals.
Myth 5: Mineral sunscreens don’t work as well as chemical ones.
Fact: Mineral sunscreens (made with zinc oxide and titanium dioxide) provide excellent broad-spectrum protection against UVA and UVB rays. In fact, they often work immediately upon application, unlike chemical sunscreens, which require about 20 minutes to become effective.
Myth 6: It’s the only way to protect yourself from UV damage.
Fact: While it is crucial, it’s not the only way to stay safe in the sun. Wearing protective clothing, hats, and sunglasses, and seeking shade during peak sun hours (10 AM to 4 PM) are additional strategies to minimize UV exposure.
How to Choose an Eco-Friendly Sunscreen
So how can we protect both your skin and the environment? Let’s consider these tips when selecting a sunscreen:
- Look for mineral-based sunscreens with non-nano zinc oxide or titanium dioxide.
- Avoid oxybenzone, octinoxate, and other harmful chemicals that contribute to coral bleaching.
- Check for third-party certifications like the Environmental Working Group (EWG) rating or “Reef-Safe” labels from reputable organizations.
- Use lotion-based sunscreens instead of sprays, which can release harmful particles into the air and ocean.
Protecting Yourself and the Planet
A balanced approach to sun safety involves making mindful choices. Here’s how you can protect both your skin and the environment: Wear UPF-rated clothing and wide-brim hats. Choose eco-friendly, mineral-based sunscreens. Rinse off in a shower before entering natural water bodies to reduce sunscreen runoff. Support brands that prioritize sustainability and reef-safe formulations.
