A day at the beach cannot happen without putting on sunscreen — did you know, however, a sunscreen that is not reef-safe can potentially harm marine life? Many sunscreens have harmful chemicals in them that kill coral, add to ocean pollution, and harm marine ecosystems. When you select reef-safe sunscreen, you can protect your skin while protecting the planet, allowing you to make a sustainable beach getaway.
1. What is Reef-Safe Sunscreen?
Reef-safe sunscreens do not contain harmful chemicals like oxybenzone and octinoxate, known to harm coral and cause DNA damage in marine life. Reef-safe sunscreens use mineral-based ingredients like zinc oxide and titanium dioxide. Mineral-based sunscreens contain ingredients that sit on the upper surface of the skin and deflect UV rays instead of absorbing it, providing protection without harming the ocean.
2. Why It Matters
Coral reefs are vital to marine ecosystems - they provide shelter to 25% of the ocean's species and protect coastlines from erosion. Even the smallest measurement of harmful ingredients in sunscreen can kill coral. When swimmers wear chemical sunscreen, they wash off into the water, and that's how these ingredients accumulate in coral reef areas. Reef-safe sunscreen is good for the planet and for the ocean and guardians the conservation of the ocean when you can enjoy a day in the sun without leaving harmful chemicals behind in the ocean.
3. How to Pick a Reef-Safe Sunscreen
Look for sunscreens labeled “reef-safe,” “reef-friendly,” or “non-nano zinc oxide.” Avoid any sunscreen containing parabens, silicones, or synthetic fragrances — as these can irritate skin and potentially harm marine life. Get a broad-spectrum SPF of at least 30 to ensure protection from both UVA and UVB rays. If you're wondering is sun bum sunscreen safe, there are some mineral-based products that meet reef-safe designations — just double-check the ingredient information, just in case.
4. Application Tips for the Most Coverage
No matter how eco-friendly your sunscreen is, it is not going to work right if you're not applying it properly. Use about one ounce (a shot glass amount) when applying sunscreen for the body and reapply every two hours, especially if you've gone swimming or towel dried off. You can also prevent burning of your skin by wearing UPF rated swimwear, hats, and sunglasses to help protect against the harsh UV rays.
Closing Perspective
You can protect your skin while keeping the ocean protected, too. Choosing a reef-safe sunscreen is a simple and powerful way to help preserve marine ecosystems while also maintaining your skin health, radiance, and sun-safe fun on your next beach excursion.
