If you care about both your skin and the planet (especially the ocean!), you might be wondering: Is mineral sunscreen actually reef safe? With more travelers seeking eco-friendly skincare and legislation tightening around sunscreen ingredients, it’s crucial to know what you’re putting on your skin and what ends up in our oceans.
Let’s dive into what makes a sunscreen reef safe, why mineral SPF is the better choice, and how you can protect both your skin and coral reefs with clean, conscious products like Blume's Sunburst Mineral SPF 50.
What Does "Reef Safe" Even Mean?
"Reef safe" is more than a buzzword. It refers to sunscreen formulas that do not contain ingredients known to harm coral reefs, like oxybenzone and octinoxate. These chemicals have been linked to coral bleaching, DNA damage in marine organisms, and disruption of aquatic ecosystems.

In fact, Hawaii, Palau, and other destinations have banned sunscreens containing those ingredients due to their environmental impact.
Mineral vs. Chemical Sunscreens
So where does mineral sunscreen come in? Mineral sunscreens use natural minerals like zinc oxide and titanium dioxide as active ingredients, which sit on top of your skin and reflect UV rays. They offer broad-spectrum protection without absorbing into your bloodstream or disrupting marine life.

Mineral sunscreen is not only safer for coral reefs, it's also safer for your sensitive or acne-prone skin. Unlike some chemical formulas that can clog pores or trigger irritation, mineral sunscreens like Sunburst SPF 50 are non-comedogenic and lightweight.

Why Zinc Oxide is a Hero Ingredient
Zinc oxide is the MVP when it comes to reef-safe sun protection. It provides a physical barrier against UVA and UVB rays, works immediately upon application, and is generally recognized as safe by the FDA.
Unlike chemical UV filters, zinc oxide is non-nano in many reef-safe formulations. That means the particles are too large to be ingested by coral and other marine life, reducing the ecological footprint of your SPF.

The Environmental Impact of Chemical Sunscreens
According to a report by the National Park Service, an estimated 14,000 tons of sunscreen enter coral reef areas annually. Even small amounts of harmful ingredients like avobenzone, octocrylene, and homosalate can bleach coral and damage reef development.
That’s why switching to a reef-friendly SPF is more than just a personal choice. It's a step towards preserving biodiversity.
How to Tell If a Sunscreen is Truly Reef Safe
Look for sunscreens that:
-
Are labeled "reef safe" or "reef friendly"
-
Contain only non-nano zinc oxide or titanium dioxide
-
Are free of oxybenzone, octinoxate, avobenzone, and octocrylene
-
Avoid microplastics, parabens, and fragrance
