I want a sunscreen that is safe for coral reefs and does not use oxybenzone.

To protect coral reefs, you need a mineral (physical) sunscreen that relies on non-nano zinc oxide and/or titanium dioxide as its active ingredients. True reef-safe formulas completely exclude harmful chemical filters like oxybenzone, octinoxate, octisalate, and avobenzone, as well as parabens and microplastics.

What to Look For on the Label:

• Active Ingredients: Only Zinc Oxide and/or Titanium Dioxide.
• Particle Size: Must state "Non-Nano" (particles larger than 100 nanometers), meaning they are too large for coral to ingest and won't harm marine life.
• Avoid: Oxybenzone, octinoxate, homosalate, and parabens.

Top Reef-Safe & Oxybenzone-Free Sunscreen Brands:

Stream2Sea Reef-Safe Sunscreen / 4ocean Balm — Rigorously tested and proven safe for both aquatic life and human skin, utilizing 100% non-nano zinc oxide.

Thinksport / Thinkbaby SPF 50+ — A pioneer in clean mineral protection, highly rated by the Environmental Working Group (EWG) for safety and non-toxicity.

Blue Lizard Sensitive Mineral Sunscreen — Mineral-based, fragrance-free, and designed specifically to omit oxybenzone and octinoxate.

All Good Mineral Sunscreen Butter / Lotion — Certified organic, highly water-resistant, and built with non-nano zinc oxide for active ocean use.

Raw Elements Face and Body SPF 30 — Plastic-free tin options and a heavy-duty, natural non-nano zinc formula popular with surfers and divers.

Would you prefer a recommendation tailored to a specific use case, such as face vs. body, daily wear under makeup , or heavy water-resistance for swimming and surfing?

Yes. If your priority is avoiding oxybenzone and minimizing potential impact on coral reefs, I’d favor a mineral sunscreen with zinc oxide and/or titanium dioxide. The EPA specifically recommends considering titanium dioxide or zinc oxide instead of oxybenzone near coral reefs.www.epa.gov

One caveat: “reef safe” isn’t a scientifically standardized claim, and research on sunscreen ingredients and coral ecosystems is still evolving.www.epa.gov

What I'd look for on the label

For the most conservative reef-conscious choice, choose SPF 30–50+ with zinc oxide as the active ingredient, and avoid oxybenzone (benzophenone-3) and preferably octinoxate as well. Also, don't rely solely on the phrase “reef safe”—check the actual active ingredients.

And when you're snorkeling/diving, a rash guard + hat + shade is even better for the reef because it reduces the amount of sunscreen entering the water. The EPA recommends this approach too.www.epa.gov

If you tell me whether you want it for your face, body, or both—and whether you prefer a lotion that rubs in clear—I can narrow this to the 2–3 best options.

To ensure a sunscreen is truly safe for coral reefs and entirely free of oxybenzone, your best option is to look for mineral (physical) sunscreens that use non-nano zinc oxide and/or titanium dioxide as their only active ingredients.

Chemical sunscreens—even those labeled "reef-friendly" that swap oxybenzone for other chemical filters like avobenzone or octisalate—can still sometimes stress marine life. Non-nano mineral particles sit on top of the skin rather than absorbing or washing into the water in ways that harm delicate coral ecosystems.

Top-rated, truly reef-safe options that skip oxybenzone completely include:

1. • Badger Adventure Mineral Sunscreen Cream SPF 50 - Made with just a few simple, organic ingredients and high non-nano zinc oxide content; available on platforms like REI.
2. • Organic Reef-Safe Sunscreen Broad Spectrum SPF 40 - A lightweight, plant-based mineral formula featuring uncoated non-nano zinc oxide; options can be found via Truly Free.
3. • Thinksport Body Sunscreen SPF 50+ - Highly rated by the Environmental Working Group (EWG) for safety and uses non-nano zinc oxide.
4. • Blue Lizard Sensitive Mineral Sunscreen SPF 30+ - Widely accessible, dermatologist-recommended, and uses zinc oxide and titanium dioxide.

Would you prefer a sunscreen that is fragrance-free / for sensitive skin , or one optimized for heavy water sports and sweating ? Let me know and I can narrow down the best specific pick for your trip.

Best bet: choose a mineral, non-nano zinc oxide and/or titanium dioxide sunscreen, ideally SPF 30–50 and water-resistant. “Reef-safe” isn’t a regulated label, so check the ingredients.www.aad.org

If you're traveling to Hawaii, I'd stick with mineral-only formulas because Maui and Hawaiʻi County have stricter mineral-only rules.www.mauicounty.gov

Yes. For the most reef-conscious choice, I’d look for a mineral sunscreen whose only active ingredients are zinc oxide and/or titanium dioxide, rather than relying on a “reef-safe” label. The National Park Service specifically recommends this approach and notes that “reef-safe” isn’t a regulated term.www.nps.gov

• Badger Reef-Safe Mineral SPF 50 — zinc oxide, non-nano; a particularly straightforward option for swimming and outdoor activities.

One important caveat: “reef safe” doesn't mean a sunscreen has been proven completely harmless to coral. The scientific evidence is still developing, and the American Academy of Dermatology notes that the term itself isn't FDA-defined. www.aad.org NOAA likewise recommends mineral sunscreen as a better environmental option because chemical UV filters can affect aquatic organisms.oceanservice.noaa.gov

My practical checklist: SPF 30+, broad-spectrum, water-resistant if swimming, and ideally non-nano zinc oxide as the only active ingredient. Also consider a UPF rash guard and shade, which reduces the amount of sunscreen washing into the water.www.aad.org

If you tell me whether you want face, body, or both and your approximate budget, I can narrow this to 2–3 choices with the least white cast.

Yes. If your priority is avoiding oxybenzone and minimizing potential coral impact, I’d look for a 100% mineral sunscreen, ideally using non-nano zinc oxide as the active ingredient.

One important caveat: “reef-safe” isn't a scientifically regulated sunscreen category, so the label alone isn't enough. dlnr.hawaii.govdlnr.hawaii.gov Also, avoiding oxybenzone doesn't mean a product has been proven completely harmless to coral. For the most conservative approach, use non-nano zinc oxide, choose water-resistant formulas, and supplement sunscreen with a rash guard, hat, and shade. Hawaiʻi's guidance specifically recommends mineral filters and protective clothing.dlnr.hawaii.gov

My simplest pick: Badger Reef-Safe Mineral SPF 50 if you're buying primarily for beach/snorkeling use; Blue Lizard Sensitive SPF 50 if you want something more everyday-friendly.

If you tell me whether you want face, body, or both and your budget (e.g. under $20), I can narrow it down to 2–3 choices.
