Why Reef-safe is failing us.

Summary

There is no globally recognised definition of "reef-safe."

The SunSafe® Reef Standard was developed to provide a transparent framework and higher standards for reporting criteria used for assessing marine-focused sunscreen criteria, helping consumers make informed choices for people and the planet, above and below the surface.

 

Case Study Report Analysis: 

Few sunscreen claims create more confusion than "reef-safe."

Over the past decade, research has raised concerns about the potential impact of certain sunscreen ingredients, including homosalate, oxybenzone, octinoxate and octocrylene, on coral reefs and marine ecosystems. In response, destinations such as Hawaii, Palau and Thailand have introduced restrictions on selected UV filters to help protect sensitive environments.

Despite widespread use of the term, there is still no globally recognised definition of "reef-safe." Different brands, retailers and jurisdictions apply different criteria, making it difficult for consumers to compare products with confidence.


Why it Matters:

Government reports and scientific reviews from around the world have identified concerns about the environmental impact of some sunscreen ingredients. With an estimated 4,000–14,000 tonnes of sunscreen entering coral reef areas annually, researchers have raised questions about the effects of certain UV filters on coral reefs, marine life and broader aquatic ecosystems.

SunSafe® Says

❌🪸 Reef-safe is not a globally regulated sunscreen claim.

 

The Reef SunSafe® is a report we use to assess sunscreen products against marine-focused criteria, helping consumers make more informed choices above and below the surface.

⚠️ Consider:

  • No sunscreen has been proven harmless in every marine environment
  • Reef-safe is not a regulated global definition
  • Formula, packaging, wash-off and user behaviour all matter
