Chemical pollution from sunscreen contributes to coral bleaching in our oceans. Made in collaboration with Stream2Sea using EcoSafe Zinc™, this 100% mineral-based broad-spectrum UVA/UVB sunscreen balm is scientifically formulated to be safe for both humans and coral reefs.
Already a favorite among divers, ocean conservationists, and the 4ocean crew, this powerfully effective formula is non-greasy, applies sheer, won’t burn your eyes, and is water resistant up to 80 minutes.
Made and packaged right here in Florida, our reef-safe sunscreen comes in an infinitely reusable and recyclable aluminum tin for sun protection that’s good for you, our coral reefs, and our planet.

“As a diver and Florida native, I have personally witnessed the decline of our reefs over the last 25 years. The scariest part is that decline is accelerating at a crazy pace. I do not believe that toxic sunscreens are the largest contributor to reef decline, but they absolutely DO contribute and it is such an easy problem to eliminate.Our reefs need every chance they can get to survive, and if we can easily eliminate one of the stressors, I believe it is our duty to do so.”

Wear it everywhere you need sun protection
Did you know that modern wastewater treatments don’t remove oxybenzone or other harmful chemical ingredients from water before it’s discharged?That’s why the sunscreen you choose matters whether you live 10 minutes from the beach or 10,000 miles.We believe ALL water deserves to be protected, so our sunscreen has been tested for biodegradability, aquatic toxicity, and coral reef safety in both fresh and saltwater environments.
