The term "coral reef safe" implies that it is safe for the entire reef, but how does one know this? Stream2Sea is the ONLY reef friendly mineral sunscreen that is tested and proven safe to fishes and coral larvae. We don’t like plastic either! That is why our tubes are made from sugarcane resins, our 32 oz bottles are made from recycled milk jugs, and our baggies are made with biodegradable and recyclable PLA film. Partnering and contributing to 1% for the Planet, the Coral Restoration Foundation, Reef Check, NAUI's Green Diver Initiative and many other eco-conscious non-profits is our way of giving back.
