Yes, our sunscreen is designed to be environmentally friendly and therefore does not contain any organic UV filters known or suspected to affect aquatic life. They also do not contain any of the organic UV filters that are suspected to be harmful to corals and are therefore "reef safe". Our sunscreens contain both titanium dioxide and zinc oxide, the latter in particular being associated with environmental concerns. Zinc is a substance that occurs naturally in the environment and is essential for the normal functioning of all cells and organisms. Therefore, only higher levels of zinc can be toxic. Our sunscreen contains a small amount of zinc, resulting in a limited spread and addition of zinc to the environment. Overall, we have made the assessment that the low amount has a very small impact on the natural amount already present in our environment and that the positive benefits of zinc oxide in sunscreen products outweigh the risks of its use and that our product does not pose an environmental problem.
