The Sunscreen Problem and how it Affects Corals in the Caribbean
In order to preserve the Corals and the marine life around it, we recommend using when possible, natural sunscreen alternatives that can effectively protect you from the sun's harmful UVA and UVB rays.
Sunscreen can indeed have a significant impact on coral reefs. It is now well-established that certain chemicals found in sunscreen and other personal care products can be harmful to coral ecosystems. These chemicals can enter the water when sunscreen washes off our skin while swimming or showering. Chemicals such as oxybenzone contaminate the water. These chemicals are absorbed by coral, and their nanoparticles can interfere with the coral's ability to reproduce and grow, leading eventually to coral bleaching.
To protect coral reefs while still protecting ourselves from the sun, consider using sunscreen without harmful chemicals: Look for sunscreens labeled as "reef-safe" or "reef-friendly" that are free from oxybenzone, benzophenone, and other harmful ingredients. Instead, opt for mineral-based sunscreens that use non-nano zinc oxide or titanium dioxide as the active ingredients.
In terms of SPF, the term "natural" typically denotes mineral sunscreens that contain naturally-derived minerals
Seek shade and cover up whenever possible. Wear protective clothing like hats, rash guards, and pants to minimize the amount of sunscreen needed. This not only protects your skin but also reduces the amount of sunscreen entering the water.
