What Sunscreens are Reef-Safe?
There are many sunscreens that are marketed as being “reef-safe” or “coral reef friendly.” However, there is no definitive answer as to whether or not any sunscreen is completely safe for reefs. Some sunscreens contain ingredients that can be harmful to marine life, while others may not be as harmful but could still potentially have an impact.
The best way to ensure that your sunscreen is not harming reefs is to choose a mineral-based sunscreen that does not contain any of the following ingredients: oxybenzone, octinoxate, 4-methylbenzylidene camphor, parabens, triclosan, and nano-particles. These ingredients have all been shown to be harmful to coral reefs in some way. Additionally, it is important to remember that even if a sunscreen is reef-safe, you should still take measures to avoid getting it into the water (such as applying it before swimming and making sure you don’t rub it off into the water).
