SolRX™ was started with the belief that a healthy life includes a healthy amount of time spent outside. That love of the outdoors especially extends to our oceans and lakes. Our commitment to reef friendly products is in our DNA. All our products are 100% Oxybenzone free. Beyond that, our WATERBLOCK™ system stays in place until you release it with soap and water. So NO ingredients (not even zinc) will easily rinse off onto reefs. No other sunscreen can make that claim. We also proudly support Surfrider Foundation (surfrider.org), Sea Turtle Conservancy (conserveturtles.org) and other ocean related charities.
