Staying protected from harmful UV rays is paramount. However, when protecting your skin, also consider the environmental impact of your sunscreen. The “Toxic 3 Os” — oxybenzone, octinoxate and octocrylene — are prohibited in the United States Virgin Islands. Choose a mineral sunscreen containing zinc oxide and titanium dioxide which are deemed safe and effective by the FDA. In addition, don't forget to wear a hat and put on a rashguard if you plan to stay in the water for a long time.
