Whether you live on the beach or in a landlocked city, all water eventually makes its way to the ocean, which is why it’s so important to use reef-safe sunscreen. Traditional sunscreens can be toxic both to your body and to our important ocean environments, but there are plenty of safe options available.

At its most basic, reef-safe sunscreen is sunscreen that only uses mineral-based UV-blocking ingredients. However, there’s no regulation on using the term “reef-safe,” so it’s important to thoroughly vet the ingredients of any product you’re considering purchasing.

To save you some time and effort, we’ve done the research for you, and in this article, we’ll break down the six best reef-safe sunscreens on the market today.

Why Switch to Reef-Safe Sunscreen?

Some places, like Hawaii, have banned many reef-harming sunscreens, but most Americans still have the choice to stick with traditional sunblocks or go the ocean-friendly route. Why switch to reef-safe sunscreen? There are a number of reasons, including:

  • According to National Geographic, there are as many as 82,000 kinds of chemicals from personal care products (including sunscreen) in the ocean, and in 2015 alone, around 14,000 tons of sunscreen ended up on coral reefs globally.
  • Even if you aren’t near the ocean, when you shower after applying sunscreen, much of it goes down the drain, entering the wastewater stream and eventually ending up in the sea.
  • Ingredients found in commercially made sunscreens such as oxybenzone, octinoxate, nano titanium dioxide and nano zinc oxide are toxic not only for reefs, but also for sea urchins, fish, marine mammals and other ocean creatures.
  • Oxybenzone can be absorbed by humans and has even shown up in urine and breast milk.
