Best Reef Safe Sunscreen – Top 10 Reviewed

Looking to enjoy scuba diving, snorkeling, or any other water-related activity without harming your skin or the delicate coral reefs? Then you need the best reef-safe sunscreen to provide you with reliable protection against UV rays while not being toxic to reefs.

How do you find the best sunscreen that is reef safe?

Today, we’ll be helping you accomplish your mission as we present you with a list of the top 10 reef-safe sunscreens your money can buy. So let’s not waste any time and get started!

Why do you need sunscreen when scuba diving or snorkeling?

It’s a common misconception for people to think that going scuba diving or snorkeling means you won’t be needing sunscreen. However, you should keep in mind that you won’t be underwater all the time. The trip to get there is going to expose you to harmful UV rays so you want to be ready.

Besides developing unwanted tan lines, exposure to sun rays can lead to painful sunburns. While most cases are 1st degree, prolonged or repeated exposure to UV rays without proper protection can end up causing skin cancer.

This is why you should never underestimate the intensity of the sun’s rays, even when you’re not particularly aiming to sunbathe!

Using Reef Safe Sunscreen when Snorkeling or Diving

How does sunscreen harm reefs?

When you apply sunscreen before scuba diving or snorkeling, some of the product is very likely to wash off your skin and into the surrounding water when you’re actually in or underwater.

Sunscreens typically contain chemicals such as oxybenzone and octinoxate that can harm marine life. When such compounds accumulate in coral reefs, they can induce bleaching, cause DNA damage, deform baby coral, and even kill reefs.

What sunscreens are bad for coral reefs?

Sunscreens come in 2 main types: chemical and mineral. Mineral sunscreens create a barrier to block sun rays physically, while chemical sunscreens absorb UV rays. The mineral type is generally considered reef-safe, but chemical sunscreens are far from being safe.

Why? Because most, if not all, chemical sunscreens contain oxybenzone that has been proven to cause coral bleaching.

What ingredients in sunscreen are bad for reefs?

According to the National Oceanic and Atmospheric Administration, the list of ingredients in sunscreens that can harm coral reefs include:

  • Oxybenzone
  • Benzophenone
  • PABA (Para-aminobenzoic acid)
  • Nano zinc oxide
  • Nano titanium dioxide

What sunscreens are banned in Hawaii?

Sunscreens containing oxybenzone and octinoxate are banned in Hawaii. This will go into full effect starting January 1, 2021, at which point the sale or distribution of such sunscreens will be prohibited.

What are the best Reef Safe and Friendly Sunscreens and Brands?

After learning the possibly devastating effects of regular sunscreens on coral reefs, you’re probably asking: What is the best reef-safe sunscreen? What brand makes the best reef-friendly sunscreen products? Well, here’s a list of the top 10 reef-safe sunscreens available on the market to answer your question!
