Best Sunscreen for Coral Reefs – Top 5 Options for Your Next Dive!

Aside from their gears, divers also bring one staple: sunscreen. Although they are submerged in water, direct sunlight can still cause damage to the skin, especially on the face. But before you smother a bottleful of sunscreen before the plunge, have you checked if it’s reef safe? The best sunscreen for coral reefs will not just protect you from the UV rays, but it will also prevent coral damage due to synthetic chemicals.

What’s with reef-safe sunscreens? 

As you know, sunscreen products are made of various chemicals. The likes of octinoxate and oxybenzone are two of the sunscreen ingredients believed to worsen coral bleaching. Bleached corals aren’t technically dead, but it’s heavily damaged and will take decades to heal. 

With this, Hawaii became the first U.S. state to ban the use and sale of sunscreen containing the two mentioned chemicals. This law will take effect by 2021. 

Based on the data of the National Park Service, about 14,000 tons of sunscreen are dumped to coral reef each year. This is an accumulation of sunscreens used by tourists, locals, and divers.

Aside from octinoxate and oxybenzone, you should also avoid sunscreens with petrolatum or mineral oil as well as titanium dioxide. Mineral oil takes years to decompose while titanium dioxide doesn’t decompose at all. While these chemicals linger on seawater and coral reefs, it becomes a direct threat to marine life as well as waterfowl. 

Regardless if you’re diving in Hawaii or not, it’s worth switching to reef-safe sunscreens. Why wait for corals to get bleached before you make a move? A collective switch to reef-safe sunscreens ensures that the divers of the future will still see magnificent underwater life. 

Also, as a responsible diver, it’s your responsibility to preserve and protect the ocean. You can do this with the simple idea of using a reef-safe sunscreen. 


The thing about high SPF sunscreen

According to Dr. Craig Downs of Haereticus Environmental Laboratory, using a high SPF sunscreen isn’t always a good thing. It’s packed with more chemicals, and thus will have more impact in the ocean. Dr. Downs said that high SPF sunscreen’s benefits are quite overstated.

With this, Dr. Downs recommends that you stick with SPF 30 reef-safe sunscreens that have passed FDA’s testing and guidelines. An FDA-approved SPF 30 will protect you against UV rays for 90 minutes then you’ll have to re-apply it thereafter. Most dives will last for about 30 to 90 minutes, which is the same duration of protection of an SPF 30 sunscreen.

With this, you can do the ocean a favor by limiting the SPF of your sunscreens while observing the ingredients. 

Aside from using sunscreen, you can also protect yourself from UV rays by wearing enough sunwear. When diving, you can slip on a wetsuit with a hood. This way, you can limit the exposure of your skin to harmful rays. 


Buying Guide for the Best Sunscreen for Coral Reefs

The best sunscreen for coral reefs is the one that protects you from harmful rays without endangering marine life. We recommend that you take the following points into account: 

-Check the ingredients!

The first thing you have to check when purchasing a reef-safe sunscreen is its ingredients. Like what’s mentioned above, you must avoid two ingredients: octinoxate and oxybenzone. These two chemicals are known to contribute to coral bleaching.

Make sure that your sunscreen is non-nano, which are larger and will not be absorbed by the corals. Also, it must be paraben-free and free of harsh chemicals that may trigger skin irritations. This brings us to another point: your personal sensitivities and allergies. Make sure that there are no chemicals in the sunscreen that will trigger your irritations.

-Select the right SPF

Aside from the ingredients, the next thing you have to check is the SPF level of the sunscreen. Basically, the higher the SPF, the longer the protection would be. However, as the SPF level increases, more chemicals are added to the sunscreen. 

For most dives, we recommend an SPF 30 sunscreen. This can protect you for up to 90 minutes, which is the duration of most dives. If you will be exposed to sunlight beyond 90 minutes, feel free to re-apply the product. 

-Look for a water-resistant formula

Since you’re diving, you must look for a water-proof formula. That way, the sunscreen will not be washed away once you plunged in the water. Still, you have to be put it on at least 15 to 20 minutes before the dive to give the skin enough time to absorb the formula. 

-Try to avoid excessive chemicals

As much as possible, avoid sunscreens with an unending list of chemicals that are hard to pronounce. The more chemicals there are in the sunscreen, the higher its impact will be on the ocean. If possible, look for an all-natural sunscreen. 

-Ditch spray sunscreens 

If you want the best sunscreen for coral reefs, forget about spray versions. About 30% of spray formulas don’t get into your skin. Worse, you get to inhale it, and if the formula has nanoparticles, it can cause damages to your lungs, especially on repetitive exposure.

Frequently Asked Questions

Q: How will I know if my sunscreen is coral-safe?

A: The determiner whether your sunscreen is coral-safe or not is the ingredients. If the sunscreen has octinoxate and/or oxybenzone, it will be dangerous to the corals. These sunscreens are banned in Hawaii and will cause coral bleaching. 

Q: Why is oxybenzone harmful to corals?

A: Oxybenzone is an active ingredient that converts UV rays into harmless heat once it reaches the skin. Octinoxate has the same effect. However, when these two chemicals reach the two corals, they will reduce the coral’s defenses against harsh elements. This will cause DNA damage to the corals which will stymie their growth. 

Q: Is the Banana Boat sunscreen coral-safe?

A: No. Lab tests showed that Banana Boat, along with brands like Coppertone and Tropicana, produces sunscreens with chemicals that damage reefs. You should consider getting reef-safe sunscreens like the five options we reviewed above. 

Q: What are the side effects of oxybenzone to the skin?

A: Although rare, the chemical oxybenzone on sunscreens can cause rashes, skin irritations, acne breakouts, and inflammation of the hair follicles. Though this doesn’t happen all the time, oxybenzone’s effects on the corals are much worse and prevalent. 

Q: Do I need to use sunscreen when diving?

A: If the location of the dive has intense sunlight, it’s worth using a reef-safe sunscreen. This will protect your skin from UV rays that cause skin cancer. Just make sure that the ingredients of the sunscreen will not be damaging to corals.
