You know to look for a sunscreen with SPF 30 (at least), that's broad spectrum (aka protects from UVA and UVB rays), and is water-resistant...but do you know if it's reef-safe?

A 2008 European study found that approximately 14,000 tons of sunscreen end up in oceans each year. The highest concentrations were found near coral reefs that are most popular with tourists. This means the sunscreen you put on before surfing, kayaking, or swimming in the ocean can wash off and remain in the ocean, causing serious damage to coral reefs and marine life.

How, exactly, are sunscreens messing with the ocean?

A 2015 study in the journal Archives of Environmental Contamination and Toxicology found that the popular sunscreen ingredient oxybenzone is directly linked to coral bleaching, the top cause of coral death worldwide.

Here’s the thing: Oxybenzone and octinoxate are super-common ingredients found in more than 3,500 sun protection products, according to NPR. They also pop up in many moisturizers, primers, and foundations that contain SPF. So it's crucial to look for a reef-friendly option.

What makes a sunscreen reef-safe?

If you're looking for a chemical sunscreen (sunscreens that sink into skin and work by absorbing UV rays and converting them to heat), any version that does not contain oxybenzone or octinoxate are considered safe for ocean use.

As for mineral (aka physical) sunblocks, which are powered by the minerals zinc oxide and titanium dioxide and sit on top of your skin to deflect UV rays, look for key words like "non-nano" or "reef friendly" on the label, which means the particles aren't small enough to be absorbed by, and harm, marine life.

The 11 Best Reef-Safe Sunscreens:

1. Coola Mineral Face Organic Matte Tint Sunscreen Lotion SPF 30

This slightly tinted formula blends in easily without leaving behind white streaks—a hard feat for mineral sunscreens. It also contains rosehip oil—a natural form of vitamin C—to help brighten and smooth your skin's tone and texture.

2. Bare Republic Mineral Mousse SPF 30

The whipped texture of this 100 percent zinc sunscreen makes slathering it on a little less of a chore. The macadamia nut oil and natural coconut and vanilla scent will also keep you coming back for more—and not because you're supposed to be reapplying every two hours.
