5 derms on their favorite reef-safe SPFs

Finding a good everyday sunscreen is one thing, but it’s worth switching things up when you hit the beach. In order to protect marine environments, the best SPF for the beach tends to be what’s known as “reef safe”: It doesn’t contain ingredients known to do additional damage to coral reefs. 

‘Reef-safe’ is an unregulated term, but generally refers to sunscreens free of oxybenzone and octinoxate, which are linked to coral damage,” says Ursula Diaz, cofounder of Honor MD Skincare and the Dr. John Diaz Med Spa in Beverly Hills. 

How to protect yourself from sun while swimming

If you’re venturing out into the water, the best way to protect yourself from the sun is to wear a long-sleeve shirt, rash guard, or wet suit, and only apply sunscreen to the neck, face, and the back of your hands. According to the Divers Alert Network, the largest scuba diving safety association, this strategy reduces sunscreen loads in the water by 90 percent.  

What to look for in a reef-safe sunscreen

For typical days at the beach, there are two ingredients to steer clear of on your SPF’s ingredient label: oxybenzone and octinoxate.

“I generally recommend any 100% mineral, non-nano zinc oxide sunscreen that avoids oxybenzone and octinoxate,” says dermatologist Dr. Naana Boakye, who dispenses skin advice to more than 61,000 followers on Instagram. “These ingredients are better for both the skin and the environment, especially for patients who are ocean enthusiasts or eco-conscious.” 

FYI, You don’t necessarily need an SPF over SPF 50 to get adequate sun protection. “Properly applied SPF 50 sunscreen blocks 98 percent of UVB rays; SPF 100 blocks 99 percent,” according to the Environmental Working Group. “When used correctly, sunscreen with SPF values between 30 and 50 offers adequate sunburn protection, even for people most sensitive to sunburn.”

FAQ

Reef-safe sunscreen refers to sunscreens that are made without certain UV filters that have been linked to coral reef damage. No SPF is totally impact-free, but these products typically avoid ingredients like oxybenzone and octinoxate; instead, they use mineral UV filters or alternative chemical filters considered less harmful to marine ecosystems.

Most reef-safe sunscreens avoid:

  • Oxybenzone
  • Octinoxate
  • Octocrylene
  • Homosalate

These ingredients have been associated with coral bleaching and harm to marine life. Always check the SPF’s ingredient lists since“reef-safe” isn’t a regulated term.

Mineral sunscreens are generally considered the most reef-safe option. Instead of chemicals, they use zinc oxide and/or titanium dioxide as active ingredients, which sit on the skin and reflect UV rays. Non-nano mineral formulas are often preferred, since they’re less likely to be absorbed by marine organisms.

Yes, some destinations require reef-safe sunscreen by law. Places like Hawaii, parts of Mexico, and certain island nations ban sunscreens containing oxybenzone and octinoxate to protect coral reefs. Be sure to check your destination’s laws before you leave for your next beach vacation. 

Reef-safe sunscreen can provide the same level of UV protection as conventional sunscreen when it is broad-spectrum and rated SPF 30 or higher. Be sure to reapply after two hours or after going in the water, since that’s a huge part of staying protected in the sun. 

Some reef-safe sunscreens, especially mineral formulas, can sometimes leave a white cast since the product sits directly on top of the skin. However, many newer products use micronized minerals, tinted formulas, or lightweight lotions to improve how they blend in and show up on different skin tones.

Reef-safe sunscreen is a good choice for anyone hitting the beach or who has sensitive skin (the ingredients in these formulas are often also reef-friendly). Think: 

  • Ocean swimmers and snorkelers
  • Travelers visiting reef-protected areas
  • People with sensitive or acne-prone skin
