With summer just around the corner, everyone is gearing up for outdoor adventures and stocking up on their favorite sunscreens! Not to mention, more and more of us are beginning to use sunscreen in our daily routines. 

Unfortunately, certain sunscreen ingredients can have serious negative consequences both for marine life and human health. 

But don’t be discouraged — if you know which ingredients to avoid, you can easily choose sunscreen products that protect both you and coral reefs! When making your next sunscreen purchase, avoid getting burned (besides from the sun) by ingredients that are harmful to you and the planet. 

Quick note upfront: This article is in no way intended to discourage people from using non-reef safe sunscreens to reduce their risk of skin cancer.

Why choose "reef safe" sunscreen?

Sunscreen, like other personal care products, eventually makes its way into our oceans. This can happen either directly (via swimming, surfing, diving, etc.) or indirectly when we wash sunscreen off our bodies. 

Coral bleaching

Coral bleaching can occur through pollution exposure to common (and less than ideal) sunscreen ingredients. Below are some fast facts about sunscreen and coral bleaching:

Hormone disruption for humans & marine life

Some sunscreen ingredients (described later) are absorbed by the body. Many are potential or known hormone disruptors which can ultimately lead to: 

  • Damaged reproductive systems
  • Decreased fertility
  • Birth defects
  • Stunted growth

What sunscreen is considered "reef safe?"

Chemical sunscreens without these ingredients

Chemical, or organic, sunscreens are made with active ingredients that essentially transform UV rays into heat that dissipates from your skin and prevents sun damage. 

This list of ingredients to avoid is based on known or potentially harmful ingredients to human health and marine life. 

Chemical Ingredients to Avoid

  1. Homosalate 
  2. Phthalates 
  3. Triclosan
  4. Avobenzone
  5. 3-benzylidene camphor 
  6. Oxybenzone (Benzophenone-3) 
  7. Octinoxate 
  8. Octocrylene 
  9. Enzacamene (4 methylbenzylidene camphor)
  10. PABA (Aminobenzoic Acid)

Physical or mineral sunscreen (no nano-particles)

Physical (or mineral) sunscreen is different from chemical sunscreen in that it sits on top of the skin to prevent UV damage. The most common physical sunscreen ingredients you’ll see are zinc oxide and titanium dioxide. 

However, the ideal “reef safe” physical sunscreens are ones made without nano-particles. This means the particle size (of zinc oxide or titanium dioxide) is large enough to avoid the risk of those particles being absorbed into the bloodstream. While research on this topic is ongoing, there is evidence that suggests nano-particles in large doses can have negative health impacts

Physical Ingredients to Avoid

Future reef safe sunscreen ingredients

Recent research points to algae extracts as a potential UV blocker that could be used in sunscreen formulations in the future. However, the FDA has to approve SPF ingredients before they can officially be used as sunscreen ingredients and as you might imagine, this is a very slow process. 

However, non-U.S. brands like Australian Gold are already beginning to include algae in their sunscreen formulations.  

Top 16 "reef safe" sunscreen brands to look for

The sunscreen brands listed here are are all physical (or mineral) formulations. Currently, there aren’t many chemical options out there that exclude known or potentially harmful ingredients. However, if any become available, I’ll make sure to include them in future articles!
