Why using reef safe sunscreen is important?

Anyone swimming or snorkeling in the tropical ocean near coral should consider a coral reef safe sunscreen. It is not a mystery that sunscreen that washes off your body when swimming may affect aquatic life.  Some commonly used chemical sunscreen ingredients cause coral bleaching and may be affecting coral reefs. In fact near 10% of the world’s coral reefs may be threatened by sunscreen induced coral bleaching.

Each year between 4000-6000 metric tons (4400-6600 US tons) of sunscreen washes off swimmers and snorkelers into coral reef environments. Some of these common sunscreen ingredients were shown to cause complete coral bleaching at very low concentrations.

Avoid these reef-harmful sunscreen ingredients:

  1. Oxybenzone (benzophenone-3) – Sunscreen with several suspected human health effects.
  2. Butylparaben – Preservative with several suspected human health effects.
  3. Octinoxate (Ethylhexyl methoxycinnamate) – Sunscreen with several suspected human health effects.
  4. 4-methylbenzylidene camphor (4MBC) – Sunscreen with several suspected human health effects. Allowed in Europe and Canada, not in USA or Japan

There are many other chemical ingredients that are commonly used in wide variety of sunscreens that are bad for you and the coral reef.  As a general rule of a thumb it is a good idea to avoid products with a long list of chemical ingredients you can’t read or understand..  The two base ingredients that score best for safety of the coral today are: titanium dioxide and zinc oxide.  Please read Environmental Working Group reports for more detailed and current information about true meaning of “reef safe” sunscreen today.

Other factors to consider when trying to stay sun safe.

Do not confuse SPF number and amount of time the sunscreen will protect you against the powerful UV rays!  Many people believe that the SPF number equals the number of minutes you are protected (meaning: SPF 100 gives 100 minutes of protections, while SPF 30 only protects you for 30 minutes).   That is not exactly how it works.  In fact, SPF 30 filters out 97% of UVB, SPF 50 filters out 98%, and SPF 100 filters out 99%, according to the the American Cancer Society.

In addition, consider other factors when using a sunscreen, such as your water exposure, sweat, and the power of the UV rays.  Your weather channel app can tell you how strong the UV Index is in your area at all times.  It is a great idea to avoid sun exposure between hours of 10am and 4pm, while UV Index is at its highest.  Other ways to stay sun safe is to use hats, sunglasses, and clothing to cover up and seek shade whenever possible.
