Try an Eco-Friendly Sunscreen: Ocean Corals and Your Skin Will Thank You

Updated on August 1, 2014

What You Should Know About Biodegradable Sunscreen, Coral Reefs and Your Health

Each summer, beach lovers all over the world head to their favorite sandy shores slathered in sunscreen that is supposed to protect us from skin cancer, wrinkles, and other dangers of exposure to the sun. But the lotions and sprays we apply to protect our skin may very well be killing our oceans - and may not be saving us from the dangers we're trying to avoid. Fortunately, there are eco-friendly biodegradable sunscreens that are healthy for both our planet and our bodies. Here's what you should know about sunscreen, oceans, skin cancer and choosing a sunscreen that's right for you.

Most people probably don't think about protecting coral reefs when choosing their sunscreen, but they DO think about protecting themselves from skin cancer. After all, that's the reason we're all slathering ourselves with sunscreen and sunblock, right? But what if the lotions and sprays we're putting on our body are dangerous to our health and to that of the world's already-endangered coral reefs? That may very well be the case with many sunscreens.

A 2008 report published in the journal Environmental Health Perspectives indicated that four common ingredients found in sunscreen can wreak havoc on fragile reef ecosystems. The chemical ingredients cause dormant viruses within a specific type of algae to awaken and replicate until the algae explodes. Coal reefs depend on this algae, known as zooxanthellae, to provide energy through photosynthesis and contribute to the vibrant colors associated with reefs. Without this symbiotic algae, the reefs "bleach" (turn white) and die. Even low levels of sunscreen were found to activate the viruses. The amount of sunscreen typically used by swimmers could completely bleach coral in just four days.

Worldwide, 10 percent of the ocean's coral reefs are at risk of coral bleaching from sunscreen, according to the report, which said 4000 to 6000 metric tons of sunscreen wash off swimmers into oceans each year.

This correlation between coral bleaching and chemical sunscreen has led to the mandatory use of eco-friendly biodegradable sunscreen in some areas, such as the popular Cozumel Reefs National Marine Park (Parque Nacional Arrecifes de Cozumel) in Mexico. But, sadly, many people remain unaware of the dangers sunscreen can represent to our oceans.

Selecting a Sunscreen That's Good for You, Good for the Oceans

EWG Sunscreen Guide can help you decide

Fortunately, what's good for the coral reefs may also be good for your body. Many sunscreens contain chemicals that not only won't help prevent skin cancer, but could actually be carcinogenic themselves.

The Environmental Working Group is a nonprofit organization whose "team of scientists, engineers, policy experts, lawyers and computer programmers pores over government data, legal documents, scientific studies and our own laboratory tests to expose threats to your health and the environment, and to find solutions." Each year, the EWG publishes a sunscreen guide, listing ingredients for consumers to see and highlighting the pros and cons of each product.

The guide rates over 1400 products with SPF, including beach and sports lotions, sprays and creams, moisturizers, make-up and lip balms and then gives a score on a 1-10 scale (with 1 being highest) and a color-colored rating (green, yellow or red).

The organization's guide is meant mainly to protect consumers from health hazards of chemical ingredients, but several of the products that earn top ratings from the EWG for being the safest for humans are also biodegradable sunscreens that are safe for corals.

Biodegradable sunscreens to protect you and the planet

The eco-friendly sunscreens below are all good choices for both people and our oceans. They earned a "green" rating (high score of 1 or 2 out of a 10-point system) in the 2010 or 2011 EWG Sunscreen Guide, and they are eco-friendly products that can be used at any beach, including those such as Cozumel's national marine park that only allows biodegradable sunscreen.

Soleo Organics All Natural Sunscreen SPF 30+ - Top-rated sunscreen for oceans and your health

The 2010 EWG Sunscreen Guide ranked Soleo Organics a high-flying 1, the top score on their scale.

From Amazon: Take a once-in-a-lifetime journey across the South Pacific for a spectacular IMAX adventure. Joy, ecstasy, a spiritual high: these words describe the exhilaration of diving a pristine coral reef, and ocean explorers Howard and Michele Hall bring their love of the ocean into action. With Jean-Michael Cousteau, deep reef scientist Richard Pyle and Fijian diver Rusi Vulakoro, they explore and capture on film the dazzling underwater world of coral reefs, magical places here on Earth. This tropical excursion through the South Pacific will surprise and delight you as you fall in love with the reefs, and your heart will ache at the tragic, irretrievable loss of these fragile worlds.


We all know that sunscreens can prevent sunburn. But there is no consensus about any other benefits the products may - or may not - provide, including whether these commonly used lotions and sprays can help stop skin aging or prevent skin cancer. The 2010 EWG sunscreen report cites these statistics to show the confusion surrounding the benefits of sunscreen:

- Even though more people use sunscreen than ever before, the incidence of skin cancer in the United States and other countries continues to rise (Aceituno-Madera 2010; Jemal 2008; Osterlind 1992).

- A number of studies conducted in the 1990s report higher, not lower, incidence of the deadliest form of skin cancer, malignant melanoma, among frequent sunscreen users (Autier 1995; Westerdahl 2000; Wolf 1994).

- To date, studies show that regular sunscreen use reduces risk for squamous-cell carcinoma (SCC) but not other types of skin cancer. SCC, a slow-growing, treatable cancer, is estimated to account for just 16% of all skin cancers annually.

None of these facts suggest you shouldn't use sunscreen at all. In fact, the EWG report notes, "An effective sunscreen prevents more damage than it causes." But not all sunscreens are effective, and some may contain chemicals that have their own health risks. For instance, the FDA is investigating a form of vitamin A called retinyl palmitate, which is found in 41 percent of sunscreens. FDA data suggests vitamin A may actually elevate skin cancer risk.

Another Way to Protect Yourself - UV Shirts and Hats - Clothes can offer UV protection

One way to avoid the risks to yourself and the environment that can be caused by some suncreens is to wear clothes designed to filter UV rays. There are now a variety of shirts, pants and hats designed to block UV rays. Below is a sample from Amazon. You can find more by searching their clothing category for "UV protection."

    • TonyPayne profile image

      Tony Payne 6 years ago from Southampton, UK

      I think biodegradable sunscreen is a good idea, I hadn't heard of this before. Living in Florida as I did for a while, you couldn't go to the beach without using sunscreen, and the volumes that people use on a busy beach must have an environmental impact. Good information, blessed.

      Good information about the impact of sunscreen on the coral reef. The numbers are scary :(

      I try to avoid putting cream as much as possible: long sleeves, hat, pants, sunglasses, so I have littler skin exposed. Usually I need just a bit on the nose and face.

      Hadn't really connected sunscreen with damage to ocean eco-system - well done for highlighting the issue. I have to say that I never, ever put sunscreen on my kids. I always cover them up and make them wear hats (after getting a nice healthy dose of Vit D sunshine, of course). It seems that the increase in sunscreen correlates with the increase in skin cancers. Also... I read somewhere that using non-dairy spreads made with veg oil thins the human cell membrane and makes it more prone to damage. Eat butter!

      I had no idea. And I am SO very pale -- I have to wear sunscreen all the time, especially since I'm in California!

      And thank goodness there is a workable alternative. Sometimes we are between a rock and a hard place trying to find an eco-friendly solution, but it looks like that UV Natural will work even for my near-albino complexion.

      Thank you, lisadh.
