With summer here and people spending more time outdoors, sunscreen is a must-have item. But there’s growing concern about the impact of sunscreen chemicals on marine ecosystems. If you want to be reef-safe this summer, a biodegradable sunscreen is your best bet. But with so many options on store shelves, how can you know if a sunscreen is truly biodegradable or not? In this comprehensive guide, we’ll walk you through everything you need to know to find a reef-safe sunscreen.
If you’re short on time, here’s a quick answer to your question: Look for sunscreens with active ingredients zinc oxide and titanium dioxide, and avoid chemical UV filters like oxybenzone. Check labels for terms like ‘reef-safe’, ‘ocean-friendly’, and ‘biodegradable’. And steer clear of aerosol spray sunscreens, which can be inhaled.
What Makes A Sunscreen Biodegradable?
When it comes to choosing a sunscreen, it’s important to consider its impact on the environment. Biodegradable sunscreens are formulated with ingredients that break down naturally and do not harm marine life or pollute our waterways. Here are some key factors that make a sunscreen biodegradable:
Mineral vs. chemical sunscreen ingredients
One of the main differences between biodegradable and non-biodegradable sunscreens is the type of ingredients used. Mineral sunscreens, also known as physical sunscreens, contain active ingredients like zinc oxide and titanium dioxide. These minerals create a protective barrier on the skin that reflects UV rays. On the other hand, chemical sunscreens use ingredients like oxybenzone, octinoxate, and avobenzone to absorb and dissipate UV rays. While both types of sunscreens provide sun protection, mineral sunscreens are generally considered more eco-friendly and biodegradable.
Avoid oxybenzone and other chemical filters
Oxybenzone, a common ingredient found in many chemical sunscreens, has been linked to coral bleaching and damage to marine ecosystems. It is important to avoid sunscreens that contain oxybenzone or other harmful chemical filters, as they can have a detrimental impact on coral reefs and other aquatic life. Look for sunscreens that are labeled “oxybenzone-free” or “reef-safe” to ensure you are choosing a biodegradable option.
Zinc oxide and titanium dioxide break down naturally
One of the main reasons why mineral sunscreens are considered biodegradable is because their active ingredients, zinc oxide and titanium dioxide, break down naturally. These minerals are not harmful to the environment and do not accumulate in our water systems. In fact, zinc oxide is commonly used in diaper rash creams and other skincare products for its soothing and healing properties. When choosing a sunscreen, look for those that contain high percentages of zinc oxide or titanium dioxide, as they are more likely to be biodegradable.
How To Identify A Biodegradable Sunscreen
Choosing a biodegradable sunscreen is not only good for your skin but also for the environment. However, with so many options available, it can be challenging to determine which sunscreens are truly biodegradable. Here are some tips to help you identify a biodegradable sunscreen:
Look for key terms on the label
When shopping for sunscreen, one of the first things you should do is check the label for key terms that indicate biodegradability. Look for words such as “biodegradable,” “reef-safe,” “ocean-friendly,” or “environmentally friendly.” These terms suggest that the sunscreen has been formulated to break down naturally without harming the environment. Additionally, look for sunscreens that are labeled as “mineral-based” or “physical” rather than “chemical.” Mineral-based sunscreens typically contain ingredients like zinc oxide or titanium dioxide, which are less harmful to marine life and ecosystems.
Beware of misleading marketing claims
Unfortunately, not all sunscreen brands are honest about their biodegradability claims. Some brands may use vague or misleading marketing language to make their products appear more environmentally friendly than they actually are. Be cautious of phrases like “biodegradable ingredients” or “biodegradable formula” without any further clarification. To ensure the sunscreen is truly biodegradable, look for certification or third-party testing. Some reputable organizations, such as the Environmental Working Group (EWG) or the Marine Stewardship Council (MSC), provide certifications for biodegradable sunscreens. Check their websites or look for their logos on the product packaging.
Check reputable databases for rated products
If you want an easy way to find biodegradable sunscreens, check reputable databases that provide ratings and reviews for various products. Websites like the EWG’s Skin Deep Database or the Surfrider Foundation’s Blue Star Program offer comprehensive guides to help you find sunscreens that are both effective and environmentally friendly. These databases evaluate products based on their ingredients and their impact on the environment. They often provide detailed information about the biodegradability of sunscreens, making it easier for you to make an informed decision.
By following these tips, you can confidently choose a biodegradable sunscreen that not only protects your skin but also helps protect the planet.
Other Tips For Reef-Safe Sun Protection
Avoid spray sunscreens
While spray sunscreens may be convenient, they are not the best choice for reef-safe sun protection. When sprayed, the tiny particles can easily get into the air and water, posing a threat to marine life and coral reefs. Instead, opt for lotion or cream sunscreens that can be applied directly onto the skin.
Limit amount and frequency of application
Applying sunscreen is crucial for protecting your skin from harmful UV rays, but it’s important to use it in moderation. Using excessive amounts of sunscreen and reapplying it too frequently can increase the chances of it washing off into the water and harming marine ecosystems. Remember, a little goes a long way, so apply just enough sunscreen to cover your exposed skin and reapply only when necessary.
Look for coral-friendly formulas without parabens
When choosing a sunscreen, it’s important to look for formulas that are labeled as “coral-friendly” or “reef-safe.” These products are specifically designed to minimize their impact on the environment, including coral reefs. Avoid sunscreens that contain parabens, as they have been found to contribute to coral bleaching and other detrimental effects on marine life.
In addition to these tips, it’s always a good idea to educate yourself about the ingredients in your sunscreen and their impact on the environment. Reading the labels and doing a quick online search can provide valuable insights into the sustainability of the product you’re considering.

Homemade Natural Sunscreen Recipes
Are you concerned about the environmental impact of commercial sunscreens? Would you like to try making your own natural sunscreen at home? Look no further! In this article, we will provide you with some easy and effective homemade sunscreen recipes that are both biodegradable and eco-friendly.
Basic Coconut Oil Sunscreen
Coconut oil is a fantastic natural ingredient that can provide some sun protection. It has a natural SPF of around 4-6, which is perfect for daily use or when the sun isn’t too intense. To make a basic coconut oil sunscreen, simply mix equal parts of coconut oil and shea butter. You can also add a few drops of your favorite essential oil for a pleasant scent. Apply this mixture to your skin before heading out into the sun.
More Advanced Recipes with Zinc Oxide
If you’re looking for higher sun protection, consider adding zinc oxide to your homemade sunscreen. Zinc oxide is a mineral that provides broad-spectrum UVA and UVB protection. To make a more advanced sunscreen, mix together 1/4 cup of coconut oil, 1/4 cup of shea butter, 2 tablespoons of beeswax pellets, and 2 tablespoons of zinc oxide. Heat the mixture gently until everything is melted and well combined. Pour it into a container and let it cool completely before use. Remember to reapply every few hours for maximum protection.
Effectiveness and Precautions for DIY Sunscreen
It’s important to note that homemade sunscreens may not provide the same level of protection as commercial ones. While zinc oxide offers good protection, the concentration used in homemade recipes may vary. Additionally, homemade sunscreens are not FDA-approved, so their effectiveness cannot be guaranteed. It’s always a good idea to test your homemade sunscreen on a small area of skin before using it on your entire body.
Furthermore, it’s crucial to remember that sunscreen alone is not enough to protect your skin from the sun’s harmful rays. Wearing protective clothing, seeking shade, and avoiding the sun during peak hours are also essential.
