Is Sun Bum sunscreen reef-safe?
Being Sun Bum is a widely used sun protection brand, we thought we have to provide information about it. There is mixed information available on Sun Bum sunscreen products on the internet and it seems customers are still confused if Sun Bum is reef safe or not. Although Sun Bum sunscreens are labeled as reef-friendly, after reviewing the ingredients we can’t confirm 100% that Sun Bum is reef safe. It is true that Sun Bum original sun care products are Oxybenzone-free but contain Avobenzone and Octocrylene that are both listed as dangerous ingredients. Sun Bum mineral sunscreens have Nano Zinc Oxide and/or Titanium Dioxide which as mentioned can be harmful to corals.
Why use reef safe sunscreen?
The whole world relies on coral reefs for various reasons like coastal protection, food or livelihood. They are the most diverse and oldest ecosystems providing home to thousands of different marine species. Although corals seem to be extremely resilient to climate changes, the threats to reefs are bigger than ever before. Coral reef dangers are mostly human-related activities like carbon emissions, over-fishing, coastal runoff, plastic pollution, and chemicals effects that includes sunscreens too.
You might ask how that little tube of sunscreen causes such a bad damage on the reefs but knowing that an estimated 8-14.000 tons of sunscreen enter the world oceans annually, the danger is beyond doubt. It is proven that common sunscreen ingredients like oxybenzone and octinoxate are responsible for DNA deformities and coral bleaching. Moreover, dangerous sunscreen ingredients are not only harmful to the environment but for your body too.
Common sunscreen chemicals may cause severe allergic reactions and hormone disruption according to EWG. By using reef safe sunscreen for snorkeling and other water activities, you protect your body and the ocean at the same time.
Mineral sunscreen recommendations
Tip: If you read our other UV protection articles you might know that our best recommendation is to cover your body with sun protective clothing on land and while snorkeling too. Like this, you can skip or at least minimize using sunscreen and leave less impact on nature.
What sunscreen ingredients are dangerous?
Due to the latest hype around reef safe sunscreens, it became part of the marketing strategy to advertise sun care products as ocean-friendly but in fact, not all of them safe for corals. After the intense media communication, many of us know that a reef friendly sunscreen must be oxybenzone free as, but there are some other bad ingredients too.
Ingredients to avoid in sunscreen:
- oxybenzone (knows as benzophenone-3 too)
- octinoxate (octyl methoxycinnate)
- avobenzone (benzophenone)
Additionally, a reef sunscreen must be non-nano, paraben free and lack of the following chemicals: Sodium lauryl sulfate, Sodium Laureth Sulfate, Retinyl Palmitate, Phthalates, Cyclomethicone, Formaldehyde and Octocrylene just to mention typical bad cosmetic product ingredients.
This comparison table displays 5 sunblocks that contain natural ingredients only:
Oxybenzone and octinoxate effects
Common harmful sunscreen ingredients that have significant impact on coral reefs, listed as direct cause for coral bleaching according to scientists.
Oxybenzone: a general component of sunscreen that provides broad-spectrum UV rays coverage. It is toxic to coral larva especially to juveniles by disrupting the symbiosis between the coral and algae. As an irritant, it can cause allergies and by penetrating the skin results chemicals circulation in the bloodstream (97 % of the American have oxybenzone in their body)
Octinoxate: common UV filter. It is absorbed through the skin and can mimic hormones. Oestrogen hormone increase, thyroid fluctuation, and reproductive system diseases are the most common mentioned risks of using sun care products that contain octinoxate. And least but not last, it is linked to coral bleaching even at very low concentration.
Reef safe sunscreen ingredients
Ocean-friendly sunscreens contain mineral UV filters Zinc oxide and/or Titanium dioxide instead of chemicals. Mineral based sunscreen does not penetrate the skin but builds a layer that reflects UV rays like a mirror. Sunscreens with mineral ingredients provide strong UV protection with less health concerns. EWG also recommends Zinc Oxide containing sun lotions as reef safe sunscreen brands for snorkeling, diving or beach activities.
Adding mineral UV filter to a sun lotion is just half of the solution. In order to be reef safe, the sunscreen must labeled as non-nano too!
What is non-nano sunscreen?
According to EU definition, non-nano particle means that the size is bigger than 100 nm, the Australian rule indicates that more than 90% of the molecules are above 100 nm in a non-nano product. The biggest health concern regarding nano parts is that they can get into the body via penetration or inhalation, but scientists did not prove harmful effects yet.
Although nano Zinc oxide or Titanium dioxide are not considered to cause health issues by human but can be ingested by corals and fish resulting disorders, that’s why buy only non-nano sunscreen!
Safe sunscreen for babies
Shocking fact is that childhood sunburn can double skin cancer risk so sun protection for babies is a must at all time! Infants younger than 6 months are not protected by melanin that’s why keeping them away from direct sunlight and covering their body with UV protective clothing is crucial. Best to give them a hat and sunglasses too and apply sunscreen to the non-covered areas! Knowing that how misleading can be the information on eco-friendly sun care products, it is even a bigger challenge to find safe sunscreen for kids delicate skin.
These are 4 of the best safe sunscreen for kids and babies, all enjoy EWG recommendation:
- Badger Baby sunscreen SPF30
- Blue Lizard Baby Australian sunscreen
- All Good Natural Kids sun lotion
- Adorable Baby All Natural Sunscreen
Reef safe sunscreen additional information
Sun protection is very diversified topic and each answer brings up additional questions. However, we cannot cover all but here are some of the most common reef safe sunscreen related questions that can help you to find the best sun protection.
Titanium dioxide vs Zinc oxide – Which is better?
Mineral sun protection products contain Titanium Dioxide or Zinc oxide or both as active physical ingredient. As mentioned, they don’t penetrate the skin but stay on its surface working like a mirror that reflects light. Generally, Zinc oxide offer a better protection, more effective against long-wave UVA rays than Titanium dioxide as well as it is noncomedogenic and antimicrobial. Titanium Dioxide blocks UVB but not the full spectrum of UVA rays. It can be a good choice for those who cannot use Zinc containing products due to allergy. Sensitivity tests are recommended before applying mineral sunscreen on the whole body.
The most common negative feedback on mineral sunscreen without nanoparticles is the whitish layer that it leaves on the skin. To avoid this and make the product more-user-friendly, companies often use nano Zinc in sunscreens. This can minimize the whitening effect but at the same time, it is not safe for corals. When buying a reef safe sunscreen search the non-nano label on it that guarantees that the mineral ingredients are safe for corals and the ocean. If you learn how to apply your mineral sunscreen, the white effect isn’t be so bad but will make you satisfied you chose an eco-friendly solution.
How to use a reef safe sunscreen?
Mineral sun care products work physically which means you should cover the skin to get protection. With this in mind, you can see the whitening effect as an upside since you will always know where you applied enough sun lotion and where you need more. Zinc oxide sunscreen might feel dry compared to a classic one, so it is a little trick to put some light hydration crème on your skin first (but it is not a must).
To apply the sunscreen, squeeze a small amount first on the palm of your hand, spread it on the areas you want to cover and rub in until you get a thin but continuous coverage. Don’t worry, if you rub in the sunscreen thoroughly the white effect will fade in about 15 minutes. Remember to reapply it every 40-80 minutes depending on your activity and brand instructions.
Why don’t use spray sunscreen?
It became a trend lately choosing sunscreen aerosols because of the easy application but scientists and organizations do not recommend them.
These are the main reasons why you should avoid spray sunscreens:
- studies prove that only about 30% of the recommended amount of sun protection used when applying aerosol resulting inadequate
- bigger concern is that you might inhale the tiny particles which are even more dangerous than penetration through skin
- spray sunscreen might be flammable (although sunscreen itself not flammable, chemicals used in sprays like alcohol, propane, hydrocarbons etc… are, just think about hairsprays)
The best is to buy mineral based eco-friendly sunscreen in lotion or paste form!
