There’s no shortage of sunscreens out there with a long ingredients list featuring numerous problematic chemicals. Thankfully, many companies have wised up and ditched the reef-damaging, carcinogenic, skin-damaging chemicals for better ingredients.

The best sunscreens for human health are those that use a mineral block to protect the skin from ultraviolet rays. Sunscreens formulated with zinc oxide tend to offer better protection against UVA rays compared to titanium oxide and organic chemicals and zinc oxide is also stable in sunlight. These non-nano mineral-based sunscreens are also reef-safe (depending on other ingredients), meaning that they don’t damage coral reefs like other chemical sunscreens containing oxybenzone and octizonate, along with other ingredients.

Here are my top picks for the best natural sunscreen brands, with more info on new innovations in sunscreen and reef-safe sunscreens below the recommendations.

How to choose a safe sunscreen

The recommendations above are just a handful of many natural sunscreens where the active ingredient is zinc oxide and/or titanium dioxide. In general, what you want to avoid spray sunscreens whenever you can, especially if they contain nanoparticles, look for a short ingredient list and pick a:

  • a non-chemical sunscreen with micronized zinc oxide (or titanium dioxide)
  • a sunscreen with an SPF factor of 50 or lower (anything higher is misleading, according to the FDA and the Environmental Working Group)

US regulators have only approved zinc oxide and avobenzone as sunscreen ingredients that provide true broad-spectrum protection against UVA wavelengths. Avobenzone has a short-lived absorption capacity, however (it begins to break down after 30 minutes or so) (R), and there are growing concerns over the potential for avobenzone to form undesirable transformation products (including ecotoxins), particularly when it reacts with chlorine (R). As such, if your only option is a sunscreen with avobenzone, try to find one that includes other ingredients (such as triplet quenchers) that help sustain its capacity to protect the skin and avoid undesirable breakdown products (R).

There is another sunscreen option that many people are excited about – Mexoryl SX. However, the US FDA has so far failed to approve Mexoryl SX and other sunscreen chemicals for use in the US.

Mexoryl

Mexoryl SX (Ecamsule) has been widely available in Europe and in Canada for well over a decade. Sadly, though, it is currently only licensed in the US for use at a specific level in Ombrelle, a product by L’Oreal. That’s because the company stumped up the exorbitant cost to apply for an FDA license, which they received in 2006.

Mexoryl SX is a highly effective chemical sun filter and can be easily combined with other UV filters to create very high SPF formulas (R). Tests performed by L’Oreal (included in their license application) showed that Mexoryl SX absorption is very minimal (at less than 0.1%) and poses no risk to human health. Who wouldn’t want that in their sunscreen?

There is one major drawback with Mexoryl, however. Mexoryl only protects against UV wavelengths in the 290-400 nanometer range. Since this doesn’t cover the entire UV spectrum (UVB is 280 to 320 nanometers), Mexoryl must be combined with another UV filter to provide broad-spectrum coverage. Ombrelle, for example, combines Mexoryl with homosalate, octocrylene, avobenzene, and octisalate. Disappointing, right?

And things aren’t much better In Europe, sadly. There, Mexoryl SX is available as the very popular Anthelios line by La Roche Posay. This formula includes octocrylene, titanium dioxide, avobenzone, and Mexoryl, making it marginally better than the L’Oreal formula. Both Anthelios and Ombrelle contain parabens and other undesirable chemicals, though, so there’s still some work to do before we get the sunscreens we deserve.

My hope is that a product will soon be made available that includes Mexoryl alongside zinc oxide or another natural sunblock. Saffron and quercetin are two intriguing potential sunscreen ingredients that seem to confer UVB protection. In one study, a 4% saffron lotion showed an SPF value equivalent to an 8% homosalate lotion (R).

Are there any other options for natural sunscreen? Well, if you’re equally concerned about your own health and the health of the environment, you may be interested to learn of the existence of a newly patented sunscreen based on ingredients that have all been tested to ensure they don’t damage marine organisms, including coral and the ecosystem that depends on coral reefs. This sunscreen formula includes: diethylamino hydroxybenzoyl hexyl benzoate, methylene bis-benzotriazolyl tetramethylbutylphenol, ethylhexyl triazone and the preservative sorbic acid. The sunscreen has been tested and found to be just as effective as regular chemical sunscreens (R). Sadly, there is currently no consumer version of this sunscreen available, but I’ll keep checking and will add it here if/when it comes to market.

How to choose a reef-safe sunscreen

According to a report by Marine Life, a marine conservation NGO, there may be some 82,000 kinds of chemicals swilling about in the world’s oceans thanks to our use of personal care products like sunscreen. In 2015 alone, an estimated 14,000 tons of sunscreen made their way to the world’s coral reefs, where they caused irreversible damage and led to the death of many reefs.

The main culprits for coral reef damage are oxybenzone and octinoxate, two of the most widely used chemicals in sunscreens. Oxybenzone damages coral DNA (which can cause cancer and harm coral development), can disrupt the hormonal system of coral, can lead to deformities in young coral, and can lead to bleaching of coral.

These aren’t the only two chemicals causing problems for coral. Other troublesome factors in sunscreens include parabens (methyl paraben and butyl paraben, for example), and phenoxyethanol.

So, to choose a reef-safe sunscreen, avoid those that rely on oxybenzone and octinoxate, any that contain parabens, and those with phenoxyethanol on the ingredients list. It’s also best to avoid aerosol spray sunscreens as these disperse microscopic particles into the environment and typically mean a product is nano-based.

Non-nano titanium dioxide sunscreen is your best option for a reef-safe sunscreen, as long as the product is also free of the other chemicals mentioned above.

Other ways to reduce your impact include simply using less sunscreen. Stay sun-safe by using protective sunwear instead and use sunscreen with an SPF of 30 on any areas of skin that are exposed. Any higher and you’ll get minimal additional benefits but there’ll be a lot more of the chemical ingredients making their way into the environment.

Given the potential hazards associated with sunscreens, it’s worth reiterating that sunscreens should be your last resort for sun protection. You’re far better staying in the shade, wearing a sun-shirt, and carrying a parasol than covering your body with sunscreen several times a day. But, when sunscreen is necessary, your best options are to choose one of the ones recommended above!

  1. Badger has a sunscreen that has only 4 ingredients – Zinc Oxide, Beeswax, Sunflower Seed Oil and Vitamin E. I saw on someone’s blog who has MCS (multiple chemical sensitivity) that this worked for them. I’ve also used it and I like it
