The best natural sunscreens & how to pick them

How sunscreens work and why choosing the right one matters. Check out our favourite natural sunscreens for adults & kids.

Living in Australia, the importance of having a great natural sunscreen on hand is high. Especially when you have children, I don’t think you can ever have enough sun protection around and I personally like to a natural sunscreen in each bag, so we’re never without it.

When I first started researching sunscreens, I was blown away by what a complex topic it was. I had previously thought that we were almost invincible with a coating of 50+ on us! I’d had no idea that just because a sunscreen has a high SPF rating, it doesn’t mean it blocks harmful UV A radiation – the one that causes deep skin damage and cancer.

We also see sneaky endocrine disruptors appearing in sunscreen formulations too, as well as some other ingredients, that are better avoided.

Luckily there are lots of fantastic products out there which are effective, safe and don’t cost a fortune. Join me below on a guide to choosing safe natural sunscreens where I’ll discuss how sunscreens work, what ingredients to avoid and which brands I recommend. (Or just skip to the end to see the recommended list!)

How do sunscreens work?

Sunscreens protect the skin against UV radiation by using either:

Physical blockers which physically block UV by reflecting and scattering it. These are the safest type of sunscreen. Zinc oxide and titanium dioxide are the active ingredients in these sunscreens and they both provide broad spectrum protection – blocking both UV A and B radiation. Zinc oxide is the pick as it is more effective at blocking UV A radiation than titanium dioxide and is also more stable in sunlight. The downside of these sunscreens is that because they form a physical block against the UV, they leave a white ghosting on the skin.

Chemical absorbers absorb UV radiation, thereby stopping it reaching your skin. These can have endocrine disruptors in them (which we definitely don’t want.)


To reduce the white ghosting on the skin, some companies have decided to make the zinc oxide or titanium dioxide particles extremely small – in the nano range. There has been some concern over these changes because when you make particles smaller, they become more easily absorbable and their actions on cells increase too, due to an increased surface area. Thankfully studies so far haven’t been able to show that nanoparticles can absorb beneath the lower layers of our skin and into our bodies, although studies are still ongoing and the jury is still out on it.

As we have a choice of whether to use nano or non-nano particles in our sunscreens, I like to stay on the safe side and choose non-nano natural sunscreen. The recommended list will only include natural sunscreens that are non-nano.

What is the SPF rating?

SPF refers to how well a sunscreen protects against UVB radiation – the one which causes the skin to burn. SPF rating does not have any reference to UVA radiation which penetrates deeper into the skin accelerating skin aging, suppressing the immune system and causing skin cancer. High SPF products can give a false sense of security – when we’re not burning our skin visibly, we think we must be ok and we stay out in the sun longer and reapply sunscreen less often. This was all news to me… I had absolutely no idea! It’s really important to look for a natural sunscreen which is broad spectrum and blocks both UV A and B radiation and apply regularly.

Sun exposure and babies

Babies’ skins have not yet developed melanin, the pigment in the skin that protects from UV. It is therefore advised that infants under 6 months be kept out of direct sun. To avoid direct sun, stay in shade, use hats and clothing. Over the pram, when my children were babies and toddlers, I used a CoziGo. Each panel around it can be opened or closed which is really useful to block off sun coming in at certain angles.

Vitamin D

Vitamin D is important for strengthening bones and even protecting against some cancer. Vitamin D is produced in our bodies in response to being exposed to sunlight. Some sun exposure is good and sun protection does block Vitamin D being produced – but 10- 15 minutes in the sun unprotected and not between 10am and 2pm, when the sun is at its hottest, is enough!

Ingredients that must be avoided

The following ingredients are all Endocrine/ Hormone disruptors which penetrate the skin and get into the bloodstream. These man-made industrial chemicals interfere with our hormones or their receptors and can have a negative impact on our health.

  • Oxybenzone (benzophenone-3)
  • Octyl-dimethyl-PABA
  • Octinoxate (Octyl methoxycinnamate/ OMC)
  • 4-Methylbenzylidene camphor
  • Padimate O (2-ethylhexyl-4-(dimethylamino) benzoate
  • Fragrance/ Parfum: This can be made up of hundreds of undeclared chemicals. Often including parabens and phthalates which are endocrine disruptors. It can however be made from natural organic essential oils which are totally safe, though sometimes may carry a bit of an increased risk of skin irritation. If it’s not marked as fragrance coming from a natural essential oil, then don’t use it.

Other ingredients to avoid

  • Retinyl palmate: this is a form of vitamin A. On sun-exposed skin, a recent study has shown that it may speed the development of skin tumours and lesions and form free radicals that damage DNA.
  • Methylisothiazolinone (MI): This has been the cause of some horrific allergic reactions and is a leading cause of dermatitis. It’s banned in the EU from being used in baby wipes.

Avoiding Insect Repellent Combinations

It is not advised to combine insect repellents with sunscreens. Studies have shown that combining sunscreens and repellents leads to increased absorption of the repellent ingredients. Insects are also often less of a problem during peak sun exposure hours and sunscreen needs to be more frequently applied than insect repellent.

Avoiding spray sunscreens

Whilst spray sunscreens may seem like the perfect solution, it’s best to use a cream instead. This is because sprays pose an inhalation risk, especially for children. Sunscreen particles were definitely not designed to be breathed into little lungs! You also tend to apply spray sunscreens in a thinner layer and it’s much easier to miss a spot.

Safe natural sunscreens

There are no 100% protective natural sunscreens. The best defence against the sun is to wear a hat, sunglasses and cover the body with clothing. It’s also advised to avoid spending extended periods of time in the sun during the hottest time of the day between 10am – 2 pm.

  • The following natural sunscreens are:
  • Broad spectrum – giving both good UVA and UVB protection
  • Non – nanoparticle Zinc Oxide as the active ingredient
  • Have no toxic ingredients
  • Come from socially responsible brands who make it their mission to create ethical and sustainable products
