Natural and organic UK cosmetics: the best sustainable beauty brands
Written in collaboration with Organii
If we told you there is mineral sunscreen and chemical sunscreen, would you know the difference? Neither did we, until recently, and itâs pretty important.
At least 100,000 new cases of skin cancer are now diagnosed each year, according to the British Skin Foundation. As such, sunscreen is essential protection from overexposure to the UV rays.
Plus, sunscreen with UVA protection also provides protection against premature ageing (more on this below), which we wouldn’t say no to, either.
Choosing the right sunscreen is not only essential for your health, it can also have a big impact on the environment, and ocean life, especially. Hereâs what you need to knowâŠ
What is a mineral sunscreen?
A mineral sunscreen works by reflecting UV rays away from the skin. They are made of natural ingredients that have been processed in a lab: zinc oxide (from the mineral zincite) and titanium dioxide (from minerals rutile or anatase, if natural).
Why do they take longer to rub into the skin, you ask? Or maybe you didn’t know that yet, so we asked. Itâs a tough life laying on the beach, rubbing in sun creamâŠ
Well, itâs because both ingredients are very white â theyâre reflecting the sun, remember. Then thereâs the fact that they work on the surface of the skin, so your body doesnât absorb the cream (or as much heat from the sun). In our humble opinion, both these things make rubbing in that whiteness worth the extra effort.
As it contains less chemicals, mineral sunscreen is also broadly considered to be less irritating for sensitive skin.
Where you can source mineral sunscreen
Organii sell mineral sun protection on their website and just last month Holland & Barratt became the first major UK retailer to ban chemical sunscreens and only sell mineral ones.
An important note: Mineral sunscreens are not to be confused with âmineral oilâ, which is actually a heavily processed form of petrol and therefore to be avoided.
What is a chemical sunscreen?
Rather than reflect the UV rays, chemical sun creams are absorbed into the skin creating a chemical reaction in the body that then releases them as heat.
They can be invisible to spray on and quickly absorbed into the skin. Dreamy. But, at what cost?
Chemical sunscreens contain chemicals that are definitely absorbed into the body and possibly have adverse effects. They are also harmful to the environment, especially when they are washed off into the sea. This section could contain a whole list of ingredients to avoid, but have you ever read an ingredients list on any cosmetic product? Even we find it confusing.
How do you know whatâs a âchemicalâ sunscreen?
Itâs on every shelf of every supermarket and airport shop, and probably one youâve been using for years. Be aware â even chemical sunscreens can market their products as “mineral protection”, so you’re best to look for a certified natural or organic product if you want a genuine mineral sunscreen.
What about ‘nano particles’ in sunscreen â are these bad?
Nano-particle technology breaks ingredients down into tiny particles. This is what allows sunscreen to be rubbed in more easily and not leave such a white sheen on your skin.
Nano-particles are still a bit of an unknown and some fear this allows the chemicals to cross cell membranes, which means they could be absorbed into the body. Other research suggests they don’t carry much of a risk.
It can be used in mineral sunscreen, too. If you want to stay away from nanoparticles, Ethical Consumer lists brands that use explicitly non-nano zinc oxide or titanium dioxide.
Is SPF 30 high enough?
What factor SPF to use is a great question, with an even better answer. Are you ready to have your mind blown?
The SPF (Sun Protection Factor) rates how good a sunscreen is at blocking UVB rays â the ones that most typically cause sunburn. A product with SPF 15 blocks a staggering 92% of UVB rays. SPF 20 blocks about 95% and SPF 50 blocks about 98%.
So, thereâs a 6% difference between SPF 15 and SPF 50. And, yes, SPF 30 is probably high enough.
Not linked to the SPF rating, but also important to note:
UVA rays account for 95% of the radiation that reaches the earthâs surface. They have a longer wavelength that can pass through clouds and glass. Itâs mainly linked to ageing but can also cause cancer. So, look for a sunscreen that protects you from both UVA and UVB rays.
And finally a fun fact (for any quiz knowledge you might need to accumulate):
The sun emits a third type of radiation â UVC. These are the most damaging rays, but they are completely filtered by the atmosphere and donât reach the earthâs surface. So, you don’t need to worry about them.
How much time can you spend in the sun without burning?
Thereâs a calculation you can use as a guide for how much time is safe for your skin to spend in the sun: your skinâs own natural protection time (typically 5 – 30 minutes) x sun protection factor.
But, we donât encourage you to play fast and loose with working out the limits of your skinâs own protection time because there are other variables â most notably the weather and atmospheric conditions.
So, the best way to stay safe in the sun is simply not to stay in it for too long.
Is ‘reef-safe’ mineral sunscreen genuinely safe for reefs?
Another great question, with another unexpected answer.
Sun creams are increasingly labelled âReef-safeâ, âReef-friendlyâ or âOcean-friendlyâ.
This is largely because they donât contain chemicals such as Oxybenzone, which is said to act as hormone disruptors and cause sex change in fish, reduce their growth or egg output and destroy coral reefs around the globe. Researchers found a single drop in 4.3 million gallons of water â about six and a half Olympic-size swimming pools â is enough to be deadly to coral.
âHowever, itâs not as simple as switching to mineral sunscreens,â warns Graeme Hume, from Organii. âMineral sunscreen can wash off more easily in the sea because it sits on top of the skin. Plus, although more natural, Zinc Oxide may also have a bleaching effect on the coral and Titanium Dioxide could also negatively impact marine life. As with most things, the best answer is to use less sun cream, which means staying out of the sun more.â
Also, itâs important to put this into context. By far, the greatest damage to coral reefs is rising water temperatures caused by the climate crisis.
So, err, about that flight you took to get to that holiday where you need to apply sun creamâŠ
Microplastics in sunscreen:
Forget the packaging for a moment, did you know that upwards of 72% of sun creams also contain microbeads, according to research conducted by the Plastic Soup Foundation?
7 countries that have banned chemical sunscreens:Palau (an island country in the western Pacific)
1. Hawaii
2. US Virgin Islands
3. Key West, Florida
4. Ecotourism reserves in Mexico
5. Bonaire (Caribbean)
6. Aruba (Carribbean)
7. Palau (an island country in the western Pacific)

Nope, microplastics werenât banned in sunscreen in 2018, because it’s considered a âleave-onâ cosmetic product and the microplastic ban is limited to ârinse off’ products.
So, microplastics can be used to bind ingredients together or make a product waterproof â and there can be between 10 and 100 trillion particles in one single product. The Plastic Soup Foundation claims that the very smallest particles are potentially the most dangerous because they can be absorbed into the food chain so easily â they can even be absorbed by animal tissue… You are what you eat, as the saying goes.
Once again, ingredients lists are not your friend, here. Microplastics are hidden in all types of ingredients, the list could be as long as this article. Probably better to look for a sunscreen that doesn’t contain synthetic ingredients (i.e. a mineral sunscreen).
Greenwashing in sun cream, what to look out for:
When it comes to effective and sustainable sun cream, looking for a certification from the likes of organic certifying bodies such as the Soil Association, Cosmos or Natrue is a much quicker route to choosing a safe sun cream. This is because to be certified, brands are not allowed to use the most toxic chemicals.
If youâre looking for a vegan sunscreen, look for the Leaping Bunny logo. If this isn’t present the common animal-derived ingredients to look out for are keratin and lanolin (also honey and beeswax).
Finally, Ethical Consumer have a very comprehensive sunscreen buying guide, where they score and rank the ethical and environmental credentials of 32 sunscreen brands. Spolier: Organii and Odylique come out top. Boots and Superdrug own brands come out bottom.
