Let’s be honest. The ‘best’ ‘reef safe’ sunscreen for the ocean is none at all — no contamination whatsoever from our products. But realistically, we love swimming in the sea and being in and part of the ocean is a way of life and enjoyment. Sadly, research has shown that every year an estimated 14,000 tons of sunscreen ended up on coral reefs across the world. So, we each need to be smarter about what we’re putting on our skin and taking into the water, to minimise damage to delicate marine ecosystems.
We know sunscreen plays a vital role in helping to protect our skin from skin cancers and (try to!) avoid premature ageing. That means wearing sunscreen daily, all year round. Because even in winter the UV rays can be harsh, and when you’re on the ocean with reflected light, it’s intensified even more. Sun protection isn’t just about sunscreen though. Wearing sun-protective clothing, finding shade and only using sunscreen on exposed skin goes a long way to reducing the amount of sunscreen used and gives you the best skin protection.
If you spend a lot of time at the beach and in the water (which I’m picking you do) — you’ll want to buy a sunscreen that you know is least damaging for the ocean. It’s important that sunscreen doesn’t include ingredients that are going to be harmful to your body, or to coral reefs and marine life. That doesn’t sound like rocket science but with so many different sunscreen products on the market, and with so many brands claiming to be ‘eco-friendly’ it can be confusing to know which ones are actually living up to their claims, and which are just hiding behind clever marketing and packaging promises.
Added to the mix are research studies that show even some mineral ingredients such as zinc oxide and titanium dioxide in nano-particle form may cause coral bleaching, although as Smithsonian Magazine summarises, there are conflicting views as to the size of data studies and interpretation of results. So, are there any safe sunscreens we can use? According to the Skin Cancer Foundation, one in five Americans will develop skin cancer by the age of 70 — there’s no doubting the importance of sunscreen. There are definitely some mineral based sunscreens that have less impact on human health and ocean life than others.
I’ve rounded up the latest research and information from the experts such as Save the Reef to answer some important sunscreen questions. It’s clear that there are definitely ingredients to avoid and many of these are found in popular sunscreens. To help keep life simple, I’ve picked the 11 best non-nano mineral, kid-friendly sunscreens that are good for you, and not as bad for the sea (but I’ll keep watch on the science as research develops).
You can trust that these sunscreens meet these important categories:
What’s actually in sunscreen that’s bad for the ocean?
The majority of sunscreens on the market contain harmful ingredients such as oxybenzone and octinoxate. Traces of these have been found in many marine species from white fish to trout, mussels to coral, mahi-mahi, dolphins, sea turtle eggs, and migratory bird eggs. Sunscreen pollution from these chemicals is a contributing factor in coral bleaching and has been banned from use in Hawaii since 2018.
What ingredients should I avoid?
The Haereticus Environmental Laboratory and Steam2Sea have an extensive list of harmful ingredients to avoid in your sunscreen and body products. The main chemicals to avoid are:
cylcopentasiloxane / cyclomethicone
methylisothiazolinone
octoxinate / octyl methoxycinnamate
camphor derivatives
4-methylbenzylidene camphor
Octocrylene
Any form of microplastic sphere or beads.
Any nanoparticles like zinc oxide or titanium dioxide.
Para-aminobenzoic acid (PABA)
parabens:
Methyl Paraben
Ethyl Paraben
Propyl Paraben
Butyl Paraben
Benzyl Paraben
cinnamates
Triclosan
It is time consuming cross-referencing ingredients on your products but this is the best way to know whether a sunscreen or product is safe to use.
The 11 sunscreens listed below are all free of these ingredients.
Ok, I’m chemically overwhelmed — can you please make this simple?
Totally! Here’s the key things to remember when choosing your next sunscreen.
Avoid sunscreens which rub in ‘clear’ to your skin*.
These work by being absorbed into your skin and absorbing UV rays. Common sunscreen brands like Neutrogena, Sun Bum, Coppertone etc use harmful sythentic ingredients that allow the sunscreen to be completely rubbed into your skin – so you can’t see it when it’s on.
*Skinnies sunscreen (below) is an exception to this — they use a waterless Organogel technology, so it goes on clear, and isn’t white or greasy but this layer isn’t absorbed — it stays on top of your skin.
Choose non-nano mineral based products that still show up on your skin when applied.
In most mineral sunscreens, titanium dioxide or zinc oxide is the primary active ingredient and is the safest, most effective sun protection out there. Look for sunscreens that include titanium or zinc as these are safe and stay on the surface of your skin to reflect UV rays. You might not like the look quite as much, but it’s far healthier for your body and the ocean.
Avoid nanoparticles
Some sunscreens now include nanoparticles in their formulas (even some zinc mineral based ones) to stop the white look and make the sunscreen appear clear on your skin. The effects of these tiny molecules on the body’s circulatory and immune systems are still being studied for their health risks but they are highly toxic to marine life and should be avoided.
Skip the aerosols
Aerosol sunscreens may seem less messy, more convenient and easier to apply but with an aerosol spray, you’re inhaling microscopic ingredients and they’re not an environmentally friendly packaging option.
So in summary, you want to look for sunscreen products that contain solid-particle, non-nano titanium dioxide or zinc oxide. Here’s the best 11 sunscreens I found…

Top tips to look after your skin from the sun
One of the best things we can do for our friends and family is to help keep their skin protected too. Remind them to put sunscreen on, and keep spare hats and creams handy.
Find shady spots to keep out of the sun — especially during peak sun hours between 10am to 4pm, when UV radiation is at its strongest
Wear a hat (here’s the best sunhats for sailing) and stay covered under protective clothing
Wear a sun-shirt or rash vest in the water – think how much less product you’ll need to apply!
Wear sunscreen daily — apply 20 minutes before heading outside
Reapply sunscreen regularly — even those that are water resistant
Check your sunscreen expiry date and how it looks and smells to ensure it’s always fresh and still offering sun protection.
Drink lots of water and keep hydrated
In Summary
Small positive choices we each make daily to stay out of the sun and wear products that are least harmful can make a difference. And as research develops, we’re empowered by more knowledge to make better decisions. For today, enjoy being outdoors — enjoy the ocean and sunshine and stay sunsmart.
