Updated May 2026: This guide has been fully revised with current regulations and clearer explanations as of May 2026.
After learning how labels work, why naming systems differ, and how to research ingredients, this final post brings together everything we’ve covered in the series and applies it to one of the most confusing categories: sunscreen.
As a mum, I know how overwhelming it can feel trying to choose a “natural” sunscreen that keeps your family safe from the sun without exposing them to ingredients you’d rather avoid. We all want to protect our loved ones from both harmful UV rays and unnecessary chemicals. With so many options and clever marketing, it’s not always easy to know what’s best.
When Organic Sun was first introduced many years ago, there were very few truly natural sunscreen options available in Australia. It was created because so many children with sensitive skin and eczema were reacting badly to the sunscreens on the market at the time. The goal was to make a gentler, mineral-based option that parents could feel good about using.
Today there are many more choices available, which is wonderful. However, with more options comes more confusion, from clever marketing claims to complicated regulations. My hope is that this updated guide helps you feel more confident when making choices for your family.
The Important Difference Between Therapeutic and Cosmetic Sunscreens
In Australia, sun protection products are regulated in two different ways depending on their claims.
Any product that uses the word “sunscreen” must be approved by the Therapeutic Goods Administration (TGA). A product claiming SPF higher than 15 must be regulated as therapeutic (medical) goods and carry an AUST L number. These products only need to list active ingredients and known irritants. Other ingredients may not be disclosed on the label.
Cosmetic products with sun protection (such as tinted moisturisers or light balms) are regulated differently. They can only claim up to SPF 15, must list all ingredients, and cannot claim to be waterproof or water resistant.
This difference means you need to research and compare them in different ways.
A TGA-approved SPF50 chemical sunscreen can make strong “waterproof” and “broad spectrum” claims.
Meanwhile, a carefully formulated natural cosmetic balm using mineral zinc oxide and all-natural ingredients cannot make those same strong claims, even if it has been tested and performs just as well, because the rules don’t allow it. And unlike the therapeutic version, it has to show every single ingredient, giving you full transparency.
Recent Sunscreen Recalls – What Happened
In 2025 and early 2026, several popular sunscreens in Australia were recalled or had their listings cancelled after independent testing (including by CHOICE) showed they did not meet their claimed SPF levels. Some products labelled SPF50+ were found to offer much lower protection.
This highlighted that even products with an AUST L number aren’t always perfect. The TGA has taken action, and they are currently reviewing sunscreen regulations to improve testing standards and labelling.
My gentle reminder: These recalls show why it’s important to stay informed and not rely solely on marketing claims — even from well-known brands.
Why Sunscreen Choice Feels So Tricky
We want effective protection from the sun’s harmful rays, but many of us also want to avoid unnecessary chemicals. The challenge is that marketing terms like “natural”, “organic”, and “safe for babies” are not strictly regulated.
What I Look For in Natural Sunscreen
Here’s what I personally would look for when choosing sunscreen for my family:
- Mineral-based formulas, especially with zinc oxide for good broad-spectrum protection.
- If the SPF is over 15 and it’s marketed as primary sun protection, I look for an AUST L number (and I now double-check recent TGA recall lists).
- Brands that voluntarily list all ingredients for better transparency.
- Water-free formulas (balms or sticks) whenever possible, because they need fewer preservatives.
What to Be Cautious Of
- Heavy “all natural” marketing that still contains synthetic preservatives
- Fake “Australian” brands sold online with high SPF claims but no proper TGA approval
- Handmade or artisan sunscreens from markets that may lack proper SPF testing, stability testing, and microbial safety data
There is no perfect sunscreen.
The most effective protection from the sun comes from sensible sun habits
Limit exposure to damaging UV rays by:
- covering up with lightweight clothing and hat,
- keeping out of the sun in the heat of the day,
- applying sun protection to the body not covered by clothing,
- ensuring you apply sun protection at least 20 minutes before sun exposure.
But choosing the best natural sunscreen to care for your family is a personal decision. You also need to take into account your budget, convenience and personal ethics. Not to mention any allergies or skin sensitivities.
I no longer sell the original Green Foot Mama balms. We’re working on turning the much loved formulas into easy DIY guides so you can make your own gentle, water-free balms at home with ingredients you trust.
Final Thoughts
Choosing sunscreen is a very personal decision that depends on your family’s skin type, lifestyle, and values. The recent recalls have reminded all of us to stay vigilant, but they don’t mean we should stop using sunscreen.
You’ve come such a long way through this series. Thank you for taking the time to learn about all of this. My greatest wish is that these posts have helped you feel more empowered and less overwhelmed when caring for your family’s skin.
I’d love to hear which part of the series helped you the most, or what sunscreen approach works best for your family. Feel free to leave a comment below or on Facebook or Instagram.
Protection from the sun is still very important in Australia. For many reasons, we no longer manufacture the original Green Foot Mama balms. Instead, we are creating DIY guides with our much loved favourite water-free balm recipes so you can make your own using ingredients you feel confident about.

SPF & Sunscreen FAQ
What does SPF actually mean
SPF (Sun Protection Factor) measures how much longer your skin can stay in the sun before burning compared to unprotected skin. Importantly, it only measures protection against UVB rays (the rays that cause visible burning). It does not tell you how well the product protects against UVA rays, which penetrate deeper and contribute to skin aging and long-term damage.
How much difference is there really between SPF levels
SPF measures protection against UVB rays only.
If your unprotected skin burns after 10 minutes, SPF 15 should theoretically let you stay in the sun 15 times longer. 150 minutes which is about 2.5 hours.
In simple terms:
- SPF 15 blocks approximately 93% of UVB rays
- SPF 30 blocks approximately 97% of UVB rays
- SPF 50 blocks approximately 98% of UVB rays
The increase in protection from SPF 30 to SPF 50 is shockingly small. In reality only about 1% more UVB rays are blocked.
How is SPF tested in Australia?
SPF testing follows the AS/NZS 2604 standard. Ten volunteers with a specific skin type have sunscreen applied at a thickness of 2 mg per square centimetre (a thick layer rarely matched in real life). They are then exposed to artificial UV light to measure how long it takes for redness to appear.
In everyday use, most people apply much less sunscreen than this, and protection decreases with sweat, water, and rubbing. This is why reapplication every two hours (or after swimming or toweling) is essential.
What is broad-spectrum protection and why does it matter?
Broad-spectrum means the sunscreen protects against both UVA and UVB rays. UVA rays penetrate deeper into the skin, accelerate aging, and increase long-term skin cancer risk. They are present even on cloudy days and pass through glass.
Zinc oxide is one of the best mineral ingredients because it naturally provides strong protection against both UVA and UVB rays. Many titanium dioxide formulas need additional chemical filters to achieve true broad-spectrum coverage.
Physical (mineral) vs Chemical sunscreens – what’s the difference?
Physical/mineral sunscreens (mainly zinc oxide and titanium dioxide) sit on top of the skin and reflect or scatter UV rays. Chemical sunscreens absorb the rays and convert them into heat inside the skin.
Many people with sensitive skin or eczema-prone skin (like myself) find mineral sunscreens gentler and less likely to cause reactions.
Why do preservatives matter in sunscreen?
Most commercial sunscreens are water-based lotions or creams, which creates an environment where bacteria, mould, and yeast can grow. Preservatives are added to prevent this. However, many common preservatives are irritants and can cause contact dermatitis, especially in babies and people with sensitive skin.
Water-free formulas like balms and sticks generally do not need preservatives, which is one reason many families prefer them.
Can a natural SPF15 cosmetic balm be as effective as a high-SPF chemical sunscreen?
In most everyday situations a well-formulated natural mineral SPF15 balm can provide perfectly good protection for most people, especially for shorter periods outdoors combined with protective clothing, hats, and shade. It likely comes with fewer risks of skin reactions compared to some high-SPF chemical sunscreens that contain multiple synthetic filters and hidden excipients.
