Finding a sunscreen you actually want to wear every day can be difficult. When you have eczema-prone or highly sensitive skin, it can feel even harder.
Eczema can affect the skin barrier, leaving skin more prone to dryness, sensitivity and irritation. So while protecting your skin from Australia's UV levels remains essential, the formula you choose matters too.
The good news? You don't have to choose between high sun protection and caring for sensitive-skin.
Here’s what trusted Australian eczema and sun-safety guidance suggests looking for when choosing sunscreen for eczema-prone skin, and why a deeply nourishing zinc-based formula is a must.
Eczema is associated with a disrupted skin barrier. When that protective outer layer isn't functioning as effectively, skin can lose moisture more readily and become more susceptible to irritation.
That can make products that feel perfectly comfortable on someone else's skin sting or irritate eczema-prone skin.
The Eczema Association of Australasia (EAA) recommends keeping eczema skincare simple and being mindful of potential irritants such as fragrance and alcohol-heavy formulations. It also notes that “natural” doesn't automatically mean gentle, the overall formulation matters.
That's why finding the right sunscreen isn't only about choosing the highest SPF. It’s about finding effective protection that your skin can comfortably tolerate and that you'll use consistently.
When choosing sunscreen for eczema-prone skin, a gentle formula offering SPF30 is the best choice.
You may not realise that SPF30 and SPF50 actually provide very similar levels of UVB protection when applied correctly. SPF30 filters around 96.7% of UVB radiation, while SPF50 filters around 98%. So while SPF50 provides slightly more protection, both are considered high-protection sunscreens.
What matters just as much is choosing a broad-spectrum formula, meaning it protects against both UVA and UVB radiation, applying enough sunscreen and reapplying as directed.
For eczema-prone skin, there's another important factor: finding a formula your skin tolerates well enough that you'll actually use it consistently
For eczema-prone skin, what surrounds the UV filter is important too.
Choosing a formula with deeply nourishing oils help counter the natural drying effect of zinc. While natural butters like shea butter help lock in moisture.
Our SPF 30 contains a high concentration of natural oils. This deeply hydrating sunscreen may not appeal to everyone, but for babies and people with dry, sensitive skin it provides soothing nourishing protection, with no irritation.
Some people with eczema find mineral sunscreens containing ingredients such as zinc oxide easier to tolerate, although individual reactions vary. This is also highlighted in the EAA’s sunscreen guidance.
Zinc oxide is a mineral UV filter that provides broad-spectrum protection, helping protect skin against both UVA and UVB radiation.
For eczema-prone skin, sun protection is only part of the equation.
Your skin barrier helps retain moisture while providing an important defence against the external environment. Supporting that barrier through gentle skincare and regular moisturising is an important part of eczema management.
The EAA recommends regular moisturising and gentle, fragrance-free skincare to help keep eczema-prone skin hydrated and protected.
This is where Wotnot's BarrierKind™ Daily Defence System comes in:
Shield. Support. Strengthen.
Shield with an immediate layer of broad-spectrum zinc sun protection.
Support with formulations designed with sensitive and reactive skin in mind.
Strengthen with nourishing ingredients that help moisturise and support the skin's natural barrier and long-term resilience.
It’s about looking beyond a single day in the sun and considering how the products you use every day work with your skin.
For people who do not like the feel of a sunscreen with a high oil content Wotnot's SPF50 Zinc Sunscreen combines high-level sun protection with a formulation designed specifically with sensitive skin in mind.
It provides broad-spectrum UVA and UVB protection using zinc oxide and has a lightweight finish designed for everyday use across both the face and body.
Importantly for eczema-prone skin, Wotnot's SPF50 Zinc Sunscreen is listed by the Eczema Association of Australasia among its sunscreen products for sensitive skin.
The formula also contains skin-nourishing ingredients designed to moisturise and care for dry and sensitive skin, bringing together effective UV protection and everyday skin-barrier support.
Rather than thinking about sunscreen as something you reach for only when you're heading to the beach, the goal is to find a formula comfortable enough to become part of your everyday routine.
Even when a sunscreen is formulated for sensitive skin, eczema is highly individual. A product that works beautifully for one person's skin may not work for another.
To test a new sunscreen apply a small amount to the inside of the forearm and watch for redness, itching or irritation before using it more widely.
If a sunscreen causes an unusual reaction, stop using it.
Protect sensitive skin for the long term
Having eczema-prone skin shouldn't mean avoiding sunscreen. It means finding protection that works with your skin and your individual sensitivities.
Look for broad-spectrum SPF30 protection, pay attention to the overall formulation, avoid ingredients you already know trigger your skin, and consider a natural, zinc-based sunscreen if your skin tends to react to other formulas.
Most importantly, choose something comfortable enough that you'll actually wear it consistently.
Because caring for sensitive skin isn't just about managing today's irritation or today's UV exposure. It's about building habits that protect and support your skin throughout your life.
BarrierKind™ — Shield. Support. Strengthen.
Lifetime Skin Wellness™ — From birth. For life.
When we talk about protecting our skin, SPF tends to get most of the attention. But your skin already has its own incredible defence system working every day: the skin barrier.
The outermost part of this barrier, known as the stratum corneum, helps separate the living layers of your skin from the outside environment. Its job works in two directions by helping to keep moisture in while limiting the penetration of irritants and other external substances.
Think of it like a brick wall. Skin cells form the ‘bricks’, while lipids such as ceramides, cholesterol and fatty acids form the ‘mortar’ between them. Together, they create a strong but carefully organised protective layer.
When this barrier becomes disrupted, more moisture can escape and skin can become more vulnerable to external irritants, leaving it feeling dry, tight, sensitive or uncomfortable.
And that's why protecting your skin shouldn't stop at SPF.
Broad-spectrum sunscreen plays an essential role in protecting skin from UVA and UVB radiation, but caring for your skin every day also means thinking about the health and function of the barrier underneath.
At Wotnot, this approach comes together through our BarrierKind™3 pillar system : Soothe. Strengthen. Shield.
BarrierKind™ is Wotnot's approach to caring for skin beyond surface-level protection. It's about choosing formulas that help calm sensitive skin, support its natural barrier and protect it from the everyday factors that can leave it feeling vulnerable.
Help calm and relieve dry, delicate or sensitive skin.
When skin is already feeling dry or sensitive, the last thing it needs is a formula that adds unnecessary discomfort.
Wotnot products are formulated with sensitive skin in mind, combining gentle, organic, skin-nourishing ingredients with formulas designed for comfortable everyday use.
For sunscreen in particular, this matters because the best SPF is one you feel comfortable applying consistently. By considering sensitive skin alongside sun protection, everyday SPF can become a natural part of your skincare routine rather than something reserved for occasional beach days.
Help support and reinforce the skin's natural barrier.
Your skin barrier is constantly working to keep moisture in and protect the living layers of your skin from the outside world.
Supporting this barrier is an important part of keeping skin feeling healthy and resilient. Nourishing organic oils, aloe vera and botanical extracts used across Wotnot formulations help feed strengthening the skin’s natural barrier function.
It's about thinking beyond what your skin needs at this exact moment and supporting it for lifetime skin wellness(™).
Help protect skin from everyday factors that can leave it dry, irritated or vulnerable.
Our skin interacts with the outside world every day. Sun, wind and cold exposure, along with other environmental factors can all influence how skin looks and feels.
This is where SPF remains essential.
Wotnot's natural sunscreens use zinc oxide to provide broad-spectrum protection against both UVA and UVB radiation, creating a defensive layer against everyday sun exposure.
Whether you're walking to work, doing the school run, spending time outdoors or heading to the beach, sun protection shouldn't be reserved only for the days you expect to get burnt.
Take Wotnot's SPF 50 Zinc Sunscreen.
It combines broad-spectrum zinc sun protection with a lightweight formula created with sensitive skin in mind, bringing the BarrierKind™ philosophy into an everyday SPF.
Soothe: enriched with nourishing linseed oils to help soothe and care for dry or delicate skin.
Strengthen: linseed oils, naturally rich in omega-3 and omega-6 fatty acids, and vitamin e help nourish and support the skin and its natural barrier.
Shield: zinc oxide provides broad-spectrum UVA and UVB protection, while two hours of water resistance helps provide protection through everyday outdoor activities.
This clear zinc formula is also designed to rub in without the traditional heavy white finish associated with zinc sunscreen, making it suitable for everyday use across both the face and body.
It's TGA-listed and endorsed by the Eczema Association, providing additional reassurance for those looking for sun protection designed with sensitive skin in mind.
It's not about replacing SPF with barrier care. It's about recognising that effective skin protection can consider both.
Your skin barrier doesn't only matter when you're at the beach, and neither does sun protection.
Your skin is with you through every stage of life, and the small choices you make every day can become part of how you care for it over the long term.
With every product we formulate, our mission is to help support Lifetime Skin Wellness™. From birth. For life.
Sunscreen isn’t just for beach days. In Australia, UV exposure is part of everyday life, making sun protection an important part of looking after your skin for the long term.
But with so many options available, how do you choose the right zinc sunscreen? From SPF and ingredients to particle size and how it feels on your skin, here’s what to look for in 2026.
A good sunscreen should provide effective UV protection while being comfortable enough to wear every day.
At Wotnot, we approach daily sun and skin protection through three principles:
Together, these principles form Wotnot’s BarrierKind™ Daily Defence System.
Zinc oxide is a mineral UV filter that provides broad-spectrum protection across UVA and UVB wavelengths. Unlike chemical sunscreens that absorb UV radiation and convert it into heat, zinc oxide sunscreen reflects and scatters UV rays away from the skin, making it a gentler, low-tox option for you and your family.
The key difference is particle size. Nano zinc oxide generally refers to extremely small particles within the nanoscale range, commonly around 1–100 nanometres, while non-nano zinc sits outside this range.
So why make zinc particles so small? Using smaller particles can make zinc appear more transparent as traditionally, zinc sunscreen could leave a noticeable white cast on the skin. However, formulas have come a long way, with non-nano zinc sunscreens now providing consumers effective protection that's comfortable and easy to wear. A well-formulated non-nano sunscreen can be lightweight, comfortable and easy to incorporate into your everyday skincare routine.
The difference between SPF30 and SPF50 is smaller than you might think. When applied correctly, SPF30 filters around 96.7% of UVB radiation, while SPF50 filters around 98%.
Both provide high protection, so the most important thing is choosing a broad-spectrum sunscreen you’ll use consistently, applying enough and reapplying as directed.
The best zinc sunscreen depends on your skin, lifestyle and how you prefer to apply it.
Whatever your routine looks like, choosing a sunscreen that suits your needs makes daily protection that little bit easier — supporting Lifetime Skin Wellness™ from birth, for life.
Ultimately, the best format is one that makes consistent sun protection easier.
When checking sunscreen you might look for broad-spectrum protection or scan the ingredients. But have you ever noticed the little AUST L number on your sunscreen and wondered what it actually means?
In Australia, sunscreen is taken seriously, and for good reason. Many sunscreens designed primarily to protect your skin from UV radiation are regulated as therapeutic goods by the Therapeutic Goods Administration (TGA).
So, when you see that AUST L number, here’s what it actually tells you.
Most therapeutic sunscreens sold in Australia are included in the Australian Register of Therapeutic Goods (ARTG) as listed medicines.
If your sunscreen has an AUST L number, it means the product is listed on the ARTG and regulated by the TGA.
To list a therapeutic sunscreen, the product sponsor must certify that it meets the relevant Australian requirements around safety, quality and efficacy. This includes requirements around permitted ingredients, manufacturing, testing, labelling and the claims made about the sunscreen.
It’s a small number on the bottle, but it tells you your sunscreen sits within Australia’s regulatory framework for therapeutic sunscreens.
This is where things can get a little confusing.
TGA-listed and TGA-approved aren’t quite the same thing.
Listed therapeutic sunscreens aren't individually evaluated by the TGA before they reach the shelf. Instead, the sponsor legally certifies that the product meets the applicable requirements and holds the evidence needed to support its claims.
The TGA then monitors therapeutic sunscreens on the market and can conduct compliance reviews, laboratory testing or take regulatory action if an issue arises.
So rather than looking for the words “TGA approved”, look for the sunscreen’s AUST number.
Here's something many people don't realise: Australian sunscreen labels don't necessarily show every ingredient in the formula.
While active sunscreen ingredients must be declared, you may not see a complete ingredient list on the pack in the same way you would expect with many cosmetic products.
The good news is that you can find more information through the TGA's public ARTG database.
Simply search using the AUST L number printed on your sunscreen. This will bring up the product's ARTG entry, where you can view information about the ingredients included in the sunscreen.
At Wotnot, we believe you should be able to easily see what you're putting on your skin, which is why we choose to list our ingredients on our packaging.
That little AUST L number is only one part of choosing your sunscreen. Your label can tell you a lot about what you're putting on your skin.
Look for:
If you're looking for a mineral sunscreen, zinc oxide is an active UV-filtering ingredient you'll commonly see on the label.
At Wotnot, we use non-nano zinc oxide as the foundation of our Zinc Shield, providing broad-spectrum mineral protection designed to fit into everyday life.
Because for us, choosing sunscreen isn't only about the SPF number on the front. It's also about understanding what you're putting on your skin and finding a formula you'll genuinely want to use every day.
