Quick answer: For a child with eczema-prone skin, choose an SPF 50 or 50+, broad-spectrum, water-resistant sunscreen,¹ ideally fragrance-free and made for sensitive skin, and patch test it before using it all over.² Many families find mineral sunscreens (zinc oxide or titanium dioxide) gentler, but the best sunscreen is one your child tolerates and that you'll apply generously. Widespread sunscreen use isn't recommended for babies under six months.¹ Always use sunscreen alongside clothing, a hat and shade.
Sunscreen checklist for eczema-prone skin
| Look for | Why it matters |
|---|---|
| SPF 50 or 50+ | The level Cancer Council recommends |
| Broad-spectrum | Protects against both UVA and UVB rays |
| Water-resistant | Stays on better through swimming, sport and sweat |
| AUST L or AUST R number | Shows it's a TGA-regulated sunscreen tested to the Australian standard |
| Fragrance-free | Fragrance is a common irritant for sensitive skin |
| Made for sensitive skin, with a short ingredient list | Fewer potential irritants |
| Lotion or cream | Easier to apply evenly than aerosol sprays |
What does the AUST L number on sunscreen mean?
In Australia, most sunscreens are regulated as therapeutic goods by the Therapeutic Goods Administration (TGA). They must be listed on the Australian Register of Therapeutic Goods, and most carry an AUST L number on the label (some carry AUST R).³ SPF testing follows the Australian/New Zealand Sunscreen Standard, which the TGA updated to the 2021 edition in 2024.⁴
Look for the AUST L or AUST R number when you buy sunscreen, especially online or overseas. It's a quick way to check the product meets Australian requirements.
Mineral or chemical sunscreen: which is better for eczema?
There are two main types of UV filters:
- Mineral (physical) filters: zinc oxide and titanium dioxide, which sit on the skin's surface and reflect UV rays.
- Chemical (organic) filters: ingredients that absorb UV rays, such as octocrylene or avobenzone.
Both protect well when they meet the Australian standard. Some children with sensitive or eczema-prone skin tolerate mineral sunscreens better, and occasionally a chemical filter can cause irritation or an allergic reaction. Reactions vary from child to child, though, so the most important things are:
- choosing a sunscreen your child's skin tolerates,
- patch testing it first,
- applying enough, and reapplying regularly.
Ingredients to check on the label
- Fragrance or perfume: choose "fragrance-free" rather than "unscented", which can still contain masking fragrance.
- Essential oils and botanical extracts: these can irritate some sensitive skin, even when natural.
- Alcohol-based formulas: these can sting and dry eczema-prone skin.
If your child has a known allergy to an ingredient, such as from patch testing by a dermatologist, always check the full ingredient list.
How to patch test a new sunscreen
Cancer Council recommends testing a sunscreen on a small area of skin before using it all over.²
- Apply a small amount to a patch of unbroken skin, such as the inner arm.
- Leave it on, and repeat over a few days.
- Watch for redness, stinging, itching or a rash.
- If there's no reaction, you can use it more widely. If there is, wash it off, moisturise, and try a different product.
How to apply sunscreen on eczema-prone skin
- Moisturise first. Apply your child's moisturiser, such as Stelatopia+ Lipid-Replenishing Cream, and let it soak in for a few minutes.
- Apply sunscreen generously to all exposed skin, 15 to 20 minutes before going outside.⁵ Smooth it on gently rather than rubbing hard.
- Skip broken or weeping skin. Don't apply sunscreen to raw or weeping eczema; cover those areas with loose cotton clothing instead.
- Reapply every two hours,⁵ and after swimming, sweating or towel drying.
- Use prescribed creams as directed. If your child uses a prescribed treatment, apply it as your doctor advises and let it absorb before sunscreen. Ask your GP if you're unsure about timing.
Avoid aerosol sprays. The Royal Children's Hospital Melbourne notes that aerosol sunscreens are difficult to apply correctly to get enough protection.⁶
Sunscreen for babies with eczema
- Under six months: widespread use of sunscreen isn't generally recommended, as babies' skin is very sensitive.¹ Protect your baby with clothing, a hat and shade.
- Under 12 months: keep babies out of direct sun whenever the UV Index is 3 or above.¹
- Over six months: use an SPF 50 or 50+ sunscreen on skin that can't be covered, as the last line of defence after clothing, hats and shade.¹
Removing sunscreen at the end of the day
Wash sunscreen off in a lukewarm bath with a gentle, soap-free cleanser such as Stelatopia Cleansing Oil, which cleanses without stripping the skin's natural oils. Pat the skin dry and moisturise straight away. For step-by-step tips, read our guide on how to bathe a baby with eczema.
What if my child reacts to sunscreen?
Stop using the sunscreen, gently wash the area, and moisturise. Talk to your pharmacist or GP about alternatives. If reactions keep happening, a dermatologist can do patch testing to find which ingredient is causing them. In the meantime, rely on clothing, hats and shade.
Frequently asked questions about sunscreen and eczema
Is sunscreen safe for children with eczema?
Yes, for children over six months. Sun protection matters for all children, including those with eczema. Choose an SPF 50 or 50+, broad-spectrum sunscreen,¹ ideally fragrance-free, and patch test it first.²
Are kids' or baby sunscreens different?
They follow the same Australian standard and SPF rules, but they're often fragrance-free and formulated for sensitive skin. Check for SPF 50 or 50+, broad-spectrum protection and an AUST L or AUST R number.
Do spray sunscreens work for eczema-prone skin?
Lotions and creams are a better choice. Aerosol sunscreens are difficult to apply correctly,⁶ and some contain alcohol, which can sting eczema-prone skin.
Should I use sunscreen in winter?
Yes, whenever the UV Index is 3 or above. Check your local sun protection times, as UV levels can be high enough for sun protection even on cool or cloudy days in parts of Australia.
