When can babies wear sunscreen? From around 6 months, on small areas of exposed skin such as the face, backs of hands and feet, alongside shade, clothing and a hat. For babies under 6 months, Australian health guidance recommends shade, protective clothing and a broad-brim hat as the primary forms of sun protection rather than widespread sunscreen use.
General information only, based on publicly available guidance from Australian public health organisations. It is not medical advice. Every baby is different. Please speak with your GP or child and family health nurse for advice specific to your child.
Why the guidance is shade-first for young babies
Babies' skin is still developing, and physical protection (shade, clothing, broad-brim hats) is the most reliable form of sun protection at that age. Australian guidance simply prefers it.
The general recommendation is to keep babies under 12 months out of direct sun when the UV index is 3 or above. The SunSmart app shows sun protection times for your location each day and is the most practical tool for planning time outside.
You may notice that we never describe our sunscreen as suitable "from newborn". That is deliberate. Our positioning follows national guidance rather than stretching past it.
From around six months: introducing sunscreen gently
When you are ready to introduce sunscreen, take it slowly.
Start with a patch test: apply a small amount to your baby's inner arm and wait 24 to 48 hours. If there is no reaction, you can begin applying to small areas of exposed skin not covered by clothing (face, backs of hands, feet) with shade and clothing still doing most of the work.
Apply 15 to 20 minutes before heading outside. Reapply every 2 hours and after swimming or towelling.
What to look for in a baby sunscreen
Four markers should appear on every sunscreen you consider for a baby or young child.
SPF50+. The SPF number tells you how much UVB radiation the sunscreen filters, and SPF50+ is the standard to look for in Australian conditions.
Broad spectrum. This confirms UVA protection alongside UVB. Both matter.
Water resistant up to 4 hours. A sunscreen tested to maintain its SPF for that duration during water activity. Reapplication is still required.
TGA registration. Every sunscreen sold in Australia carries an AUST L number. Ours is AUST L 391791, and any listing is publicly searchable on the Australian Register of Therapeutic Goods at tga.gov.au.
Then the free-from list. Terms like "gentle" appear on almost everything; a named list is what is actually useful. For babies and sensitive skin, look for a sunscreen free from oxybenzone, homosalate, parabens, phthalates, sulphates, petroleum, triclosan, BPA, essential oils and fragrance. Fragrance-free should be the baseline, and it is worth confirming rather than assuming.
Our SPF50+ Sensitive Skin Sunscreen meets all of the above. It is TGA-registered (ARTG AUST L 391791), independently tested by Eurofins Dermatest to a mean SPF of 61.0 (ISO 24444 and AS/NZS 2604:2012), infused with Aloe Vera and Vitamin E, and gentle enough for babies, made for the whole family. The 30g travel size is an easy way to try it first.
How to apply sunscreen to a baby
Apply generously, 15 to 20 minutes before sun exposure. A thin layer delivers less protection than the SPF on the label indicates, because SPF testing is conducted at a standardised amount per area of skin. Generous application is correct, not overcautious.
Reapply every 2 hours and after swimming or towelling. No sunscreen, regardless of SPF or water resistance, stays fully effective indefinitely.
Sunscreen is one layer, not the complete answer. Protective clothing, a wide-brimmed hat and shade still matter, particularly during peak UV hours, typically 10am to 3pm in Australia.
The spots that get missed most often: ears (tops, backs and the outer rim), feet and the tops of toes, the back of the neck, and hands. Spending an extra few seconds on these spots, particularly for babies who are carried or in a pram facing up, makes a real difference.
Texture decides whether any of this happens. A sunscreen that feels heavy or leaves a chalky residue turns application into a standoff, and when application is a battle, reapplication stops. Ours is lightweight, fast-absorbing and non-greasy, with no white cast. Our guide to applying sunscreen to a wriggly baby or toddler has more.
The full sun protection picture for babies
Sun protection is more than sunscreen. For babies, a simple five-part habit covers the basics: shade, clothing, hat, sunscreen where skin is exposed, and timing outings outside peak UV windows.
- Choose lightweight long sleeves and full-coverage clothing for time in the sun.
- Use a hat that shades the face, neck and ears.
- Head to the shady side of the park.
- Check the SunSmart app and plan outings around sun protection times.
- Apply sunscreen to any skin left exposed.
Plan around sun protection times rather than avoiding the outdoors. Being outside is good for babies and carers.
FAQs
When can I put sunscreen on my baby?
From around 6 months, on small areas of exposed skin, after a patch test. Under 6 months, shade, clothing and a broad-brim hat come first.
Can I use sunscreen on my newborn?
For babies under 6 months, health experts recommend shade, protective clothing and a broad-brim hat as the primary forms of sun protection. If you have questions about what is right for your baby, speak with a GP or child and family health nurse.
Is SPF50+ too strong for a baby?
SPF measures protection level, not formulation harshness. A high SPF number does not make a sunscreen more intense or less gentle. Gentleness comes from what is in (and not in) the formula, not the SPF rating.
Can I use it on my baby's face?
Yes. The formula is designed for face and body use. Apply carefully around the eye area and avoid direct contact with eyes. If contact occurs, rinse gently with water.
Do babies need sunscreen on cloudy days?
Yes, on days with a UV index of 3 or above. UV radiation, not temperature or brightness, is what matters. Check the UV index with the SunSmart app before heading out.
What if my baby has a reaction to sunscreen?
Stop use and seek advice from a health professional.
