What sunscreen is safe for a baby under six months?

Sunscreen is generally not recommended for babies under 6 months. Canadian and international guidelines say the best protection is shade, protective clothing, and a hat — sunscreen should only be used on small exposed areas (like the face or hands) when shade and clothing aren't enough, and Health Canada advises checking with your doctor first.

If sunscreen is needed on a young infant, mineral-based products with zinc oxide or titanium dioxide are preferred over chemical or spray sunscreens.

Strength of evidence

Good

This guidance comes from consistent recommendations by multiple national pediatric and health authorities (Canada, US, UK, Australia), not from randomized trials, since testing sunscreen on infants under 6 months raises ethical concerns.

What the evidence says

The Canadian Paediatric Society and Health Canada advise against using sunscreen on babies younger than 6 months, mainly because infants can rub it into their eyes or mouth, and their skin is more sensitive. Health Canada suggests checking with your health care provider before using any sunscreen on a baby this young. The main strategy for this age group is avoidance: keep your baby out of direct sun, use shade (umbrella, stroller canopy, trees), and dress them in lightweight, tightly-woven clothing and a brimmed hat.

If shade and clothing aren't enough to cover exposed skin, US and UK guidance (AAP/HealthyChildren, NHS) say it's reasonable to apply a small amount of sunscreen to exposed areas like the face and hands, even under 6 months. When sunscreen is used at this age, mineral-based (zinc oxide or titanium dioxide) formulas are generally preferred because they're less likely to irritate sensitive baby skin, and lotions or sticks are preferred over sprays, which can contain propellants and are easy for a baby to inhale.

For babies 6 months and older, all sources agree: use a broad-spectrum sunscreen with SPF 30 or higher, reapply every 2 hours (or after swimming/sweating), and combine it with shade and protective clothing rather than relying on sunscreen alone.

Bottom line: shade and clothing are the first line of defense for babies under 6 months. If you feel sunscreen is necessary, use a mineral-based one on small exposed areas and check with your pediatrician, especially before extended sun exposure.
