What sunscreen is safe for kids?

What the evidence says

For babies under 6 months, Canadian advice is to rely mainly on shade, hats and clothing rather than sunscreen. Caring for Kids (Canadian Paediatric Society) and HealthLink BC note that sunscreen isn't generally recommended at this age because babies can rub it into their eyes and mouth. Health Canada and the Canadian Dermatology Association add that if a baby must be in the sun, a small amount can be applied to uncovered areas like the face and hands, and it's reasonable to check with your health care provider first.

For babies over 6 months and older children, Canadian sources agree: use a broad-spectrum sunscreen (protects against both UVA and UVB) with an SPF of 30 or higher, reapplied roughly every 2 hours and after swimming or sweating. Look for products carrying the Canadian Dermatology Association logo, which means they've been specifically tested. On ingredients: Health Canada regulates all sunscreens sold here as non-prescription drugs or natural health products, and every approved product must show a DIN or NPN on the label.

When Health Canada tested a batch of sunscreens marketed for children, it did not find serious quality problems and confirmed none contained certain preservatives known to trigger skin reactions. A CMAJ review notes that a small FDA-sponsored trial found some chemical filters (like oxybenzone) can be absorbed into the bloodstream with heavy, repeated use, though the health significance of this is still uncertain; mineral sunscreens with zinc oxide or titanium dioxide avoid this issue and are often recommended for sensitive or reactive skin. Bottom line: shade and clothing come first for very young babies; broad-spectrum SPF 30+ sunscreen, ideally CDA-approved, is the standard safe choice from 6 months on, with mineral formulas as a good option for sensitive skin.
