Babies should generally start wearing sunscreen at 6 months of age or older. For babies under 6 months, sunscreen is not recommended because their skin is much thinner, more sensitive, and can absorb the chemicals in sunscreen more easily, which increases the risk of irritation or allergic reactions. Instead, for infants younger than 6 months, protection from the sun should focus on keeping them in the shade, dressing them in protective clothing, and using wide-brimmed hats. When babies reach 6 months old, you can begin applying a broad-spectrum sunscreen with at least SPF 30. Mineral-based sunscreens containing zinc oxide or titanium dioxide are preferred because they are gentler on baby skin and act more as a physical barrier rather than being absorbed into the skin. Even after starting sunscreen, it is important to continue using other protective measures like shade, hats, protective clothing, and avoiding direct sun during peak hours (typically 10 AM to 4 PM). Sunscreen should be applied generously to all exposed areas and reapplied every two hours or more often if the baby is in water or sweating. Summary:
- Under 6 months: Avoid sunscreen; use shade, hats, and protective clothing.
- 6 months and older: Use broad-spectrum SPF 30+ sunscreen, preferably mineral-based.
- Use multiple layers of protection and avoid peak sun hours for all babies.
These recommendations come from health authorities including the FDA, American Academy of Pediatrics, and pediatric dermatologists.
