For babies under 6 months, the best protection from UV rays is to avoid direct sun exposure and use protective measures such as clothing and shade, with sunscreen being used only when necessary and in limited amounts, ideally with a high SPF like SPF 100+, as shown in a study published in the Journal of the American Academy of Dermatology 1. To protect babies under 6 months from UV rays, it is essential to:
- Keep them in the shade, especially during peak sun hours (10 am to 4 pm)
- Dress them in lightweight, long-sleeved shirts, pants, and a wide-brimmed hat that shades the face, neck, and ears
- Use stroller canopies or umbrellas for additional shade While sunscreen is generally not recommended for babies under 6 months due to their sensitive skin and potential for chemical absorption, the American Academy of Pediatrics advises that small amounts of sunscreen (minimum SPF 30) can be applied to limited areas like the face and backs of hands when adequate clothing and shade aren't available. However, a more recent study published in Experimental Dermatology 2 suggests that SPF 100 provides significant additional protection against mutagenic DNA damage and functional impairment of the cutaneous immunosurveillance, which may be beneficial for vulnerable populations, including babies. Therefore, if sunscreen must be used, choosing a mineral-based sunscreen with zinc oxide or titanium dioxide and a high SPF like SPF 100+ may be a better option, as they are less likely to irritate sensitive skin and provide better protection against UV rays. Babies' skin is thinner and more vulnerable to sun damage than adult skin, and sun damage during childhood increases the risk of skin problems later in life, making protection especially important.
