A frequently asked question by young mothers is whether sunscreens are safe for babies and young children, and if so, which ones should they use. Dr. Julianne Mann, a pediatric dermatologist at Oregon Health Science University suggests the following:
"I recommend physical (non-chemical) sunscreens only for infants and babies less than two years old. I think we really don't have convincing safety data for long term use of chemical sunscreens in this age group, so I err on the side of safety and recommend zinc oxide or titanium dioxide-based sunscreens. Parents often ask me whether micronized zinc/titanium sunscreens are safe. I think they probably are, but again we don't have data so I suggest using non-micronized sunscreens since babies don't care if their skin looks a little white :-)
