Physical sunscreens, such as zinc oxide, are usually thick white or colored cream. They prevent the skin from being exposed to the sun's ultraviolet rays. They are useful for high-risk areas such as the nose, lips, and shoulders. It's safest to keep babies younger than 6 months out of the sun. Use sunscreens on children older than 6 months.
