Physical sunscreens or sunblocks, such as zinc oxide, are usually
thick white or colored cream. Sunblocks have an
SPF of 15 or higher and 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.
