Physical sunscreen to prevent sunburn

Physical sunscreens or sunblocks, such as zinc oxide, are usually thick white or colored cream. Sunblocks have an SPF of 12 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 and may be used on babies, though babies under 6 months old should be kept out of the sun.
