What is sunscreen?

  • (noun): A cream spread on the skin; contains a chemical (as PABA) to filter out ultraviolet light and so protect from sunburn.
    Synonyms: sunblock, sun blocker


Sunscreen (also commonly known as sunblock, sun tan lotion, sun screen, sunburn cream or block out) is a lotion, spray, gel or other topical product that absorbs or reflects some of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn. Skin-lightening products have sunscreen to protect lightened skin because light skin is more susceptible to sun damage than darker skin. A number of sunscreens have tanning powder to help the skin to darken or tan; however, tanning powder does not provide protection from UV rays.
