Sunscreen is a substance used in lotions, gels, sprays to filter the sun's ultraviolet radiation on the skin. Sunscreen reduces the danger of sunburn but allows some rays to pass though by using different SPFs or Sun Protection Factor, the degree by which a sunscreen protects the skin. The higher the SPF number, the more the sunscreen will shield the skin from UV rays.
