Sunscreen is a product that utilizes and combines sun protecting ingredients in order to protect the human skin from the dangerous [[ultraviolet rays]]. All sunscreens are different and vary in their level of protection from the powerful [[UVA]] and [[UVB]] rays. The sunscreen absorbs the sun’s rays, preventing them from reaching the skin. There is a difference between a chemical sunscreen and a physical sunblock. Sunscreen absorbs the rays, while sunblock reflects them. This product protects the human skin from skin cancer and includes many benefits. Sunscreen’s effectiveness is measured by a system called SPF, or the Sun Protecting Factor. Fifteen SPF protects against 94 percent of the sun’s rays and thirty SPF protects against about 96 percent of the sun’s rays.<ref>Unknown, Author.
