Sunscreen (also known as sunblock, suntan lotion, or sun cream in the United Kingdom) is a lotion, spray or other topical product that helps protect the skin from the sun's ultraviolet (UV) radiation. It reduces sunburn and other skin damage, with the goal lowering your risk of skin cancer. However, in the United States, the term suntan lotion usually means the opposite of sunscreen, and instead refers to lotion designed to moisturize and maximize UV exposure and tanning rather than block it. These are commonly called indoor tanning lotions when designed for use with tanning beds or just suntan lotion if designed for outdoor use and may or may not have SPF protection in them.
