    topical product protecting skin from harmful ultraviolet radiation

    Sunscreen, also known as sunblock or sun cream, is a topical product designed to protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun. It contains active ingredients that either absorb, reflect, or scatter UV rays, thereby reducing the risk of sunburn, premature aging, and skin cancer. The effectiveness of sunscreen is often indicated by its Sun Protection Factor (SPF) rating, which measures the level of protection against UVB rays.
