Ultraviolet (UV) radiation among with infrared (IR) radiation and the visible region of the spectrum (VIS) are part of the electromagnetic radiation reaching the Earth's surface. In addition to positive effects (e.g., synthesis of vitamin D), UV radiation also has an adverse impact on the human body, such as cancerous proliferation. During evolution, human skin has developed various protecting mechanisms against UV (e.g., melanin pigment), but their capacity is limited (especially during intensive exposure to the sun). Therefore, this article aims to present, characterize, and classify (cosmetic) products that actively prevent the effects of UV radiation on human skin. This article also describes the necessary steps and basic principles for the proper application of these products.

Keywords: ultraviolet (UV) radiation, UV index, skin phototype, photoprotection, UV filters, cosmetics.
