There are three types of radiation: UVA, UVB, UVC. Long UVA rays, whose scope is 315-380 nm, present in sunlight and solariums not cause reactions in the skin, but much damage elastic fibers and collagen. Like the infrared rays destroy the capillaries and cause abnormal blood supply to the skin. As a result, skin becomes less well nourished and is aging much faster. UVB rays are the shorter-range 280-315 nm taken up by cells of the epidermis. Cause severe erythema and burns. Play a decisive role in lesion formation and skin cancers. Some of them penetrates the dermis damaging the elastic fibers. Tan skin, but also contribute to the formation of spots . UVC rays have a range of 100-280 nm and the highest energy. Almost completely absorbed by the ozone layer. If, however, reach the skin that are absorbed mostly by the stratum corneum. We are all constantly exposed to the adverse effects the sun so we must, if possible safely enjoy its advantages. Therefore, creams created with a filter.
