Sunlight is undoubtedly one of the main reasons of premature aging of the skin. UVB rays as well as UVA rays cause skin damage; therefore, suntan products should contain both UVB and UVA filters and pigments providing high sunray protection. Modern suntan preparations offer the appropriate base for every skin type. Loss of hydration has to be offset. As a consequence, cosmetical suntan lotions not only protect against sunrays, but also must moisturize the skin and care for it.
