Sun plays a major role in skin aging. Experts estimate that up to 80 percent of all visible skin aging processes are the result of too much UV radiation without adequate protection. This leads to an increased formation of free radicals and an excess of UV rays overwhelms the body's own protective system. The SUN High UV Protection Cream SPF 50 offers perfect protection against UVA and UVB rays as well as free radicals and thus prevents premature skin aging caused by light.
