The Innovation Eucerin Skin Research has developed a comprehensive protection against sun damages in addition to effective UVA/UVB protection, the natural antioxidant Licochalcone A is proven to help protect the skin cells in the deeper epidermal skin layer and Glycyrrhetinic Acid helps support skins own repair mechanism. Licochalcone A (Glycyrrhiza Inflata extract) Licochalcone A is a natural ingredient from the roots of Glycyrrhiza Inflata. Due to its natural habitat this plant has developed its own protection mechanism against UV radiation. UV radiation stimulates the enzyme production which is involved in release of this active ingredient. The antioxidative efficacy protects the plant cells against free radicals induced by UV radiation and is now used as a highly effective active to help protect cells in the deeper layer of the skin.
