Untanned, no. Younger, yes. Nivea is really a product line. Most of their products are one of the thousands of products out there that purport to "reduce wrinkles and make you look 15/20/insert-X-number-of-years younger". Nivea also sells moisturising cremes, facial cleansers, and other similar assorted bath/beauty products, all with the same claim that they "make you look younger".
