No, NIVEA is not a Korean brand.
NIVEA is a brand of personal care products owned by Beiersdorf, a German company. Beiersdorf was founded in 1882 in Hamburg, Germany. The iconic NIVEA Creme was invented in 1911. The name "NIVEA" comes from the Latin word "niveus/nivea/niveum," meaning "snow-white." While NIVEA products are sold and enjoyed worldwide, including in South Korea, its origins and headquarters remain in Germany.
