SK-II was born in the 1970s when SK-II scientists were on a quest to uncover a skin care ingredient that would actually make beautiful skin a reality. Inspired by the unaged and youthful-looking hands of elderly sake brewers, the team of scientists researched more than 350 strains of yeast to discover why the sake fermentation process kept the Brewers’ hands looking so young. During this process, Pitera was discovered as an effective anti-aging component. Since Pitera was discovered, it has been a key ingredient in SK-II skin care along with organic amino acids, minerals, vitamins, proteins, and saccharides.
