SK-II and PITERA SK-II transformed skincare when scientists discovered PITERA, the proprietary, natural bio-ingredient that forms the heart of all our products. We discovered PITERA during our tireless quest for beautiful bare skin. In the 1970s, our scientists became fixated on the soft, youthful-looking hands of elderly workers at a Japanese sake brewery. We knew the secret must lie in yeast and fermentation process.Rich in vitamins, amino acids, minerals and organic acids, SK-II’s proprietary ingredient PITERA, dramatically improves the natural surface rejuvenation process.
