SK-II (‘ess-kay-two’) 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.
