About SK-II

For more than 40 years, SK-II has touched the lives of millions of women around the world through skin and life transformation. The fascinating story behind SK-II began with a quest to understand why elderly sake brewers had wrinkled faces, but extraordinarily soft and youthful-looking hands. These hands were in constant contact with the sake fermentation process. It took years of research for scientists to isolate the miracle ingredient PITERA™, a naturally-derived liquid from the yeast fermentation process. Since then, SK-II with PITERA™ has become a special secret shared by celebrities all over the world such as Tangwei, Haruka Ayase, MINA, Zhang Zi Feng, and Kaori Momoi.
