The fascinating story behind SK-II began at a sake brewery in Japan, where scientists noticed the elderly workers 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.
