In the 1970s, SK-II scientists were on a quest to uncover a skincare ingredient that would make beautiful skin a reality. They researched a myriad of possibilities ranging from Chinese herbs to hot spring water – but the secret they were looking for eluded them for a long time. It wasn't until they observed the contrast between the soft and youthful hands and the aged and wrinkled faces of sake brewers that they finally found what they were looking for: PITERA Essence. A single yeast strain that, during the sakes’ fermentation process, kept the brewers’ hands soft, supple and flawless even as they continued to age. This discovery was a game-changer in the skincare industry, and it's still revered today as one of the best ingredients for achieving beautiful, healthy skin.
