In the 1970s, SK-II scientists began a fervent quest to uncover a skincare ingredient that would make beautiful skin a reality. Across land and sea, they sought for the answer. Researching a myriad of possibilities ranging from Chinese herbs to hot spring water – the secret they were looking for eluded them for a long time. It was only by a chance encounter that the scientists observed the soft and youthful hands of aged sake brewers. The breath-taking sight was what hinted at the skincare miracle they would eventually uncover. A destiny of beauty was finally within reach.

The astounding sight of the wrinkled faces of aged sake brewers contrasting their soft youthful hands remained seared in the memories of the SK-II scientists. Back in the confines of the laboratory, they surmised that the secret must lie in the yeast that the brewers’ hands were in constant contact with during the sake fermentation process. And that is how an exhaustive research of over 350 yeast strains began. Poring over even the smallest singular detail, the scientists spent over a decade to isolate the single yeast strain that held the secret to crystal clear skin. It was the birth of a miracle, a beauty revolution that would soon come to be known as Pitera™.


Pitera™ is full of vitamins, amino acids, minerals and organic acids that work together to allow the skin’s natural surface rejuvenation process to function at its prime.

Derived from a strictly controlled natural fermentation process, Pitera™ is a clear liquid rich in vitamins, amino acids, minerals and organic acids. The fascinating combination of nutrients work to dramatically improve the skin’s natural surface rejuvenation process. This unique and signature ingredient bears close resemblance to the skin’s Natural Moisturizing Factors (NMF) – a deciding element in the restoration and enhancement of translucency, softness and smoothness. Nature, technology and craftsmanship blend harmoniously to create the miracle of Pitera™ — to present a promise of crystal clear skin that is yours to always keep.


I was on the research team that first discovered Pitera™. Even back then in 1980,
we knew we had found something very special – a gift of nature that will transform skin
for generations to come. Even today, we are constantly making new discoveries
about its efficacy after 30 years. — Takashi Yoshii, leading scientist who discovered Pitera™
