In the 1970s, SK-II scientists began a fervent quest to uncover a skincare ingredient that would make beautiful skin a reality for every woman.

Across land and sea, they sought for the answer. Despite researching a myriad of possibilities, the secret they were looking for long eluded them.

It was only by happenstance that the scientists eventually found themselves in a simple sake brewery where they chanced upon the soft and youthful hands of aged sake brewers. The breath-taking sight was the inspiration of the skincare miracle they would eventually uncover – a destiny of beauty was finally within reach.


The astounding sight of the aged sake brewers’ wrinkled faces 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 fermentation liquid that the brewers’ hands were in constant contact with during the sake fermentation process.

A rigorous search of over 350 kinds of yeast was conducted before our researchers discovered the unique yeast strain that held the secret to crystal clear skin.

It was the birth of the secret that would soon become known as Pitera™. The quest to find the secret ingredient was finally over but another journey was about to begin – the discovery was merely the dawn of a beauty revolution to come.

Derived from a strictly controlled natural fermentation process, Pitera™ is a clear liquid rich in vitamins, amino acids, minerals and organic acids. This fascinating combination of nutrients work to dramatically improve the skin’s natural surface rejuvenation process.

A unique and signature ingredient, Pitera™ bears close resemblance to the skin’s Natural Moisturizing Factors (NMF) – a deciding element in the maintenance and enhancement of the skin’s 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™
