SKII was launched in Japan in 1980 with its revolutionary Pitera ingredient at the heart of its products. Scientists observed how aged sake brewers retained youthful looking hands after years of submerging their hands in fermented yeast. After much research and development, the particular strain of naturally-occurring yeast was isolated for use into what has evolved into Pitera. Now you can buy SKII beauty and skincare products online and direct from Japan with ShopJBP.
