Creation of SK II products were inspired by the smooth and youthful hands of the elderly ladies at a sake brewery in Japan. They realized that it was due to their constant contact with the sake fermentation process. The scientists extracted the miracle ingredient, Pitera, from the yeast fermentation process. SK-II products contain Pitera, vitamins, amino acids, proteins and organic acids to help enhance skin surface renewal process. This Japanese skin care brand is most famous for SK-II Facial Treatment Essence which is sometimes referred as "miracle water."
