Created by Max Factor, SK-II represents a skin routine discovered, rather unusually, by a Japanese monk visiting a sake brewery where he noticed that the brewery workers had extraordinarily soft and youthful hands. A series of experiments by a team of skincare scientists attributed the secret to a clear, nutrient-rich liquid extracted during the yeast fermentation process. This liquid was named Pitera and now forms the basis of this precious skin care range, penetrating deeply into the dermis level, strengthening the skin structure and restraining the production of melanin for a clearer, youthful complexion.
