What it is: An essence that works on multiple skin concerns and types to help transform your complexion into a crystal-clear one.What it does: This formula moisturizes skin while helping to soften and smooth texture, reduce dark spots and fine lines due to dryness, enhance radiance and even the look of skin tone. The lightweight liquid is quickly absorbed into skin, and contains 90% Pitera. Pitera is a natural bio-ingredient derived from yeast fermentation that resembles your skin's natural moisturizing factors. It contains over 50 micronutrients like vitamins, minerals, amino acids and organic acids to condition skin. This iconic essence has remained essentially unchanged for almost 40 years, which has allowed SK-II to witness Pitera's powerful effect on skin's appearance over time. How to use: Use twice daily after cleansing and toning and directly before applying your moisturizer. Pour about 2–3 shakes into your hand, press your palms together then pat the essence all over your face.
