Brand cream SK-II is created using a unique formula that penetrates deep into the skin's surface.
Thanks to an exclusive ingredient PITERA™, as well as extracts of kinren and white peony, the product gently exfoliates the skin and acts as a ‘source of youth’, accelerating cell renewal and reducing visible signs of skin ageing accumulated over 10 years. 
What is PITERA™? PITERA™ is SK-II's patented natural bio-ingredient obtained through fermentation. It improves many aspects of visible skin damage and signs of ageing. The origin of PITERA™: In the 1970s, SK-II scientists noticed that the hands of elderly Japanese sake brewers looked significantly younger than their age. It turned out that their hands were in daily contact with fermented sake mash — this was the key to the discovery of PITERA™. After extensive research, a natural fermented yeast extract called PITERA™ was isolated, which has the ability to improve skin quality. What makes PITERA™ unique: It contains more than 50 micronutrients, including antioxidants, vitamins, minerals and amino acids, which nourish the skin, improve its texture and reduce visible damage.
