A powerful treatment to visibly soften texture, reduce the appearance of dark spots and fine lines due to dryness, even the look of skin's tone, and enhance visible radiance. PITERA™ Contains over 50 micronutrients like vitamins, minerals, amino acids, and natural acids to condition skin. The story begins with a chance observation at a sake brewery in Japan where scientists noticed the elderly brewers had wrinkled faces but extraordinarily youthful-looking hands. Intensive searches began out of millions of yeast strains and studies were conducted on hundreds of fermentation conditions. Now every drop of PITERA™ is produced by cultivating the one exclusive yeast strain under the most stringent conditions that remain SK-II's most valuable trade secret. This iconic essence's formula has then remained essentially unchanged for almost 40 years as the full efficacies of PITERA™ have not yet been uncovered; and until now, SK-II is continuing to discover new things it can do. A miracle like no other, PITERA™ is pure power of nature harnessed by advanced technology.
