Each bottle contains 90% PITERA™ and since it’s observed to resemble your own skin’s Natural Moisturizing Factors (NMF), skin recognizes PITERA™ as its own, allows it all in and lets it work its magic in its pure active form.This iconic essence’s formula has remained essentially unchanged for almost 40 years, uniquely allowing us to witness PITERA™‘s powerful effect on skin appearance over time (in days, years, and decades) for millions of women around the world.What else you need to knowOur story begins with a chance observation at a sake brewery in Japan, where a group of scientists noticed the elderly brewers had wrinkled faces but extraordinarily soft and youthful-looking hands.Intensive search 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 an exclusive yeast strain under the most stringent conditions that remain SK-II’s most valuable trade secret to this day.A miracle like no other, PITERA™ is pure power of nature harnessed by advanced technology.Active Ingredients: PITERA™ - natural bio ingredient derived from yeast fermentation that resembles your skin's Natural Moisturizing Factors; contains over 50 micro-nutrients like vitamins, minerals, amino acids and organic acids to condition skin's natural functions.Galactomyces Ferment Filtrate*, Butylene Glycol, Pentylene Glycol, Water, Sodium Benzoate, Methylparaben, Sorbic Acid. *PITERA™Suggested Use: Application is simple.
