A powerful treatment essence dubbed “Miracle Water” in Asia. Each bottle contains 90% PITERA™, a natural bio ingredient cultured exclusively in Japan for SK-II. Its transformative powers on skin appearance are legendary, that a bottle is sold every 2 seconds. What is it good for? Works on multiple skin concerns and skin types to transform skin to Crystal Clear Skin. It is the ONE almighty product you need to moisturize, soften and smoothen texture, reduce appearance of dark spots and fine lines due to dryness, enhance radiance, even the look of skin tone, make skin less oily looking and... the list goes on! In fact, the full efficacies of PITERA™ have not yet been uncovered and until now we continue to discover new things it can do. Why it Works Our formulation is a lightweight liquid that is quickly absorbed into skin unlike other thicker serums and essences. 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 know Our 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.
