Galactomyces Ferment Filtrate

Also-called-like-this: Pitera
What-it-does: moisturizer/humectant


A famous water-like, yeast-derived ingredient that the whole SKII brand is built on. As legend has it, SKII scientists in the 1970's discovered by chance that aged Japanese sake brewers have amazingly soft and youthful hands in contrast to their aged and wrinkled faces. They concluded that the secret must lie in the yeast that the brewers’ hands were in constant contact with during the sake fermentation process. 

So Pitera - obtained by a fermentation process of a certain yeast belonging to the genus Galactomyces -  was discovered as an anti-aging, skin-nourishing magic liquidThe company claims that the clear, water-like liquid is loaded with good-for-the-skin stuff and is rich in vitamins, amino acids, minerals and organic acids.  

As for the science behind Pitera, SKII parent company P&G did an in-vitro (made in the lab) study that confirmed that Pitera-containing moisturizers do indeed help to protect the skin against damage. More specifically, they found that Pitera has antioxidant effects and increases hyaluronan production in epidermal cells. And more hyaluronic acid in the skin means better hydrated, plumper, healthier skin.

If that would not be enough, there is also a 2014 study showing that Pitera might be able to help with skin pigmentation and a 2015 study finding that Galactomyces Ferment Filtrate can activate aryl hydrocarbon receptor (AhR) that's important in epidermal homeostasis by upregulating epidermal barrier proteins. English translation equals: Pitera might be able to help with a healthy skin barrier

All in all, both anecdotal and scientific evidence show that Pitera is a skin goodie so if you are into essences and yeast-derived fermentations, it's definitely worth a try.
