What is Galactomyces Ferment Filtrate?

Galactomyces Ferment Filtrate, often shortened to GFF, is an ingredient made through the fermentation of a specific type of yeast. It was first noticed decades ago, when people observed that the hands of sake brewers, who are regularly exposed to fermenting rice and yeast, stayed remarkably smooth and youthful looking. That observation eventually led to it becoming a widely used skincare ingredient, sometimes sold under trademarked names like Pitera. GFF is included in INTOIT's IlluminEye Under Eye Serum, where it helps support the delicate skin around the eyes.

How Does It Work?

Galactomyces Ferment Filtrate works on skin in a few connected ways. It activates a receptor in skin cells, called the aryl hydrocarbon receptor, that switches on the skin's production of filaggrin, a protein that is one of the key natural building blocks behind skin's own moisture-holding ability. It also switches on a separate antioxidant pathway inside skin cells that helps protect against the everyday stress caused by sun exposure and pollution.

In published clinical trials, skincare formulas containing GFF have been shown to visibly reduce facial redness, roughness, and the look of enlarged pores after regular use. Because the under-eye area has thinner, more delicate skin, these barrier-supporting and calming effects are part of why GFF is a common choice for eye-area formulas.
