What Is Galactomyces Ferment Filtrate?
Galactomyces Ferment Filtrate is a skin care ingredient derived from Galactomyces, a type of yeast first noticed by sake brewers who had remarkably soft youthful hands after years of working with fermented rice. Chemically, the filtrate is a blend of amino acids, vitamins, enzymes and skin friendly organic acids that remain after the yeast is fermented and then carefully filtered to remove solid residues. The process starts with cultivating Galactomyces in a nutrient rich solution, allowing it to ferment, then isolating the liquid portion that carries the active compounds. Thanks to its ability to attract and hold water this filtrate made its way from Japanese breweries into South Korean beauty labs in the early 2000s and is now a popular addition to essences, serums, lightweight moisturizers, sheet masks and anti aging lotions.
Galactomyces Ferment Filtrate’s Cosmetic Benefits/Uses
This ingredient is valued for how it improves skin hydration and overall texture.
As a humectant Galactomyces Ferment Filtrate draws moisture from the environment and binds it to the skin surface, helping formulas keep skin plump smooth and comfortable while reducing the appearance of fine lines caused by dehydration.
Who Can Use Galactomyces Ferment Filtrate
Galactomyces Ferment Filtrate is generally suitable for all skin types including dry, normal and combination skin thanks to its moisture binding nature. Oily and acne prone users often tolerate it well because it is lightweight and does not add occlusive oils, though very sensitive skin may prefer a low concentration formula until tolerance is clear.
The ingredient is produced from a yeast fermentation process with no animal derived inputs so it fits vegan and vegetarian lifestyles.
There is no evidence that Galactomyces Ferment Filtrate poses a specific risk to women who are pregnant or breastfeeding, yet this text is not medical advice and anyone expecting or nursing should confirm product choices with a healthcare professional.
The filtrate is not known to increase photosensitivity, so it will not make skin more reactive to sunlight. Standard daytime sun protection habits remain advisable when using any skincare routine.

Rating: 0/5
Galactomyces Ferment Filtrate is water based, contains no heavy oils or waxes and sinks in quickly, so it does not clog pores. That places it at the very bottom of the comedogenic scale.
Suitable for acne prone and breakout prone skin.
Because the filtrate is usually added in low to moderate amounts it rarely alters how pore clogging a final formula might be. Always look at the whole ingredient list if congestion is a concern.
