Galactomyces Ferment Filtrate description

_Galactomyces_ ferment filtrate is a type of nutrient-dense yeast that is a byproduct of the fermentation of Japanese rice wine, or sake. Used widely in Japanese and Korean beauty products, its major selling point is that it can reduce the appearance of discolorations. Research bears out this claim: studies have found that _Galactomyces_ ferment filtrate can inhibit factors that lead to hyperpigmentation. Studies also show this yeast has potent antioxidant abilities to combat the impact of oxidative stress and helps soothe skin prone to sensitivity and redness. The independent Cosmetic Ingredient Review panel issued a tentative report on a series of yeast derived ingredients, including _Galactomyces_ ferment filtrate, for public comment on January 10, 2024. This preliminary report indicates _Galactomyces_ ferment filtrate is safe as used in cosmetics. Use levels of this ferment range from 10–100%. This seems high, but keep in mind most of the ferment is water. In fact, _Galctomyces_ ferment is suggested for use to replace water in cosmetics.
