Famous in Japanese and Korean skincare, Galactomyces Ferment Filtrate is a nutrient-rich yeast-derived ferment known for its remarkable ability to enhance skin texture and tone. Its discovery dates back to 1970s Japan, where researchers observed that elderly sake brewers had unusually smooth, youthful-looking hands. Further analysis of fermented sake revealed the presence of Galactomyces, a beneficial ferment originating from the fungi genus.

This powerhouse ingredient is widely praised for its ability to reduce melanin production, making it effective in brightening dull skin, fading dark spots, and improving hyperpigmentation. Galactomyces also helps to strengthen the skin barrier by promoting keratinocyte differentiation and activating the aryl hydrocarbon receptor (AhR) key actions that improve moisture retention and protect the skin from UV damage and water loss.

In addition, Galactomyces is proven to be effective in minimizing enlarged pores, reducing blackheads, and controlling excess sebum. A Korean study showed that regular use of an essence containing Galactomyces significantly decreased open pores, helping to manage acne-prone skin and promote a smoother, more refined complexion.
