Galactomyces is a genus of fungi in the family Dipodascaceae.

Galactomyces Ferment Filtrate “is a nutrient dense yeast, and a byproduct of fermented sake”. (Wikipedia)

According to common legend, benefits of galactomyces were discovered  by accident in Japan in a sake brewery.  Visitors noted that the elderly brewers’ hands were smooth and wrinkle-free while their faces were old and worn out.   This observation led to numerous researches.  Eventually researches were able to pinpoint Aspergillus Oryzae – a fungus used in Japan to ferment different types of foods.  That fungus was responsible for young looking skin – it dramatically delays signs of aging. And this is how fungi and yeast made their way into skin are.

Later researches discovered galactomyces which is a major ingredient in today’s cosmetics.

What does Galactomyces do for skin?

“In cosmetics it’s used as a moisturizing agent and has antioxidant effects.  It improves the skin’s moisture barrier, helping to protect the skin from environmental stresses”. (Wikipedia)

In the year 2014 Asian Journal of Beauty and Cosmetology submitted a study which involved 20 volunteers.    Participants used the essence containing 97% of galactomyces ferment filtrate on their faces three times a day.

At the end of the study  participating volunteers’ skin was compared to those in control group.  Researchers noticed that the number of enlarged pores in participants using galactomyces reduced by almost 22%.   Amount of blackheads, sebum and keratin in faces decreased by 64 %.   Volunteers who used the essence had brighter skin and reduced number of comedones.

  • Shrink pore size
