6 Surprising Benefits of Galactomyces on Your Skin

Published July 7, 2020
Have you ever watched a Korean series and wondered: how do they get such smooth, pore-free skin?
Apparently, aside from genetics, Koreans have one more secret to their youthful glow: galactomyces.
What is galactomyces?
A by-product of sake fermentation, galactomyces is a type of fungus belonging to the Dipodascaceae family. Yes, you read it right: it’s a fungus. But before you get grossed out, remember that it’s a common ingredient in some of your favorite fermented foods and in many Korean skincare ingredients.
Besides, the substance that you put on your skin isn’t the fungus itself. Rather, it’s the fermentation filtrate, a filtered extract that is basically the yeast’s juice. The filtration process leaves it free of bacteria and other undesired materials. What remains is a nutrient-dense material that’s packed with amino acids, vitamins, and minerals.
According to legends, galactomyces was first discovered in a sake factory. Visitors noticed that the elderly workers have such smooth, wrinkle-free hands even as their faces look old. Years of research then ensued, and galactomyces was born.
All across Japan, Korea, and most of East Asia, galactomyces slowly gained a loyal following. Thanks to pop culture, that fanbase has now expanded to the rest of the world. It’s not only becoming one of the most popular skincare ingredients, but it has also become a staple in many anti-aging products around the world: serums, creams, facial wash – you name it.
But what makes galactomyces so popular? Simple, because it works. Here are six ways your skin can benefit from galactomyces:
1. It Takes Years Off Your Face
The legend of how the galactomyces was discovered might not be that accurate. But it has some grain of truth to it. Constant exposure to galactomyces can smooth out wrinkles, fine lines, and other signs of aging. As a result, your skin will look much younger for longer.
2. It Shrinks Pores
A study published in the Korean Journal of Aesthetic Cosmetology explored the skin benefits of galactomyces. Twenty volunteers were treated with essence containing 97% of galactomyces ferment. Results showed that the number of large open pores and blackheads were reduced by 15.66% to 21.84%.

3. It Reduces Oiliness
Our skin naturally secretes oil (sebum). In small quantities, they are beneficial. But if your skin produces too much oil, it can lead to several skin problems.
In the study cited above, the participants also reported reduced oiliness. Researchers observed that sebum production is dramatically reduced by 64.17%. This, in turn, improved the overall condition of the skin.
4. It Lightens Dark Spots
According to a 2014 study, they found that a facial treatment essence infused with 10% galactomyces can help brighten the skin. It shows that galactomyces can help reduce the appearance of dark spots by up to 60% in just 12 days. Results also suggest that it can decrease melanin production by up to 55%.
5. It Protects Your Skin and Keeps It Hydrated
A study in Japan found that galactomyces helps strengthen the skin’s barrier. This, in turn, protects it from harmful toxins in the environment. The improved barrier also keeps your skin’s moisture from seeping out keeping it constantly hydrated.
6. It Minimizes Acne Breakouts
With much smaller pores and reduced sebum production, the risk of acne and pimples are minimized.
Plus, a 2006 study revealed that yeast extracts have anti-inflammatory properties. This means that galactomyces is not only good at preventing acne. It can also treat acne breakouts.
The study’s result also showed that galactomyces can protect damaged tissues. So aside from reducing the redness and swelling, it also allows your skin to recover after a bout with acne.
