What Is Galactomyces And Why Does Skin Love It?

It’s the star ingredient in many Asian beauty products, touted for its ability to do everything from balancing uneven skin tone to fighting bacteria.

But what is galactomyces and why does skin love it? We’re putting it under the microscope to see how it works and who should be using it.


What Is Galactomyces?

Galactomyces is a type of yeast, a byproduct of the sake fermentation process. If you buy into the marketing hype, legend has it that the effects of galactomyces were first discovered by sake brewers, who noticed that their hands stayed young even though the rest of their bodies aged. Galactomyces was supposedly the secret ingredient behind their younger, smoother, brighter hands.

In skincare products, galactomyces has the ability to increase product absorption and also has known antioxidant effects. It has been shown to improve sebum levels in oily skin, as well as brighten and tackle acne. Studies have also show that galactomyce causes epidermal cells to produce hyaluronic acid. This means it has great moisturising properties.
