The Benefits of using Fermented Ingredients in Korean Skincare

Discover The Magic World of Fermented Skincare

Korea- the land of skincare, K-Pop and Kimchi. Kimchi is a fermented cabbage dish that is served with almost every meal in Korea. It has been in the news internationally for a good chunk of the last decade for its numerous health benefits and unique taste. Just like Kimchi, Korea also specialises in something which may seem odd and new- fermented skincare.

What is fermentation? 

The process of fermentation is used in creating food and beverages like wine. It transforms sugars into bacteria, yeasts or other microorganisms. This process produces a more precise and purer ingredient, without the presence of undesirable byproducts. With newer technology, the benefits of fermentation are thriving in safe and effective lab environments. 

How does it relate to skincare?

When it comes to skin and skincare benefits, fermentation breaks down natural molecules and makes them smaller so it’s easier for them to be absorbed deeper into your skin’s surface. These smaller molecules become more potent and precise so they can penetrate the skin deeper and for optimal absorption. Korea really knows what they are doing when it comes to skincare trends!

Products that are labelled as “fermented skincare” often contain either plant ingredients plus yeast or beneficial bacteria to break sugars down into acids, probiotics, and postbiotics.

Why is fermented skincare good for us?

Fermented ingredients have just as many perks for your skin as they do for your gut. Some of the benefits are as follows:

  • It has anti-inflammatory properties.
  • It helps balance the skin's pH value.
  • It helps strengthen the skin's barrier.
  • It creates a smoothing effect on the skin.


Additionally,  the fermentation process creates new amino acids, organic acids, and antioxidants that didn’t originally exist in the raw material. This leads to the most optimal formulation that will be a great addition for your overall skin health.

There are a few ingredients in particular that especially benefit from fermentation. Hyaluronic acid  is a staple in Korean skincare and now in Western skincare as well. Many types of hyaluronic acid have larger molecules that are unable  to penetrate the skin's surface and just sit on top of the skin. By using the process of fermentation, the new and improved hyaluronic acid is able to penetrate the skin’s surface 10 times more than the regular kind.

Another example of when fermentation can be beneficial is in regards to collagen. Typically, the collagen molecule is too large to penetrate the skin's surface. However, fermented collagen replenishes up to two times more than normal collagen, leaving you with noticeably firmer skin for the diminished appearance of fine lines and wrinkles.

The skincare benefits are endless!

Which skin type can use fermented skincare?

Some natural raw ingredients contain toxic substances like heavy metals and pesticides that may cause irritation and inflammation to the skin. The fermentation process neutralises these toxic substances, making the product safer for even sensitive skin types.

Fermented skincare is also known as the “All-in-one anti-ageing product” as it is loaded with natural antioxidants, amino acids and vitamins. Thus, it is an excellent ingredient to include if one of your skin concerns are fine lines and wrinkles.


Recommendations for fermented skincare products are:


Galactomyces is a fungus that helps reduce blackheads, sebum, dead skin and acne. In addition, it minimises the appearance of pores and brightens skin tone. It is usually found used while fermenting rice, sake or wine.

An interesting story about how Galactomyces came to be such a coveted skincare ingredient is that- in the 1970s, scientists discovered how even the most aged brewers in a Japanese sake factory had youthful hands as compared to their faces. They concluded that it was the yeast (Galactomyces) used to make sake that was in constant contact with their hands, that led to this phenomena. 

The One Thing Galactomyces Ferment Filtrate is a light toner which is rich in yeast peptides, amino acids, proteins and Vitamin B1 and B2. These ingredients help strengthen the skin barrier and gives you a dewy and glowing complexion. It also helps in hydrating the skin while removing dead skin cells and minimising the appearance of pores.

The One Thing Galactomyces Ferment Filtrate can be used in multiple ways- either by itself or mixed in other products. It is a great product if you want to reap the full skincare benefits of fermented products.
