How a Natural Process Can Exponentially Enhance the Results of Your K Beauty Routine. 

For centuries, Eastern cultures have employed fermented ingredients as a natural remedy in cosmetics capable of combating a multitude of issues, most notably skin care and health.

In this post we will shed light on what fermentation actually is in cosmetics and how this technique as old as mankind, adopted in the production of food and beverages is simply fantastic when it comes to amplifying the natural power of ingredients and taking care of skin of any kind. 

After a definition of the fermentation process and the benefits when it is applied to cosmetic ingredients, we will go on to examine the benefits of the main fermented ingredients in Korean cosmetics. 


  • What Does Fermentation of Ingredients in Korean Cosmetics Consist of? Is it Like Bread, Pizza and Wine?
  • Is it True That Fermentation of Ingredients Makes Cosmetics More Effective? Why?
  • What are the Main Skin Benefits Given by Using Cosmetics Made from Fermented Ingredients?
  • What Are Some of the Main Fermented or Fermentation-Aiding Ingredients in Korean Cosmetics and Their Benefits for Skin? 

In What Does Fermentation of Ingredients in Korean Cosmetics Consist? Is it Like Bread, Pizza and Wine?

Let’s start by saying that fermentation is a totally natural process. To be clear: that of fermenting the ingredients in Korean (and other) cosmetics is exactly the same process that humans have been using since the dawn of time to produce food, drink, and drugs.

If we were to define fermentation, we would have to say that it is a process of transformation of organic substances in the absence of oxygen by some microorganisms. 

The process, which we repeat, occurs in nature in a completely natural way, can be replicated artificially by introducing certain microorganisms into a special vessel designed for the transformation of organic substances in an oxygen-free environment, which is called a fermenter. 

Is It True That Fermentation of Ingredients Makes Cosmetics More Effective? Why?

As we mentioned earlier, fermentation is a natural metabolic process, but what you may not know is that it transforms and enhances the properties of natural ingredients. 

In fact, compounds are broken down by the action of microorganisms such as bacteria and yeasts, which break down the matter that makes up the ingredients into even simpler and smaller parts. 

This processing done by microorganisms is something we might liken to a semi-chewing that makes organic molecules smaller and purer. 

In this way the molecules of the actives become more effective because they are more compact; their smaller size makes them easier to penetrate and be assimilated from deep within the skin. 

Also often through this miraculous process, it is possible to increase the concentrations of vitamins, amino acids, peptides and antioxidants of the original ingredients.

In this way, the substances produced by the fermentation process have an even more positive effect on the skin than the same unfermented ingredients because of the higher concentration of active ingredients operated by fermentation, which increases their antioxidant, nourishing and protective properties.

So: cosmetics made from fermented ingredients are more effective than those made from the same unfermented ingredients.

Is it true that Fermentation Enhances the Characteristics of Korean Cosmetic Ingredients in a Unique Manner Achieving Results Hardly Achievable in the Laboratory?

K beauty has always used fermentation, so much so that it has become its trademark. But why do cosmetics made from natural ingredients have a richness that is hard to match?

Fermentation produces more effective cosmetics.

As we saw in the previous section, many botanical ingredients are only available through this process because it increases their ability to first come into action (bioavailability) and improves their absorption by the skin.

Let’s take an example. As you may know, essential fatty acids help fight free radicals that cause premature aging and many other skin problems. Biofermentation of ingredients such as herbs, flowers, or oils improves the essential fatty acid content exponentially. Take for example an ingredient with whose properties everyone is familiar. Olive oil. The one undergoing fermentation contains 50 times more omega-6 and omega-9 than its unfermented counterpart.

Fermentation of ingredients is a completely natural and non-invasive process.

Fermentation is a natural process that enriches plant extracts without altering their beneficial properties, producing substances that cannot be reproduced artificially.

  • Fermentation of Korean cosmetic ingredients keeps intact and preserves the natural properties of the active ingredients.
    Fermentation reduces the use of preservatives by preventing the loss of active ingredients due to heating of the ingredients during the cosmetics manufacturing process, thereby extending the shelf life of the products.
  • Fermentation of ingredients in Korean cosmetics results in formulations suitable for all skin types.
    The transforming action of cosmetic ingredients by microorganisms produces a simplification at the organic level of the cosmetics. This makes the formulations generally well tolerated by all skin types, especially sensitive skin.
