Popular skin care products like Sulwhasoo are known for their effective formulas and skin care benefits, but there are also fermented products that offer similar solutions. Fermented products have been praised throughout history for its health benefits, but it is also becoming a trend in the skin care industry. Research has been showing the benefits of fermented skin care products and fermented gels, creams, moisturizers, serums, and toners are available in the market today.

The Science of Fermentation

According to a 2002 study in the Journal of Agricultural and Food Chemistry, the wine had a greater overall antioxidant capacity (AOX) than grape juice. Also, a  study conducted by the Journal of Medicinal Food found that fermented red ginseng had increased whitening and wrinkle eliminating properties compared to traditional red ginseng.

Lastly, a study in Dermatologic Therapy in 2007 also reported that fermented yeast extract helped diminish the signs of skin aging by improving collagen synthesis. Collagen is a fibrous protein that is the main component of skin and connective tissues. Thus, promoting the creation of collagen is crucial in keeping your skin firm, which fermented skin care products facilitate.

Here are the benefits of using fermented skin care products:

Fermented products are better absorbed into the skin

Fermented skin care products have been a rage after organic skin care products. Plant actives normally aren’t effectively absorbed into the skin because the molecular size of the actives is too large. By going through the fermentation process, these plant actives are broken down into smaller sized molecules, making them more readily absorbable into the skin. Also, as the fermentation process breaks down these actives, minerals and nutrients are released from the plant microfibers that are effectively absorbed into your skin.

Fermentation lessens skin irritation

Some raw materials may still contain toxins like pesticides and heavy metals that irritate the skin. The fermentation process neutralizes these toxins, making the product safer for your skin, especially for those with sensitive skin. Fermenting yeasts also create their own antimicrobial properties, thus eliminating the need for preservatives and extending product shelf life.

Fermentation creates new beneficial byproducts.

The fermentation process produces new amino acids and peptides that aid skin cell renewal. These new substances work synergistically that speed up your skin’s rejuvenation process, thus leading to a brighter and glowing complexion since old skin cells are turned-over with new ones.

Enhance blood circulation.

Because it is readily absorbed into the body, your skin signals your blood to pick up nutrients from the area, just as eating kimchi (fermented cabbage) aids digestion. it also promote blood circulation, thus enhancing your skin’s radiance.

Suitable for sensitive skin.

Fermented skin care products are non-drying and less harsh compared to non-fermented skin care products, making them ideal for sensitive skin types and effectively deal with redness and irritation. They also have nourishing and hydrating properties and strengthen the skin’s barrier, which are all critical issues when you have sensitive skin.

Work naturally with your skin.

Fermented skin care products mimic natural skin cell functions and do not cause adverse reactions when applied on skin, making it ideal for sensitive skin types who often adversely react to conventional skin care products. They also have a longer shelf life compared to conventional To this product and don’t need any preservatives because they’ve gone through the fermentation process and already have natural antimicrobial properties.

Fermented Skin Care Ingredients

Some fermented skincare lines use traditional ingredients like black soy, sea kelp, fermented ginseng, and fermented olive leaf extract into their products. A popular fermented product called kojic acid is created from fermented rice wine (sake) and is used in many whitening soaps, lotions, and skin care products.

However, are mineral-based and use a yeast like Saccharomyces and galactomyces for the fermentation process. These yeast strains are mixed with minerals such as zinc, copper, and magnesium so that they can be converted into mineral peptides that are more readily absorbable into the skin. The yeast is then removed after the fermentation process, leaving only the mineral peptides in the product, although some products keep a small number of probiotic bacteria for added benefits and shelf life.


Research has shown that fermented products are not only good for your digestive health but also works wonders for your skin. However, it may not be suitable for everyone and some people might be allergic to the yeast and microorganisms in it . Do a skin test first before buying the entire product and check with your dermatologist to see if fermented skin care products are ideal for you.
