​How to get glowing skin with fermented ingredients!

Louis Pasteur’s discovery of fermentation allowed us to understand the process of yeast converting sugar (glucose) into ethanol. Microbial action during years of captivity, darkness and isolation converted the young, sugary fruit juice into old, deep and intoxicating wine, one with higher antioxidant properties than fruit juice. And with wine, they say, the older the better, right? What if we told you that the same fermentation principle works to turn back time for your skin as well?

Although housing a secret known for ages, it is only now that Korean skincare has seen a boom in the Western world. But thanks to it, fermentation is now being viewed as more than just a way to preserve pickles. There are, in fact, entire k-beauty lines dedicated to fermented and ‘probiotics’ ingredients.

What is fermentation?

Fermentation is the time-specific chemical action of microorganisms on a substance. The word is specifically used when referring to microbial actions that convert sugars into other substances. These microorganisms (different kinds) release enzymes to break them down.

Grape juice is fermented into wine when yeast (a microorganism) consumes the sugar in the grapes. Kombucha, another drink trending in all the modern cafes these days, is also a product of fermentation.

Fermentation preserves edibles as microorganisms act on them. Bacteria are generated as a result of soaking edibles in their own water or external salt water that then feed on the natural sugar in the substance, producing lactic acid. In turn, this makes it difficult for prying microorganisms to feed off of them, preserving the food item. Yes, the lactic acid is exactly what gives the edible it tardy taste if that’s what you’re wondering.

Here’s another thing you must be wondering: sure that’s great for making achaar, but what does any of it have to do with our skin? Well, you are just about to find out!

What can fermented ingredients do for your skin?

Incorporating fermented ingredients into skincare is yet again a k-beauty secret making headlines in this part of the world. Its time-proven success has convinced researchers and beauty product manufacturers of its efficiency and effectiveness. Below we listing all the known benefits of fermented ingredients for skin.

1. The nutrients are easily absorbed by the skin

Natural remedies like rubbing an edible on your skin (bananas, citrus fruits, etc.) do not work for the majority of people simply because the molecule size of their nutrients is too large to be effectively absorbed and broken down by the skin. Fermented ingredients, however, have a much smaller molecule size and are easily absorbed by skin because the microbial activity has already broken them down. This means they can be easily utilised to nourish the skin and won’t remain at the surface.

2. You don’t have to worry about rashes or unwanted reactions

Again, even though the benefits a DIY tomato mask or a banana and honey mask are sworn effective by many DIY enthusiasts, they certainly can irritate skin, especially people with sensitive skin. Similarly, using other raw natural ingredients on your face may cause burns or a breakout due to the additives and toxins contained in them. Fermented ingredients are free from nasty metallic traces, pesticides and other irritants that can cause unwanted reactions. The interaction and effects of fermented ingredients very much mimic our natural skin cell functions, making them safer and suitable to use for all skin types!

3. Fermentation produces by-products that are beneficial to the skin

As mentioned above, the action of microorganisms produce lactic acid and other by-products. But what exactly are these by-products? Fermentation releases Alpha Hydroxy Acids (AHAs), amino acids, vitamins and beneficial natural skin sugars that do wonders for the skin. They slow down the aging process by increasing the natural turnover of skin cells, keeping your skin younger for longer. 

4. Anti-inflammatory properties make it suitable for treating acne

5. Fermenting can increase the amount of active ingredients and nutrient density

In many cases, fermenting can increase the amount of active ingredients present in the substance in question. This is why fermented foods are so praised and sought after. They contain live probiotics and cell walls of dead probiotics that interact with the immune system to enhance its function. They also increase vitamin content, zinc and folate quantities. Looking at skincare, consider soy which is more effective in fermented form than the unfermented version. Soy contains two forms of isoflavones, namely daidzein and genistein. According to studies, daidzein and genistein are responsible for increasing hyaluronic acid production in the skin, which helps greatly with skin dehydration problems and also with signs of aging such as fine lines and wrinkles.

6. Fermentation increases a product’s shelf life

Enough microbial activity has been achieved in fermented products to reduce the need for adding any preservatives to a product to increase its shelf-life. This makes such beauty products relatively safe and healthy to use.

Which fermented ingredients should you look out for?

K-beauty skincare products use fermented fruits, tea (kombucha), yeast, herbs, rice, seaweed and roses, all of which have proven skin benefits. Consider:

• Fermented yeast: The action of fermented yeast stimulates healthy collagen production. Collagen is a protein that ensures the integrity and structure of your skin, bones, tendons and ligaments. Stimulating its production means firmer, plumper and more elastic skin, giving a more youthful look.
• Fermented black rice: Fermented black rice is packed with antioxidants that combat the effects of environmental aggressors like pollution, UV rays, dirt and debris, etc. and also work to brighten the complexion.
• Fermented soy: Fermented soy deeply hydrates, nourishes and moisturises your skin and helps delay the signs of aging.
• Fermented maqui berry: Native to Chile, the maqui berry, also known as the Chilean berry, offers a range of benefits for the skin. Packed with antioxidants like flavonoids, anthocyanins, and polyphenols, this little fruit is an all-rounder when fermented, preventing environmental damage, regenerating healthy skin cells and balancing uneven skin tone.
• Fermented red ginseng: Fermented red ginsengbrightens skin and fights wrinkles and fine lines, giving your skin a healthy glow and radiant finish.

Are fermented ingredients suitable for my skin?

As with all skincare tips and remedies, fermented ingredients may not be suitable for everyone. But before jumping to any conclusions, do some thorough research:

• Ensure the skincare product you are choosing has ingredients fermented with natural processes so it is free of harmful chemicals and additives.
• Find the right type of product for your skin type. For example, if you suffer from discolouration or an uneven skin tone, find a product containing active ingredients that fade pigmentation.
• Opt for products such as essences that are water-based and have a runny consistency. They are versatile, the most easily absorbed into skin, and can be used regardless of the season.

Should you consume fermented edibles for healthy skin?

Now you’ve learned the benefits of applying fermented ingredients, the only question remains, will consuming them have the same effect? Here’s a little insight if you’re not already familiar with this concept. Your digestive system plays a significant role in determining the appearance of your skin. A healthy tummy is a healthy face, believe it or not! It isn’t uncommon for people with digestive system problems to suffer from acne or related skin disorders. Fermented edibles are easily digestible and easily absorbed, so yes, they do play a role in increasing skin health.

But consume too much and their acids will cause ulcers and increase the risk of gut cancer. Balance is key, but it is not easily realised by many. Also, because of our unique bodily types and metabolisms, it is hard to say how much is “too much” for someone. It is better to stick to applying fermented ingredients to your skin and not consume them in excessive amounts in hopes of better skin.

Conclusion:

Just like many other Korean skincare secrets we’ve uncovered over the last few years, fermented ingredients, too, have been in use in k-beauty for hundreds of years. These pre-digested food substances are easily absorbed by the skin and are rich in nutrients that help your skin’s cellular renewal, giving you smooth, even toned, and energised skin. Look out for products containing Bifida ferment lysate, Galactomyces ferment lysate or Saccharomyces ferment lysate (lysate or filtrate). Make sure to conduct a patch test to ensure the product is right for you. You will be flaunting your healthy, glowing skin in no time!
