The K-Beauty Secret to Fermented Ingredients

by Michelle Li

Kimchi is just one food that you’ll find stocked up in all Korean families’ fridges. Most commonly made out of cabbage, it’s spicy but most importantly fermented making it amazing for your body. The fermentation process of it all releases natural probiotic bacteria and just one of the benefits is it’s able to strengthen your gut microbiome to improve digestion. Which is why you’ll even find fermentated prebiotics and probiotics in inner beauty care drinks like Teazen’s Kombucha. But why should we stop fermentation at food?


Well in K-beauty, there are many fermented skincare products because it simply offers plenty of benefits. The fermentation process of skincare comes from the use of microorganisms like yeast or bacteria to break down certain skincare ingredients. This process creates a number of benefits!

Firstly, the ingredients’ molecular structure becomes a lot smaller. This allows the skincare ingredient to penetrate deeper into the skin for effective results. The fermentation process also produces more amino acids, vitamins and minerals which are all vital to maintain healthy skin. That’s not all though! Fermented skincare also initiates our skin cells to turnover faster. This naturally speeds up our skin cell renewal to reveal soft smooth skin all in a glowy, glass-skin complexion ✨

But one of the most important benefits of fermented ingredients is that it protects our skin from environmental stressors like pollution, UV rays, and radiation by balancing our skin’s microbiome. A healthy microbiome keeps the ‘bad’ bacteria out to maintain a strong skin barrier. It’s just like how fermented food keeps our gut health strong! So by building a strong skin barrier, it prevents skin concerns like acne, hyperpigmentation and can even slow down down aging.

And lastly, this isn’t necessarily correlated with our skin but I’m sure this is something we all would love! Fermented ingredients have a longer shelf-life. If we think about how much longer yoghurt and kimchi lasts, skincare too can have a longer shelf life from fermented ingredients. With so many benefits, there’s no reason to not include it in your skincare routine. So let’s take a look at some skincare products, fermented edition:

Numbuzin No. 3 Super Glowing Essence Toner


This Numbuzin Essence Toner from their No. 3 line actually has 50+ fermented ingredients so you can really reap in the benefits that fermentation offers. It smooths skin texture and evens out your skin tone while elevating hyperpigmentation, that’s age spots, acne scars, freckles etc. This toner is very hydrating too! This helps to plump up your skin, lifting fine lines while giving you glassy skin. If you want to see all the skin benefits fermentation has to offer, definitely look into this Numbuzin toner.

Heimish Matcha Biome Amino Acne Cleansing Foam


For those with acne-prone skin types, it can be a struggle to keep the breakouts under control. But fermented ingredients are a great way to heal the skin. It is likely that if you are constantly getting breakouts, your skin barrier, or the microbiome is quite weak. So get it back to health with this Heimish Cleansing Foam. It uses fermented matcha extract combined with probiotics and enzymes so not only are you strengthening your skin barrier, but the matcha extract can control excess sebum too. This cleanser also contains 0.5% salicylic acid, a small amount that won’t irritate the skin further but enough to unclog pores and prevent pimples 🌚

Rovectin Clean Forever Young Biome Ampoule 


I personally opt for clean beauty brands as I find it works best for my sensitive skin. Rovectin actually started after first developing skincare for post-cancer treatments. This means their products have to be super gentle on the skin. This Biome Ampoule from Rovectin’s Clean line relies on fermented prebiotics AND probiotics to do the work. It’s an oil-free formula that helps to reduce signs of aging while truly hydrating the skin from inside-out, one of the best ways you can strengthen sensitive's skin weak barrier.

Pyunkang Yul Black Tea Enriched Cream


Black tea contains a LOT of antioxidants to help protect your skin from environmental stressors. It’s super important, as without this protection, it’s one of the fastest ways to speed up ageing. But what’s even better than just black tea on its own? Of course, if it’s been fermented! This Pyunkang Yul Black Tea Cream contains many polyphenols and catechins of black tea that are only developed during the fermentation process. It's exactly what you need to plump fine lines and wrinkles!
