How Fermented Cosmetic Will Change Your Life – and What K-Beauty Bloggers Think About It


I swear you’re not gonna flee from this other ‘weird beauty trend’. Fermented cosmetic is probably one of the best ways to go for a clean, purified and reinforced skin. I’ve been away for a while now, I moved in a new city (Saint-Etienne) and I didn’t really have time for blogging but what I had time for is trying and interviewing bloggers about the so-new-to-the-West fermented cosmetic trend. On one hand, I’d like to apologize for not updating the blog so often. On the other hand, however, I know you’ll forgive me when you’re done with this post – which presents a little introduction, interview of two bloggers who LOVE fermented cosmetics and my personal tips for DIY masks!



Fermentation is a technique that has been trusted by Asia for dozens of centuries now, in food, in drinking and in beauty. In the West, we’re less fond of fermented items for the sake of a presumed sanitary aspect – bacteria and friends.  Even if we French or Italians swear by cheese (and especially when it has little blue stains all over it) the Occidental world doesn’t seem really familiar with other fermented products than Greek yogurt. And that’s nothing to blame it for. Culture, history, y’know.


The point is, even if some brands like Estée Lauder have been resorting to the fermentation process for its cosmetics, the idea is mostly Asian. Most famous brands are SK-II (Japan) with its Pitera extract that changes skin (and life, apparently) and SU:M37 (Korea) which proposes fermented ingredients only. I’ve never – not once, and I worked in the industry on spot – heard anything bad or any disappointment regarding these two (unless unexpected allergies and reactions that arise not from the fermenting but from the core ingredient itself) and when you think about it, Japan’s new craze Yokuinin (click for more info) also results from fermentation.


So you might be wondering: why is fermentation so good to the skin? Well, let me explain, it’s rather simple. There is, on Earth and against most beliefs, bacteria that aren’t harmful to the human body. More than that, we need them. When most people here hear about bacteria, they freak and forget we’re made of it, too. And they’re in many things we ingest everyday (yogurt, cheese, some soups). Fermented cosmetic consists in focusing on these human-friendly bacteria and grow them into super-skin-doctors who work from within the dermis and body. They activate (or reactivate) blood circulation and help reinforcing barriers, they complement cell regeneration and also help purifying body from toxins. What a life-saver.


Mary, from The Point of Vu, and Laven, from Berries In The Snow, are two beauty bloggers of wide activity range who share a little passion for K-beauty. I got to work with these amazing and professional girls back then when I was working in cosmetic promoting in Seoul and I gotta say their blogs are source of knowledge and beauty wisdom. They were nice enough to answers a few questions and share with us what they know, think, and like about fermented cosmetics.

I actually found out about fermented cosmetics when I was randomly browsing the Sephora website about a year or two ago! I remember hearing so much hype about SK-II, that was the first brand I found out about that used a fermented process, and it really intrigued me. However, the price point for SK-II was way too high for my college student budget, so the first fermented product I tried was the Missha Time Revolution First Treatment Essence. The first time I heard about fermented cosmetics was when I stumbled over the Japanese luxury brand SKII and their Facial Treatment Essence containing fermented yeast filtrate. Their essence was discussed like it could bring up wonders! Since it is and was too expansive for me to ever try anything from this brand my second encounter with fermented cosmetics was when the first dupes for the SKII essence entered the market, like from Secret Key and from Missha. Finally products were available which were affordable and had almost the same ingredients like the famous SKII essence.




A major quality I love about the fermentation process is that the ingredients in the products are broken down into small, but more concentrated molecules making the ingredients more easily and quickly absorbed — this quality is a huge plus because it penetrates my dry skin almost instantly while hydrating and repairing it! Another major quality of this process is that it really helps my skin look and feel more youthful! My skin always feels a lot more plump and supple to the touch whenever I use fermented cosmetics. All the reviews about these so-called first essences had one thing in common: they stated that the essences were making the skin feel very smooth and soft! This is probably not only the effect of the fermented ingredients, but also of other ingredients which are part of the essences. Many of the first essences use sugars and niacinamide or lactide acid for additional moisturizing and brightening effects. Nevertheless, yeast ferment filtrate, also known as “Pitera”, is nutrients-rich. It contains many vitamins, amino acids and proteins and helps to improve the moisture level of the skin.




Anything from SU:M37! SU:M37 is one of my top favorite brands and it’s a whole brand dedicated to fermented ingredients! I also really enjoy using the Missha Time Revolution The First Treatment Essence and BRTC’s The First Ampoule Essence. It is hard to decide for only one product, because there are so many different types of products by now which contain fermented ingredients. We have products with yeast ferment filtrate, but also a numerous amounts of products with plant derived fermentation filtrates. My favorite product I’ve tried so far would be the Missha Time Revolution First Treatment Essence. If I could choose a second and third product it would be the Tosowoong Syn-Ake Natural Pure Essence and the From Nature eChoice Fermented Tea Sleeping Pack, which are both very affordable and nice products, too.




I only used fermented cosmetics in my skincare routines and mostly at night. About 98% of the time, I’m using essences with fermented ingredients which I apply after cleansing my face and before my moisturizer. I use almost daily a first essence, like the Missha Time Revolution First Treatment Essence. I don’t use it like toner, but after toner and actives, like for example vitamin C. other products, like sleeping masks or ampoules I use if I have a lot of time for pampering. But even when only using the essence I feel my skin being smoother and happier.




I LOVE eating greek yogurt in the mornings for breakfast. I also really enjoy kimchi, and a lot of other fermented Korean side dishes — I can’t live without them! I love Greek Yoghurt and all those yoghurt related products! Also Ayran (a yoghurt/salt drink) is part of my diet since my childhood because of my ethnic background. Another fermented food which you will find often in Germany is bread made of sourdough. Sauerkraut is also quite common in Germany, but I only ate it once or twice in my life. I bought some miso paste recently for cooking more Asian food in future, but so far I didn’t use is as often as I do use soy sauce.

Now that you have a better understanding of what fermentation means in beauty, that you added some products on this month’s shopping list, it’s MASK TIME – yay! Who doesn’t love mask time?

What’s the most basic fermenting product that you know? Yep, yogurt. And today you’ll find out how great of a purifying and soothing beauty balm Greek yogurt can be! All you need is Greek yogurt, honey and cinnamon as a little extract if you want to exfoliate!

  • Mix half a Greek Yogurt with two tea spoon of honey – but be careful not to obtain a liquid texture.
  • For exfoliating properties, add a tea spoon of cinnamon powder to the mixture.
  • Store in the fridge for a couple hours at minimum.
  • Apply a rather thick layer on a clean and dry face and leave it for 10 to 15 minutes.
  • Rinse with warm water and finish up with a cold water.
  • If you added cinnamon powder, rinse in circular motions to extract all dead skins.

The skin is brighter, more supple and smoother!

    1. Thank you Laven, it was really nice having you, I hope we can do it again in the future! 🙂
      You can make the same mixture with the other half of the yogurt and eat it – it’s not bad at all! :p

  2. Obviously I’ve heard of SK-II and SU:M37, but I’ve never put much thought into their ingredients. I guess I need to have a look if I own anything fermented!

    I used to do this greek yoghurt mask a lot when I was younger, because I read about it from gyaru blogs. 🙂 I never added cinnamon, though, so that’s new!


    1. So this is where your flawless complexion is coming from! Cinnamon is efficient for exfoliation and brightening in this recipe 🙂
      Thanks for stopping by, Lona!


  3. I love it! Thank you so much again for featuring me on your blog — It was so much fun! 😀 I love how Laven and I have some really similar answers especially how we both found out about fermented products because of SK-II haha. This is such a great blog post! ^^


    1. I’m so glad you like it, I was really happy to have you here too! I guess we all start with SK-II, it’s a real beauty institution, isnt it? Thank you for your kind words , Mary:)
