“Fermentation” is Gaining Attention in The Beauty Industry!
Did you know that fermentation, which has been beloved in Japan for centuries, is now gaining attention in the beauty industry? When you see the word “fermentation,” you might associate it with health foods that have long been loved in Japan, such as natto, miso, and soy sauce. Just as fermented foods support health by improving gut health, it has been found that fermented ingredients also have various positive effects on the skin. So, what is the relationship between fermentation and skincare?
What is Fermentation?
So, what exactly is fermentation?
“Fermentation” is the process in which food is broken down and substances are transformed through the action of microorganisms, making the food tastier or creating beneficial components for humans. On the other hand, when harmful substances are produced that can make food unpleasant or cause stomach issues, it is called “rotting.”
Skincare Benefits of Fermented Ingredients
The components produced during the fermentation process are said to have a positive effect on the skin.
- Moisturizing Effect
Amino acids, lactic acid bacteria, and hyaluronic acid produced through fermentation enhance the skin's ability to retain moisture, keeping it hydrated for a long time. They help maintain soft, supple skin and improve skin texture.
- Whitening Effect
Enzymes and organic acids (such as kojic acid) produced through fermentation help inhibit melanin production, preventing dullness and dark spots. They enhance the skin's transparency and support a brighter complexion.
- Strengthening the Skin’s Barrier Function
Fermented ingredients help balance the skin's natural microbiome and strengthen the barrier function that protects the skin from external irritants. In particular, ingredients derived from lactic acid bacteria are suitable for sensitive or dry skin.
- Anti-aging Care
Polyphenols, peptides, and vitamins produced through the fermentation process have powerful antioxidant properties that prevent skin oxidation. This helps prevent wrinkles and sagging, maintaining the skin's firmness and elasticity.
Fermented Ingredients Used in KURAMOTO-NO-SHIZUKU
The Kuramoto no Shizuku series also uses a lot of fermented extracts!
- Rice Fermentation Liquid
The rice fermentation liquid included in the medicated whitening and wrinkle improvement cream is made by fermenting rice with the help of microorganisms to extract beneficial components for the skin. This unique ingredient is primarily expected to provide moisturizing effects through various amino acids and vitamins. It is easily absorbed by the skin and can be comfortably used in any season. Additionally, it is safe for various skin types, helping to improve skin while also enhancing transparency, leading to beautiful skin.
- Sake Lees Extract
An essential component of the Kuramoto no Shizuku series is sake lees extract. Sake lees, known as a fermented food, is used in the production of this extract. Sake lees extract, derived from the lees of sake during its production process, has been recognized for its skin-beautifying effects for a long time. It contains abundant nutrients from fermentation, offering various skincare benefits. Specifically, the kojic acid and ferulic acid found in sake lees help inhibit melanin production, preventing dark spots and dullness, and promoting transparent, beautiful skin. This is one of the reasons why the hands of sake brewers are said to be white and beautiful.
- Yogurt
Yogurt, a representative fermented food, is also included in Kuramoto no Shizuku. The lactic acid and whey in yogurt have properties that attract moisture, helping to maintain the skin's hydration. Additionally, it gently exfoliates the skin, promoting skin turnover, and helps balance the skin's natural microbiome, protecting it from external irritants. This makes it a beneficial ingredient for those with dry or sensitive skin.
- Coix Seed Fermentation Extract
The White Pearl Esthe, a泡 (foam) cleanser, contains Job's Tears Fermentation Extract. This extract is a skincare ingredient that enhances the absorption of effective components by fermenting Job's Tears. Rich in amino acids and minerals produced through fermentation, it is expected to provide moisturizing effects, leading to soft and hydrated skin. Additionally, the coixolignans found in Job's Tears help inhibit melanin production, preventing dark spots and dullness.
- Yaezakura Yeast Extract
The Kuramoto no Shizuku Sakura Yeast Serum uses natural yeast derived from Yaezakura cherry blossoms in Kenrokuen. Yeast extract is obtained by extracting the beneficial components from yeast, and it has been found that the vitamins, minerals, and other components contained in yeast extract not only benefit the body when consumed but also have positive effects on the skin. Mainly, it helps repair damaged cells, guiding the skin’s turnover to a normal state, protecting the skin from external irritants, and inhibiting the production of melanin, leading to beautiful, radiant skin without dullness.
- Honey Fermentation Extract
The concentrated night pack that targets skin dullness contains honey fermentation extract. This extract is produced by fermenting honey, which increases the concentration of active ingredients, enhancing its absorption and effectiveness on the skin. It provides moisturizing and barrier functions, and the anti-inflammatory properties derived from honey help reduce redness and acne inflammation, preventing skin troubles.
Summary
Fermentation increases the nutrients necessary for the skin and transforms them into a more absorbable form, enhancing skincare effects. By incorporating fermentation-based skincare, which harnesses the power of nature, we can aim for healthy and beautiful skin.
