1-30. Aim for tough skin(日本語


Skin problems are increasing every year.

Rough skin, acne, pimples, etc.
Most of this is the normalization of the problem due to the decrease and imbalance of the skin’s residental bacteria.

It is aggravated by wrong skin care on a daily basis and solved by medication, which causes further loss of bacteria and disruption of the balance.

Even if you try desperately to get cleaned up quickly, the wrong way will not solve the problem at all.
To begin with, unnecessarily nourishing weak skin is counterproductive.


So, this is the savior of such skin troubles.


They are the “main player” that protect our skin.


Propionibacteria break down the sebum on our skin and produce the propionic acid and glycerin
It produces a “moisturizer”.


The skin does not become fresh by only using sebum, which is oil.


The propionic acid and glycerin produced by the propionibacteria are special ingredients that can blend in with both oil and water.

They spread thinly on the skin along with the sebum, and at the same time, they have a water-retaining effect, absorbing water and keeping the skin fresh.


In fact, this is a little-known function of skin moisture retention!


In other words, sebum must be broken down by propionibacteria to maintain fresh skin.

Furthermore, propionic acid makes the skin moderately weakly acidic, preventing the growth of other inconvenient bacteria and viruses.


If our skin isn’t moisturized enough or has ended up in pharmaceuticals due to improper care, increasing propionic acid bacteria is the way to go!


So how can propionibacteria increase?

We seriously considered the cultivation of the skin indigenous bacteria.
And the one that was born through trial and error is

Microbial culture cream!

This cream contains nutrients that allow propionibacteria to grow predominantly.

<It’s great because it really does increase the amount of residental bacteria! >


We grow and cultivate the propionibacteria, and make the skin that is not defeated by the external environment.

The skin where the propionibacteria are healthy is exactly the “Tough skin” as our ideal.
