What is the "hot water for beautiful skin"?



There are several kinds of spring that are cold "hot water for beautiful skin", and this time we focus on one of those, which is "Sodium-hydrogen carbonate spring".

"Sodium-hydrogen carbonate spring"

The name sounds difficult to understand, but it used to be called "bicarbonate" spring.

Many of you may have heard of baking soda, and it is also called Sodium-hydrogen carbonate, which is used for cake baking or cleaning.

It has various effects such as polishing effect, neutralizing effect, changing "hard water (with more minerals such as calcium and magnesium)" to "soft water (less minerals)", and baking soda is functioning inside of our bodies.

Recently baking soda has become popular and you can buy it in supermarket, home center or drugstore.

Baking soda spring cleans off dirt or dead skin from your skin thanks to the function of baking soda. This is called emulsification. If you soak in bicarbonate spring, you can expect smooth and white skin. It's possible to make hot water for beautiful skin at home, which contains the same components with the spring, and you may feel clear skin after the bath.

But please bear in mind that after cleaning off the dead skin, your skin becomes more weak to dryness. So keep moisturizing care to your skin after bath!
