Features Our hot springs are rich in metasilicic acid, which is a natural moisturizing ingredient, and are also known as "hot springs of beauty." Normally, when it exceeds 100mg, it is said to be "beauty hot water", but the hot spring at our hotel has more than twice that amount, 212mg, and we have received many compliments from our guests.
What is metasilicic acid Metasilicic acid is also called a “natural moisturizing ingredient” and is said to be highly effective for beautiful skin. Metasilicic acid is called a natural moisturizing ingredient because it has the following three actions.

Promote skin turnover
Metasilicic acid has the function of increasing metabolism. As the metabolism increases, the old keratin falls off and is replaced with new cells. By repeating the normal turnover, you can maintain healthy and firm skin.

Protect skin from dryness
Metasilicic acid helps the production of ceramides that keep the skin's keratinization in balance. Ceramide is a component that binds skin cells together to prevent evaporation of moisture and oil inside the skin. By soaking in hot water containing metasilicic acid, you can activate the action of ceramide and keep the moisture and oil content of your skin moderate. Therefore, you can expect the effect of protecting your skin from dryness.

Create beautiful skin and hair
Metasilicic acid contains about 35.9% "silicon". "Silicon" is a mineral necessary to generate skin and hair. Therefore, by ingesting metasilicic acid, you can get beautiful skin and hair.
