Characteristics Our hot spring is known as the 'Beauty Bath,' as it is exceptionally rich in natural moisturizing components, specifically metasilicic acid. Typically, when the content exceeds 100mg, it is referred to as the 'Beauty Bath.' However, our hot spring boasts a remarkable value of over 212mg, eliciting much praise and delight from our bathers.
What is "Metasilicic acid" Metasilicic acid, also known as a 'natural moisturizing component,' is believed to have a high skincare effect. The reason metasilicic acid is referred to as a natural moisturizing component lies in its three main actions:

Promotes skin turnover
Metasilicic acid has the ability to boost metabolism, facilitating the turnover of skin cells. By enhancing this process, old keratin is shed, making way for the replacement with new cells. Regular turnover supports the maintenance of healthy, resilient skin.

Protects the skin from dryness
Metasilicic acid aids in the production of ceramides, which help maintain the balance of skin keratinization. Ceramides are components that bind skin cells together to prevent the evaporation of moisture and oil within the skin. Immersing in water containing metasilicic acid activates the function of ceramides, ensuring a moderate retention of skin moisture and oil. Therefore, it is expected to have a protective effect against skin dryness.

Creates beautiful skin and hair
Metasilicic acid contains approximately 35.9% of 'silicon.' 'Silicon' is a mineral essential for generating skin and hair. Therefore, by incorporating metasilicic acid, one can attain beautiful skin and hair.
