Recommended not only for skin beautification but also for gynecological diseases. It is a hot spring for women.


Bentenkaku's hot springs are said to have cleansing and moisturizing effects, so I think it would be a great pleasure to get a smooth, smooth, plump and moisturized skin.


Spring quality


Bentenkaku's hot springs are of the "sodium-bicarbonate / chloride / sulfate spring" quality.


carbonate spring Smooth skin with hydrogen carbonate spring


A "bicarbonate spring" is when the total amount of dissolved substances in 1 kg of hot spring is 1000 mg or more and the main component of anions is hydrogen carbonate ions.


"Hydrogen carbonate spring" was divided into bicarbonate earth spring (calcium hydrogen carbonate spring and magnesium hydrogen carbonate spring) and baking soda spring (sodium hydrogen carbonate spring) in the old spring quality name.


In particular, this baking soda spring (sodium-hydrogen carbonate spring) is a hot spring that can be expected to have a cleansing effect that cleans the skin, and acts like a soap that softens the surface of the skin, emulsifies sebum, and removes dirt. increase.


It is a hot spring quality that is often found in hot springs called "Beautiful skin hot springs" that make the surface of the skin smooth. The first thing that comes to mind as an image of beautiful skin is and texture, and this hot spring has the quality of a spring that makes such smooth skin.

Chloride spring Chloride spring
that wraps the skin with a thin veil


A "chloride spring" is when the total amount of dissolved substances in 1 kg of hot spring is 1000 mg or more and the main component of anions is chlorine ions. The main ingredient is salt, so it tastes salty when you lick it.


Characteristically, the salt component adheres to the skin and wraps the skin like a thin veil. Even after the bath is finished, it acts as a protective film to prevent the skin from drying out and prevent moisture and heat from escaping, so you can expect a warming and moisturizing effect that will keep your skin <moist> and <other> beautiful.


If you go to the beach, swim in the sea, and then expose yourself to the sun, a slight white salt may remain on your skin. Similarly, the salt component in the hot spring remains on the skin.


Chloride springs have a moisturizing effect that keeps the salt covered and keeps warmth even after the hot springs are warmed up. It is also a hot spring that I would like to recommend.

Sulfate spring A hot spring with
plenty of beauty and anti-aging skin


A "sulfate spring" is when the total amount of dissolved substances in 1 kg of hot spring is 1000 mg or more and the main component of anions is sulfate ions.


Depending on the main components of the cations, they are classified into "sodium-sulfate springs (sulfate springs)", "calcium-sulfate springs (gypsum springs)" and "magnesium-sulfate springs (massive springs)". There is a lot of yellowish and slightly cloudy hot water, and it is characterized by a slight bitter taste when licked.


There are many hot springs with legends such as healing the wounds of various military commanders from ancient times, and it is said to be suitable for trauma and arteriosclerosis. It is a nice spring quality that can be expected to restore the skin-beautifying power because it restores the elasticity of wounds and blood vessels.


In particular, "sodium-sulfate spring (sulfate spring)" is expected to promote collagen production and activate antioxidant defense mechanism, so it is also incorporated into commercially available bath salts <moisturizing ingredient>. is. It is an "anti-aging hot water" that activates the skin-beautifying power that tends to decline.
