What is Bicarbonate ion?

Bicarbonate ion (HCO₃⁻) — the same ingredient as baking soda — gently removes old skin cells and sebum for silky-smooth skin. Known as the "beauty spring" (美人の湯).

Main Effects

  • Removes dead skin cells and sebumThe weak alkalinity of bicarbonate ions, the same component as baking soda, helps soften keratin in the skin's outer layer. This process also emulsifies oils and sebum, washing them away much like soap does.
  • Skin beauty effect (美人の湯)This type of spring water is said to soften old skin cells on the surface. This is why these springs are often called "Bijin-no-Yu" or "Baths of Beauty," leaving your skin feeling exceptionally smooth.
  • Indicated for digestive conditions when drinkingWhen consumed, the bicarbonate ions can help neutralize excess stomach acid. This action may help alleviate the symptoms associated with conditions like gastroduodenal ulcers and reflux esophagitis.
