What is Sulfide ion?

Sulfide ions (S²⁻, HS⁻) are the key components of sulfur springs. They are said to have strong antibacterial action on the skin surface.

Main Effects

  • Antibacterial actionHydrogen sulfide, a key component, is said to have a strong sterilizing effect, inhibiting the growth of bacteria such as Staphylococcus aureus on the surface of the skin. This action is said to help keep the skin clean.
  • Indicated for atopic dermatitis and psoriasisChronic inflammatory skin conditions are listed among the indications for these springs, which are said to have antibacterial and keratinolytic (skin-softening) effects.
  • Characteristic rotten-egg aromaThis distinct scent is characteristic of hydrogen sulfide (H₂S), a primary component of the spring. The aroma is often compared to boiled eggs because it originates from the same type of sulfide compounds that are also found in egg yolks.
