What is Sulfide ion?

Sulfide ions (S²⁻, HS⁻) are the key components of sulfur springs. Their strong antibacterial action removes bacteria and irritants from the skin surface.

Main Effects

Antibacterial actionHydrogen sulfide, a key component, possesses a strong sterilizing effect. It works by powerfully inhibiting the growth of bacteria, such as Staphylococcus aureus, on the surface of the skin. This action helps to cleanse the skin and remove potential irritants.
Indicated for atopic dermatitis and psoriasisThe spring's properties may help manage chronic inflammatory skin conditions. Its combined antibacterial and keratinolytic (skin-softening) effects can help control the symptoms associated with these ailments by cleansing the skin and removing substances that cause atopy.
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.
