The so-called "toxic contact eczema“Is based on direct contact of the hands with irritating substances. Our hands often come into contact with harmful substances in everyday activities or at work.

Hand, foot and mouth disease
Typically, children get the virus-borne rash. Occasionally, however, adults also suffer from the condition.
The highly contagious pathogens spread via droplets and cause skin rashes in the hands, feet and mouth. Hand, foot and mouth disease is usually associated with painful inflammation of the oral mucosa.

Various factors also promote the development of dry skin. In particular too frequent hand washing using soap can permanently damage the barrier.
