- Eczema is a pruritic dermatosis that manifests itself by a non-contagious inflammation of the skin which is accompanied by redness, fine vesicles, dander and itching. People who have it experience periods when the disease manifests as flares during which symptoms worsen and then subside. These episodes of relapse and lull or remission spread over a more or less long period, especially in adolescents, which can be very disturbing in adolescents.
- the aesthetics of eczema can range from bright red patches spread over a more or less significant part of the body, or appear in the form of pimples. purulent and irritating localized on the face or arms or legs. Beyond the unsightly aspect of these manifestations and the discomfort which results from them, there is pain.
- eczema Among all skin diseases, eczema is the most common: this disease motivates up to 30% of dermatology consultations, reaching 15% to 30% of children and 2% to 10% of adults. Eczema cases have doubled or even tripled in the past 30 years.
- contact or allergic dermatitis which are characterized by lesions of eczema after contact of the skin with certain substances called allergens which can be chemical substances, clothes, sometimes metals.
- allergens can be chemical substances, clothes, sometimes metals.
- Eczema can appear after a few minutes or 3 to 10 days depending on the degree and time of exposure to the allergen.

- Atopic people often present, simultaneously or alternately, various allergic reactions, such as hay fever, hives, asthma or food allergies.
- lesions appear on the cheeks, forehead and scalp until they extend to the extension faces of the arms and legs and the trunk. They are characterized by dry and rough or oozing and crusty redness, which has the disadvantage of itching and irritation because often lesions of atopic dermatitis will predominate in the bending folds of the elbows and knees or even wrists.
- the lesions are located mainly on the face, neck and limbs. They are often thickened and sometimes purulent.
- Creams or ointments based on corticosteroids are applied to the areas to be treated, which reduces itching and inflammation. Creams and ointments that have a strong steroid effect are used to relieve significant irritation, but over a short period, because in the long term, they lose their effectiveness and can thin the skin.
- Antihistamines are also used against itching, but their action time is limited in time and requires several doses.
- Immunomodulatory drugs are also a remedy against the use of corticosteroids and have the effect of decreasing the activity of the immune system (therefore inflammation) with more or less side effects.

- the advantage is that a large area can be treated; it can affect the whole body or all or parts of the body, especially effective when the inflammatory disease is localized in different areas; this avoids using large amounts of cream.
- the treatment can be carried out in a bath for an exposure period ranging from 5 to 45 minutes and repeated more than once a day until the inflammatory symptoms disappear or improve.
- the treatment is more effective after two days and from 5 hours after exposure for fifteen minutes in a bath comprising the electrolysed water according to the method of the invention.
- a very high density of inflammation of the skin is observed in the foot, which subsides 5 hours after exposure in the bath, then two days after the bath, the inflammatory part appears be in the form of a crust still reddish but no longer causing itching conducive to forming crusts which will fade later.
