The method of physiotherapy, which uses the action of a pulsed current of high voltage and frequency, but of low strength, is called darsonvalization. This method of exposure was discovered in 1891 by the French physiologist-scientist Jacques d'Arsonval. He revealed the beneficial effect of such a current on human he alth. The method is applicable in the treatment of skin diseases, genital organs, nervous system.
The first apparatus for darsonvalization was created 120 years ago. Its use has proven effective as a treatment, and it has become the most widely used. In the 80s, such a device was available in any physiotherapy room in the USSR. Darsonvalization was included in the treatment regimen for many diseases, but it was especially widely used in cosmetology.
How the method works
High-frequency currents can irritate the sensitive nerve endings in the skin, and thus they activate blood circulation. Vessels at first sharplyspasm, and then expand for a long time. Nutrition of cells and their respiration improve, local immunity is activated. This is due to the release of prostaglandins and cytokines. Increased skin turgor. Leukocytes begin to intensively destroy pathogenic microorganisms, which speeds up recovery many times over.
Darsonval acts in a variety of ways:
- Contact method - the electrode slides directly over the skin.
- Non-contact method - distance to the skin is a few mm. With this arrangement of the electrode, there may be a different distance to the skin. At a distance of 2-3 mm, a whole sheaf of spark discharges occurs - a slip of cold sparks. They also irritate the nerve endings, but their excitation is transmitted to the spinal cord. After that, diseased organs react and pain sensations are blocked - this is a reflex reaction.
- Point method of application - the electrode is above the skin at a distance of up to 1 cm - the sparks are long and accompanied by a crack. This method removes warts.
- Bactericidal effect - charged ions strike at microbes and they die. Electrical discharges produce ozone and nitrogen oxides (remember the air during a thunderstorm). Ozone itself has a bactericidal effect. Due to this effect, small pimples and pustules dry up, and large, not ripe abscesses open in the next day.
During a darsonvalization session, the patient does not feel any discomfort at all. Only a slight warmth is felt.
Indications for darsonvalization
Darsonval is shown in the following cases:
- Pathologies of the peripheral nervous system: paresthesia, neuralgia, consequences of neuritis, radiculitis and osteochondrosis.
- CNS disorders: migraine, neuroses, insomnia, dystonia, enuresis, neurodermatitis.
- Skin pathologies: acne, diathesis, dermatosis, inflammatory infiltrates, increased activity of the sebaceous glands.
- Inflammation of the subcutaneous fat, known as cellulitis.
- With such circulatory disorders as: varicose veins, trophic ulcers, fungal skin lesions.
- Diseases of ENT organs: perceptual hearing loss, stomatitis, rhinitis, sinusitis.
- Genital diseases: impotence, prostatitis, inflammation of the genitals, vaginal dryness.
Effects of darsonvalization
In addition to improving the condition of the skin, increasing its turgor and local immunity, allergic rashes and itching decrease, a bactericidal and anti-inflammatory effect appears, hair growth is stimulated by improving the nutrition of hair follicles. It should be noted that with hair, the result is so pronounced that there may be a side effect in the form of increased vegetation on the skin.

- bleeding;
- pregnancy (the risk of congenital abnormalities in the fetus due to the electromagnetic field).
Relative contraindications:
- damage to the skin in the affected area;
- pain on electrodes;

Side effects of the procedure
Basically, this is an increased growth of facial hair and the risk of a recurrence of a stroke if contraindications are not observed. Darsonvalization has now become available at home if you buy a portable device.

Sores and open wounds should be covered with a clean gauze pad. For better glide of the electrode, it is good to sprinkle the skin with talcum powder. With vellus facial hair, talcum powder will also help to avoid excess hair growth.
When using darsonval, dry skin may increase. In this case, it is better to lubricate it with cream after the procedure.
When using an electrical appliance for the first time, there is often a fear of getting an electric shock. A good machine will rule this out. But if the electrodes are damaged, for example, they can create an uncontrolled discharge.
Therefore, if the electrode has a crack, it cannot be used and must be replaced. Specialized repair shops can be found online.
Instructions for use
The "Spark ST-117" darsonval manual gives a step-by-step guide to use.
- When connecting to the mains, make sure that there is no damage or dirt on the device.
- The discharge force regulator must be in the “Off” position.
- Next, you need to insert the desired electrode into the housing base,but without drastic effort. It should stick well. Only then can the device be connected to the network.
- First make sure that the device is working - for this, set the regulator to the middle position. An orange or purple glow should appear.
- Now turn off the device. If the glow does not appear at the end of the nozzle, try to force the ionization again. To do this, the regulator must be turned to the right to the extreme maximum position (max), and the electrode should be applied to the metal surface. It can be anything, but it must be grounded (but do not touch it).
- Discharge should appear within 5 minutes. If the glow still does not appear, the device must be taken in for repair - it is faulty.
- If everything is fine - bring the electrode to the problem area, but do not apply it to the skin. Then you need to slowly turn the regulator knob until a slight tingling sensation appears. Now you can work - the device is ready. It is also necessary to change nozzles when the device is unplugged.
- After the end of the procedure, the electrodes must be wiped with a cotton swab with alcohol. In extreme cases, wipe with a well-wrung cloth after soaking in detergent (neutral).
- Dry the device, pack in a case. Perform all manipulations when disconnecting from the network.
