The galvanic current is named after Luigi Galvani, who spent his life studying electric currents. In 1791, he used these electric currents to twitch the legs of a frog. The results of his experiment led scientists to discover further insight into the uses of the galvanic current. Galvanic treatments have been used for more than 50 years primarily in Europe and now are gaining popularity in the United States.
Note: There are 2 types of galvanic treatments, estheticians, such as I can provide.
1: Desincrustation- This deep cleanses, removing oil from the skin (via extractions) and removes skin blockages.
2: Iontophoresis- This introduces a water soluble substance (such as a mask) directly into the skin.“HOW GALVANIC WORKS
The Galvanic current which flows through the skin, forms a circuit between the active electrodes and the indifferent electrode, causing active substances to pass into the epidermis of the skin, on the galvanic charge. The active electrodes on the galvanic charge, can be either positive or negative, and the substances pushed into the skin will be positively or negatively charged.
If the substance has positive ions, the active electrode must also be positive, so that they will repel each other, therefore the galvanic charge will push/pull the substance deeper into the skin towards the indifferent electrode, which is held in the clients hand,(or placed behind the shoulder) to complete the circuit. The negative electrode, is used with a gel containing negative ions, the indifferent electrode is always used to complete the circuit.
Important terms for Galvanic Treatments:
Anaphoresis: The movement of negative ions to the positive pole.
Cataphoresis: The movement of positive ions to the negative pole.
Anode: Positive pole.
Cathode: Negative pole.
Anions: Ions with a negative charge.
Cations: Ions with a positive charge.
Active Electrode: The working electrode applied to the face during treatment.
Indifferent Electrode: non working electrode held in the hand to complete the circuit.
Ion: An atom carrying an electrical charge.
Ionization: Use of active ions or electrically charged elements in treatments.
Milliamp meter: Measures the amount of galvanic current used and also indicates the level of of the skins resistance.
Saponification: ‘Soaping’ or cleansing of the skin using a negative charge with a saline solution or desincrustation lotion. (This is the most interesting to me, the natural chemical reaction of the skin is to saponify!)GENERAL EFFECTS OF GALVANIC CURRENT
Galvanic increases the circulation, acts as a tonic to the skin, improving its colour.
Galvanic is Soothing; Fluid in the tissues is drawn to the negative pole, which is called electro-osmosis. When the positive pole is used over an area, waste products and fluid in the tissues is drawn away from the area, relieving tension.
Galvanic causes Relaxation; Warmth is produced inside the tissues, promoting relaxation.
Galvanic plumps up the tissues, reducing fine lines and wrinkles.”
