As people have become more concerned with the effects of pollution on the skin, their interest in scientific skin care has been renewed. Due to this new interest on the part of the public, machines have been re-introduced as a new concept in professional skin care treatments.
The Galvanic Current is a constant and direct current ( D.C ) rectified to a safe, low-voltage level. Chemical changes are produced when the current is passed through certain solutions containing acids and salts. Chemical effects are also produced when a galvanic current is passed through the tissues and fluids of the body.
The Galvanic Machine has two important functions during a facial treatment. Its main function is to introduce water soluble products into the skin, This process is called the iontophoresis. When using galvanic current there are two poles, a negative ( - ) and a positive ( +).
