What kind of electrical current does galvanic use?

Galvanic current specifically refers to the use of direct current (DC) in various applications, particularly in electrotherapy and galvanic skin treatment. This type of current involves a constant flow of electrical charge in one direction, which is essential for facilitating chemical reactions in the skin or tissues during treatments. In the context of galvanic therapy, direct current is used to push active ingredients deeper into the skin or to promote certain healing processes. This differentiates it from alternating current (AC), which changes direction periodically and is not suitable for the same therapeutic applications as galvanic treatments.
