Which type of electric current is classified as galvanic?

Galvanic current is defined as a type of direct current (DC) that is used in various therapeutic and skin care treatments. This current flows in one direction and is characterized by its ability to drive ions into the skin through a process called iontophoresis. The consistent and uninterrupted flow of direct current allows for a stable environment needed for certain cosmetic and medical procedures, such as delivering medications or enhancing the effects of skincare products.

In contrast, alternating current (AC) changes direction periodically, which is not suitable for the specific therapeutic effects associated with galvanic treatments. Faradic current, another form of electrotherapy, involves alternating currents that stimulate muscle contractions, thereby differing significantly from galvanic current's application. Ripple current typically refers to a type of non-constant waveform, which does not have the continuous flow that galvanic current possesses. Thus, identifying galvanic current with direct current is crucial for understanding its application in beauty and healthcare practices.
