What characteristic defines galvanic current?

Galvanic current is characterized primarily as a direct current used in electrotherapy. This form of current flows in a single direction and is often applied in various beauty therapy treatments for its therapeutic benefits. In electrotherapy, galvanic current can facilitate iontophoresis, a technique that enhances the penetration of products into the skin by using electrical current. It helps to improve the overall effectiveness of certain treatments, particularly for conditions like acne or to deliver active ingredients transdermally.

Understanding the distinction between direct and alternating currents is vital in beauty therapy. Direct current remains constant and flows in one direction, while alternating current periodically reverses its direction, which is not a characteristic of galvanic current. Additionally, interrupted current and residual current refer to other types of electrical currents that do not describe the continuous and uniform nature of galvanic current. Therefore, the definition of galvanic current aligns with the notion of it being a direct current in the context of electrotherapy.
