What is the nature of a galvanic current?

Galvanic current is characterized as a direct current (DC). This type of electrical current flows continuously in one direction, which distinguishes it from alternating current (AC), where the current periodically reverses direction. In the context of esthetics and skincare, a galvanic current is often used in various treatments, such as iontophoresis, where it facilitates the penetration of products into the skin. The direct nature of the current allows for a steady flow of electrons, which can create chemical reactions within the tissues, enhancing efficacy in therapeutic applications. Understanding its nature is crucial for estheticians to effectively employ galvanic treatments and achieve desired results for their clients.
