The negative pole of the galvanic current machine is typically associated with specific benefits during facial treatments, particularly its ability to stimulate nerves. When the negative electrode is applied to the skin, it produces a reaction that can enhance blood circulation, leading to increased nerve stimulation. This stimulation can help promote skin vitality and overall tone, making it a valuable technique in enhancing the skin's responsiveness during treatments.

While other effects, such as calming redness, softening the skin, or hydrating the skin, may also be achieved with different methods or modalities, the primary action of the negative pole in galvanic treatments is rooted in its nerve-stimulating properties. Understanding this function helps estheticians effectively utilize galvanic current in their practice to achieve desired treatment outcomes.
