How does the negative pole affect the skin?

The function of the negative pole in electrolysis or galvanic treatments primarily involves its interaction with the skin's properties. When the negative pole is applied, it can create irritation to the nerve endings, often leading to an increase in blood flow and redness in the treated area as part of the body's natural response to the stimulation.

This mechanism can indeed promote a warming sensation and enhance the treatment area, but its primary effects align with irritation and stimulation of the nerves. This is why it is seen as irritating, which can help to facilitate various skin treatments, such as helping in the extraction of impurities when using galvanic current for facial treatments. Understanding this function clarifies how specific electrical modalities impact skin conditions and beautification procedures.

While other effects like hydration or soothing are generally associated with other currents or treatments, the negative pole's distinct role is recognized for its stimulating and potentially irritating characteristics, particularly in its immediate effect on the skin's surface and vascular response.
