During a facial treatment, the positive pole of the galvanic current machine may produce:

When using a galvanic current machine during a facial treatment, the positive pole is associated with producing an acidic reaction. This reaction occurs because the positive pole, or anode, releases hydrogen ions, which can lower the pH of the tissue in its vicinity, resulting in an acidic environment.

This acidic reaction can be beneficial in certain facial treatments, such as those aimed at softening the skin or enhancing the penetration of products designed to treat specific skin concerns, like anti-aging or hydration. The formation of this acidic environment can also help to tighten and tone the skin, enhancing the overall appearance and texture.

In contrast, the negative pole produces an alkaline reaction, which has its own set of benefits, like promoting skin hydration and deep cleansing. Understanding these reactions is crucial for estheticians to provide effective treatments tailored to the client's skin needs.
