Which electrode does the client hold during the process of deincrustation?

During the process of deincrustation, the client holds the positive electrode. This choice is significant because deincrustation is typically performed using galvanic current, which utilizes positive and negative electrodes to help soften and dissolve sebum, dirt, and dead skin cells in the pores. The positive electrode has the effect of making the skin tissue more alkaline, which is conducive to breaking down oils and impurities.

In the context of electrical currents, the positive electrode is often used in conjunction with a negative electrode, which is held by the therapist or applied to the treatment area. The primary role of the positive electrode that the client holds is to assist in the conductivity of the current, enabling the treatment to penetrate effectively and achieve its intended results.

Other options like the neutral electrode, which does not carry current in the same way, or a grounding electrode, typically used for safety purposes to prevent electrical shock, are not relevant to the process of deincrustation. Therefore, the distinction of the positive electrode's role is crucial for understanding its function in the treatment.
