What are the two poles in galvanic current?

• A. Positive (Anode) and Negative (Cathode)
• B. Positive (Cathode) and Neutral
• C. Positive and Negative only
• D. Anode only

Answer: (A)

In galvanic current, the two poles are referred to as the anode and cathode, which are critical components in any electrochemical process involving direct current. The anode is the positive pole where oxidation occurs, leading to the release of electrons. Conversely, the cathode is the negative pole where reduction takes place, allowing electrons to be accepted.

Understanding these roles is essential for estheticians who use galvanic procedures in skin treatments. For instance, the anode can help in the removal of impurities or dead skin cells by promoting the chemical reaction that leads to these processes, while the cathode can enhance hydration and product penetration through its different functions in the galvanic treatment.

The other choices do not accurately represent the fundamental principles of galvanic current. The mention of “neutral” or only referencing a single pole does not align with the established definitions and roles of anode and cathode in galvanic applications. This knowledge is vital for estheticians to safely and effectively utilize electrical modalities in their practices.
