Wisconsin Esthetics State Board Practice Test

In esthetics, what does a high amperage in galvanic current assist with?

1. Creating an electrochemical effect

2. Reducing muscle tension

3. Heating the tissue

4. Improving blood flow

The correct answer is: Creating an electrochemical effect

A high amperage in galvanic current assists with creating an electrochemical effect, which is a fundamental principle in electrotherapy used in esthetics. The galvanic current produces a direct current that leads to the transfer of ions, enabling chemical reactions to take place at the electrodes. This process can be beneficial for various skin treatments, such as iontophoresis, where positive and negative ions are introduced into the skin to enhance product absorption or to stimulate specific biological responses. While other aspects of galvanic treatments do touch on benefits like improving blood flow, reducing muscle tension, or heating tissue, the primary function of high amperage is heavily centered on inducing desired chemical reactions through electrolysis, thus making the creation of an electrochemical effect the most pertinent reason for its use in esthetics.
