Wisconsin Esthetics State Board Practice Test

Which type of current produces a mechanical, non-chemical reaction?

1. Galvanic current

2. Indirect faradic current

3. Faradic current

4. Sinusoidal current

The correct answer is: Faradic current

The type of current that produces a mechanical, non-chemical reaction is Faradic current. This form of alternating current is primarily used in muscle stimulation treatments. When applied to the skin, it generates muscle contractions through its specific waveform that mimics the body’s natural nervous impulses. This mechanical action helps in improving blood circulation, promoting muscle tone, and aiding in the enhancement of skin texture, all without causing any chemical reaction. Understanding the nature of Faradic current is essential in esthetics, particularly when dealing with treatments aimed at muscle stimulation and toning. This current is distinct from others, such as galvanic current, which induces chemical reactions in the tissues, or sinusoidal current, which is more similar in function to Faradic but differs in the frequency and resulting efficacy for specific treatments. Each type of current has its own unique applications, making it crucial for practitioners to be knowledgeable about their effects.
