Which of the following machines have two positive electrodes called an anode?

The correct answer relates to the galvanic machine, which utilizes two positive electrodes known as anodes in its operation. Understanding the function of these electrodes is crucial. In galvanic treatments, the anode plays a pivotal role in facilitating chemical reactions in the skin when an electrical current is applied. This process can help in detoxifying the skin, enhancing product penetration, and improving overall skin health.

The concept of having two positive electrodes, or anodes, distinguishes the galvanic treatment from other modalities. For instance, ultrasonic devices typically use sound waves for various skin treatments without involving anodes or electrical currents in the same manner as galvanic machines. Similarly, microdermabrasion focuses on physical exfoliation and does not rely on electrodes. Lasers utilize a form of light energy and have different electrode configurations depending on the type of laser, further differentiating it from the galvanic approach. Understanding the unique functions and characteristics of these devices is essential for anyone studying cosmetology and aesthetics.
