What are the two most common types of electrodes used with the galvanic machine?

1. Sponge and spray

2. Flat and roller

3. Pointed and curved

4. Round and oval

The correct answer is: Flat and roller

The two most common types of electrodes used with the galvanic machine are flat and roller electrodes. Flat electrodes are typically used for larger treatment areas and provide a consistent distribution of the electrical current across the skin, enhancing the penetration of serums or solutions used during treatments. These electrodes are effective for treating flat surfaces and can cover a broader area, making them ideal for procedures like deep cleansing or facial treatments. Roller electrodes, on the other hand, are designed to facilitate movement across the skin easily. They are often used in a massaging motion, allowing for the stimulation of blood circulation and lymphatic drainage during the treatment. The rolling action can enhance the treatment experience by providing a soothing effect while still delivering the necessary electrical currents. The combination of these two types leads to effective results in various esthetic procedures, making them the most common choices in galvanic treatments. Other electrode shapes listed may serve specific functions or be used in particular contexts, but flat and roller electrodes are foundational for general use in esthetic practices with galvanic machines.
