Which current forces a water-based soluble solution into the skin?

• A. Alternating current
• B. Direct current
• C. Galvanic current
• D. High-frequency current

Answer: (C)

The correct choice involves galvanic current, which is specifically designed to force a water-based soluble solution into the skin through a process known as iontophoresis. This method utilizes a direct electrical current to drive charged particles, such as ions from the soluble solution, into deeper layers of the skin. In this process, the positive and negative terminals of the galvanic device cause the ions in the solution to move through the skin membrane, allowing for enhanced absorption of the active ingredients. The ability to deliver nutrients or therapeutic agents directly into the skin makes galvanic currents particularly useful in aesthetic and therapeutic treatments. Other currents, although they have their own beneficial skin effects, do not specifically force a soluble solution into the skin in the same way. For instance, alternating current is typically used for different therapeutic applications, while high-frequency current primarily focuses on stimulating the skin and killing bacteria, rather than delivering substances into the skin's deeper layers. Direct current can also have various applications, but it is not primarily used for iontophoresis in this context.
