Which statement describes the positive pole in facial galvanic treatment?

• A. Open the pores to enable penetration of active ingredients.
• B. Introduces acid preparation into the skin.
• C. Stimulates blood and lymph circulation.
• D. Introduces alkaline preparation into the skin.

Answer: (B)

The positive pole is the anode in facial galvanic treatment, and it creates an acidic environment at the skin surface. When the positive electrode is in contact with a solution, electrolysis produces hydrogen ions (H+), lowering the surface pH. This acidic condition drives the acid preparation into the skin via iontophoresis, making the positive pole the one that introduces acid into the dermal layers.

While galvanic current can influence overall circulation, that effect isn’t specific to the positive pole. Introducing an alkaline preparation would be associated with the opposite pole, which generates hydroxide ions and raises pH.
