Which process uses galvanic current from the positive pole toward the negative to push an acidic product into deeper tissues?

• A. Cataphoresis
• B. Anaphoresis
• C. Desincrustation
• D. Iontophoresis

Answer: (A)

When electrical current is used to move substances into the skin, the direction and the charge of the ions being moved depend on the polarity of the electrode. Cataphoresis is the process where the current flows from the positive electrode toward the negative, driving positively charged, acidic ions into deeper tissues. This makes it the best match for pushing an acidic product deeper into the dermis. Anaphoresis, in contrast, involves moving substances associated with the opposite charge (often alkaline) using the negative pole. Desincrustation uses an alkaline preparation and the negative pole to soften surface sebum. Iontophoresis is the general term for driving ions into the skin with electric current, without specifying the ion’s charge or the direction.
