Final answer:
Iontophoresis is the process of infusing an acidic product into tissues using galvanic current, similar to electron flow in a galvanic cell where chemical energy is converted into electrical energy.
Step-by-step explanation:
The process of infusing an acidic (positive) product into deeper tissues using galvanic current from the positive pole to the negative pole is known as iontophoresis.
In the context of a galvanic cell, the described action involves the movement of ions under the influence of an electric field to facilitate chemical reactions.
Galvanic cells, also known as voltaic cells, convert chemical energy into electrical energy to do work.
For example, a galvanic cell can be created using a copper strip in a solution of Cu²⁺ ions and a zinc strip in a solution of Zn²⁺ ions.
These strips serve as electrodes and are connected by a wire, allowing for the flow of electrons due to the potential energy difference.
In a skincare context, iontophoresis uses a similar principle with electrodes and a galvanic current to transport substances into the skin.
