Final answer:
Electrolysis is the process that uses galvanic current to enable water-soluble products to penetrate the skin.
Step-by-step explanation:
The process that uses galvanic current to enable water-soluble products to penetrate the skin is called electrolysis. In electrolysis, an external voltage is applied to drive a nonspontaneous reaction. This process has various applications, including the production of pure metals from metallic compounds, the electrolysis of brine to obtain chlorine and sodium hydroxide, and the generation of oxygen in water electrolysis for spacecraft and nuclear submarines.
