How does Galvanic electrolysis work?

Galvanic electrolysis operates using direct current to induce a chemical reaction that ultimately leads to the destruction of the hair follicle. This method specifically relies on the application of a low-voltage direct current, which passes through the skin and into the hair follicle. The electric current interacts with the saline solution present in the follicle, leading to the electrochemical process of ionization. This process produces sodium hydroxide, a caustic agent that effectively destroys the hair matrix and surrounding tissue, preventing future hair growth.

The choice emphasizing heat and high-frequency current relates more to methods like thermolysis or blend techniques, which involve different principles of operation. Conversely, the other options involving laser technology do not pertain to galvanic electrolysis, as lasers utilize light energy rather than electrical currents to target hair follicles. Therefore, selecting the option that states galvanic electrolysis uses direct current to create a chemical reaction accurately reflects the core principle behind this method.
