What is the primary function of galvanic current in electrolysis?

The primary function of galvanic current in electrolysis is to promote hair removal. Galvanic current facilitates the process of disabling hair follicles by delivering a steady, low-level electrical current to the targeted area. This current helps to break down the biochemical structure of the hair follicle, making it unable to regrow hair. The method, often utilized in electrolysis treatments, ensures that the hair is permanently removed by altering the follicle's ability to produce hair in the future.

While other functions related to galvanic current, such as heating or producing chemical reactions that create bubbles, can occur, they are secondary to the primary goal of hair removal in this specific context. Hence, the correct choice reflects the essential purpose of galvanic current in electrolysis treatments.
