The galvanic or multiple-needle process of electrolysis uses what type of electrical current?

The galvanic or multiple-needle process of electrolysis utilizes direct current. This type of current flows steadily in one direction and is essential for the process of electrolysis, where a chemical reaction occurs at the anode and cathode. In the context of hair removal, direct current facilitates the breakdown of the hair follicle’s structure, leading to the effective removal of hair.

The other types of current, such as oscillating, high frequency, and alternating current, do not serve the same purpose in electrolysis. Oscillating current usually refers to a current that changes direction periodically but is not used in this context. High frequency is often associated with treatments such as skin rejuvenation or antiseptic procedures, rather than the permanent hair removal techniques. Alternating current, which periodically reverses direction, is more commonly employed in other types of electrical therapies but not in the galvanic process critical for efficient hair removal through electrolysis.
