What is considered a galvanic treatment using a very low level of electrical current?

Electrolysis
Laser hair removal
Microcurrent
Ultrasonic therapy

The correct answer is: Electrolysis

The correct answer is electrolysis. Electrolysis is a method that uses a galvanic current, which is a very low level of electrical current, to remove hair permanently. The process involves inserting a fine needle into the hair follicle and applying the current, which causes a chemical reaction that destroys the hair root. In contrast, while microcurrent therapies also use electrical stimulation, they operate typically at a higher frequency and are mainly aimed at muscle toning and skin rejuvenation rather than permanent hair removal. Laser hair removal utilizes concentrated light beams, not electrical current, to target hair follicles. Ultrasonic therapy involves sound waves for various skin treatments and does not utilize electrical currents in the same way. Understanding these processes clarifies why electrolysis is specifically associated with the galvanic treatment using low electrical currents.
