Which of the following statements is true regarding high frequency and galvanic current?

The statement that high frequency and galvanic current can be delivered simultaneously, separately, or after each other is correct. In electrolysis and electrotherapy, these two types of current serve different purposes and can complement each other effectively.

High frequency currents are typically used for their disinfectant properties and to promote healing, while galvanic currents are utilized for their electrochemical effects, such as iontophoresis, which helps in delivering substances through the skin.

The versatility of using these currents together or at different times allows practitioners to tailor treatments based on the specific needs of the client. For instance, one might use galvanic current first to prepare the skin and then follow up with high frequency for its therapeutic benefits.

This combined or sequential approach can provide a more comprehensive treatment plan, addressing various skin conditions or hair removal needs, thereby enhancing the overall efficacy of the electrolysis procedure.
