Direct current is used for galvanic therapy for what purpose?

• A. Galvanic treatment and galvanic electrolysis.
• B. Aromatherapy.
• C. Microdermabrasion.
• D. Laser therapy.

Answer: (A)

Direct current in galvanic therapy is used to create controlled chemical changes in the skin and hair follicle. The steady DC causes electrochemical reactions at the treatment area, producing localized acidity or alkalinity (acid at one electrode, alkali at the other). This helps break down and dissolve impurities, enhances cleansing, and, with iontophoresis, drives active ingredients into the skin. In galvanic electrolysis, the same current chemically disrupts the hair follicle to destroy it. So the purpose is to perform galvanic treatment and galvanic electrolysis, not to power aromatherapy, microdermabrasion, or laser therapies.
