What is the main use of galvanic current in facial treatments?

• A. Drive active ingredients into the skin via iontophoresis.
• B. Exfoliate by scrubbing.
• C. Heat tissue.
• D. Tighten muscles.

Answer: (A)

The main use of galvanic current in facial treatments is to drive active ingredients into the skin through iontophoresis. Because galvanic treatment uses a constant direct current, the charged particles in serums or creams are pushed into the deeper layers of the epidermis and sometimes into the upper dermis. This enhances the delivery and effectiveness of active ingredients such as vitamins or antioxidants, making the products work more efficiently than surface application alone.

This modality differs from exfoliation by scrubbing, which is a physical, mechanical process that removes dead skin cells rather than promoting deeper ingredient penetration. It also doesn’t primarily heat tissue or tighten muscles; those effects come from different technologies or approaches. The beauty of galvanic iontophoresis is the controlled movement of ions into the skin, guided by the electrical field.
