Which type of current is primarily used in deep tissue treatments?

1. Pulsed current

2. Galvanic current

3. High-frequency current

4. Sine wave current

The correct answer is: Galvanic current

Galvanic current is primarily used in deep tissue treatments due to its ability to facilitate iontophoresis, which is the introduction of ionic substances into the skin through the use of electrical currents. This type of current generates a chemical effect in the tissues, allowing for deeper penetration of products that can aid in muscle relaxation and tissue repair. Additionally, galvanic current can promote increased circulation and help in the healing process by enhancing nutrient delivery to the cells. In deep tissue treatments, the focus is often on achieving deeper effects within the skin and muscles, which galvanic current can effectively provide due to its electrochemical properties. Other currents, while beneficial in various modalities, do not penetrate the tissues in the same manner as galvanic current does. This distinction highlights the specific applications of each type of current in esthetic practice.
