What is the process called that involves forcing acidic substances into deeper tissues using galvanic current?

1. Iontophoresis

2. Cataphoresis

3. Electrophoresis

4. Microdermabrasion

The correct answer is: Cataphoresis

The process of forcing acidic substances into deeper tissues using galvanic current is referred to as cataphoresis. This technique utilizes the principles of iontophoresis, where ions are pushed into the skin tissue with the help of an electrical current. Cataphoresis specifically relates to the movement of positively charged ions (cations) into the tissue, which is particularly effective for delivering acidic substances that can offer therapeutic benefits, such as deeper hydration or other skin benefits. In the broader context, while iontophoresis covers this method generally, cataphoresis is a specific application focused on acidic (positive) substances. Other options like microdermabrasion are unrelated, as they involve physical exfoliation and do not use electrical currents or ion movement. Electrophoresis is a more general term that can refer to the migration of charged particles under an electric field but does not specifically denote the application of acidic substances into the skin. Understanding cataphoresis allows estheticians to utilize galvanic current effectively for skin treatments, emphasizing the significance of electrical modalities in skincare.
