The process of applying a negative product during iontophoresis is referred to as what?

The process of applying a negative product during iontophoresis is referred to as anaphoresis. This technique involves the use of a negative electrical charge to push negatively charged ions of a product into the skin. When an electric current is passed through the skin, it helps facilitate the penetration of the product, enhancing its efficacy.

Anaphoresis is particularly useful for delivering products that are designed to treat specific concerns, such as acne or oily skin, where a negative charge can help reduce inflammation or excess oil production. This method contrasts with cataphoresis, which involves a positive charge and is used to introduce positively charged substances into the skin. Understanding the specific techniques and their applications is essential for effective treatment in the field of esthetics, making it important to recognize the distinction between these processes.
