What is cataphoresis?

Cataphoresis refers specifically to the process of the movement of positive ions to the negative pole, which is a key concept in both esthetics and electrotherapy. This technique is often used in electrolysis and facial treatments to enhance product penetration into the skin. By applying a positive current, the positive ions in a solution can be driven deeper into the skin, allowing for increased efficacy of the ingredients being used.

Additionally, cataphoresis plays a significant role in various facial treatments aimed at rejuvenation and hydration, as it facilitates the delivery of beneficial active ingredients found in cosmetics or serums directly to the targeted areas in the skin. This controlled movement of ions is essential for achieving specific skin care goals during a treatment.

The other options do not capture the unique aspect of cataphoresis correctly as they describe either the introduction of products through non-electrical means or implications that are not consistent with the definition of cataphoresis. Understanding this concept is vital for practitioners in ensuring they can effectively manipulate current to enhance skincare treatment outcomes.
