Which type of electrode is used in cataphoresis?

Negative
Neutral
Positive
Variable

The correct answer is: Positive

Cataphoresis is a skincare technique that involves using a positive electrode to introduce positively charged ions of an active ingredient into the skin. By applying a positively charged electrode (anode) to the skin during cataphoresis, the positively charged ions in the skincare product are repelled from the electrode and driven into the skin. This process enhances penetration and absorption of the active ingredients, leading to better results. Therefore, the correct answer is "C. Positive." Neutral electrodes are not typically used in cataphoresis as they do not contribute to the ionization of the active ingredients. Negative electrodes are used in other skincare techniques like anaphoresis, which involves introducing negatively charged ions into the skin. Variable electrodes are not a specific type used in cataphoresis but may be used for different purposes in skincare treatments.
