In which treatment is the use of cathode as the active electrode particularly relevant?

In desincrustation, the use of the cathode as the active electrode is particularly relevant due to its role in the process of galvanic treatments. During desincrustation, a negative galvanic current is applied to the skin using the cathode, which helps to soften and dissolve sebum and impurities within the pores. This process enhances the skin's ability to absorb products, making it an effective pre-treatment step for deeper cleanses or extractions.

The negative charge of the cathode helps to break down the hardened sebum and facilitates the elimination of impurities, enabling a deeper clean that is especially beneficial for oily or acne-prone skin. Additionally, the alkaline effect produced by the negative electrode aids in softening the skin’s tissue, making it easier to remove debris from the pores.

While moisturizing treatments, exfoliation, and facial toning techniques serve important purposes in skincare, they do not primarily rely on the cathode for their active effects. Moisturizing treatments focus on hydration, exfoliation concentrates on sloughing off dead skin cells, and facial toning generally involves improving skin firmness without the direct influence of a cathodic charge like that seen in desincrustation.
