During cataphoresis, which electrode does the client hold?

In cataphoresis, which is a part of galvanic electrical treatments in esthetics, the client holds the negative electrode. This process involves the use of direct current to introduce products into the skin, typically involving an acidic or an alkaline reaction based on the electrode’s polarity.

When the client holds the negative electrode, this allows for the ions in the product being applied to be pushed into the skin effectively. The negatively charged ions are attracted to the positive pole (the electrode used by the esthetician), while the neutral electrode can typically be connected to the larger electrode that delivers the current. This method enhances product penetration and promotes various skin benefits, such as improved hydration and reduced inflammation.

In this context, holding the negative electrode is crucial for facilitating the desired physiological reactions in the skin, making the client's role integral to the efficacy of the treatment. The positive electrode, neutral electrode, and ground options do not align with the functionality required during cataphoresis, as their roles differ in electrical treatments. The positive electrode, for example, would be used in situations where the current needs to attract negatively charged ions, while a neutral or ground electrode serves different purposes in ensuring the safety and efficacy of the process.
