What effect does cataphoresis using the anode polarity have on the skin?

When cataphoresis is performed using the anode polarity, it generally results in reduced erythema, which is the redness of the skin caused by increased blood flow. The anode has a soothing effect on the skin, and its application tends to calm inflammation, which can lead to a decrease in redness and irritation. This polarity promotes a more stable environment for skin tissues, allowing for healing and reducing the likelihood of inflammatory responses that cause erythema.

While the other effects, such as increasing hydration or darkening the skin, can occur with different techniques or polarities, they do not apply specifically to cataphoresis with anode polarity. In this case, the primary effect is the reduction of erythema, making the skin appear less irritated.
