What does cataphoresis refer to in skincare?

Cataphoresis in skincare refers specifically to the process of infusing a positive (acid) product into the skin using electric current. This technique utilizes a direct current to drive positively charged substances into deeper layers of the skin. The method involves the use of electrodes, where the positive electrode is applied to the skin, and as the electric current passes through, the positive ions from the solution move into the skin, enhancing product absorption and improving the efficacy of the treatment.

This method is often employed in facial treatments to deliver various beneficial ingredients, such as vitamins and antioxidants, which can provide hydrating, soothing, and rejuvenating effects on the skin. Understanding the role of electrical currents in facilitating deeper penetration of active ingredients is essential in skincare practices, as it allows professionals to maximize the benefits of their treatments.

In contrast, the other choices do not accurately describe cataphoresis—negative (alkaline) product infusion refers to a different process, heat application relates more to devices like steamers or LED therapies, and the removal of impurities typically pertains to methods like exfoliation or extraction rather than the electric infusion technique.
