What is the process of infusing a positive (acid) product into the skin using electric current called?

The correct process for infusing a positive (acid) product into the skin using electric current is called cataphoresis. This method involves the use of galvanic current, which drives positively charged substances into the skin. The process leverages the principle that like charges repel, allowing for deeper penetration of active ingredients.

In cataphoresis, the esthetician applies a positively charged electrode to the skin while the product has a positive charge, effectively enhancing the absorption of the product into the underlying layers. This technique is especially beneficial for treating certain skin conditions, as it helps to deliver antioxidants and other active ingredients directly into the skin.

While anaphoresis and iontophoresis are related techniques in electrotherapy, they have different applications. Anaphoresis typically deals with the infusion of negatively charged substances, and iontophoresis is a broader term that encompasses both cataphoresis and anaphoresis. Electrolysis, on the other hand, is a hair removal technique that utilizes direct current for permanently removing hair, and is not focused on product infusion. Understanding these distinctions clarifies why cataphoresis is the specific correct answer for infusing a positive product.
