Cataphoresis involves applying a positive (acid) product into the skin during a facial treatment. This process helps in facilitating product penetration by using an electric current to ionize the acid product, allowing it to be absorbed more effectively into the skin. This technique is commonly used to treat specific skin concerns and enhance the overall effectiveness of the facial treatment. The other options are not correct because cataphoresis specifically involves the use of a positive (acid) product for skin penetration, rather than a neutral or negative product or softening the follicles.
