What is one effect of cataphoresis on the skin?

Cataphoresis is a process used in electrotherapy that involves the application of a direct electric current to the skin, which helps to enhance the penetration of products into the skin. When cataphoresis is applied, it creates an acidic environment, which aids in the absorption of certain skincare products. This acidic condition can promote effective delivery of active ingredients deeper into the skin, effectively treating conditions such as hyperpigmentation or dehydration. The focus on enhancing penetration through an acidic medium is why this option is the correct answer, highlighting its importance in dermatological treatments and cosmetic procedures.
