What is the role of galvanic current in skincare treatments?

1. Enhancing muscle tone

2. Facilitating product absorption

3. Providing hydration

4. Removing hair

The correct answer is: Facilitating product absorption

The role of galvanic current in skincare treatments primarily revolves around facilitating product absorption. This type of current operates through a process called iontophoresis, where the electric current helps to drive active ingredients deeper into the skin. This is particularly beneficial for treatments that involve serums or other topical products that are designed to address various skin concerns. By utilizing galvanic current, estheticians can enhance the efficacy of these products, ensuring that the beneficial ingredients penetrate the skin more effectively than they would with just topical application alone. This not only maximizes the benefits of the ingredients but also can lead to improved results for the client. Other options, like enhancing muscle tone or providing hydration, do not directly relate to the primary function of galvanic current. While galvanic treatments may contribute to skin health in an indirect way, their main focus remains on the improved absorption of skincare products. The option regarding hair removal pertains to different technologies altogether, such as laser or electrolysis, and does not connect to the function of galvanic current in skincare.
