What is the purpose of cataphoresis in skin treatment?

• A. To open pores
• B. To help skin pH return to normal
• C. To provide hydration to the skin
• D. To exfoliate the skin

Answer: (B)

Cataphoresis is a technique that involves the application of an electrical current to deliver substances into the deeper layers of the skin. One of its primary purposes is to help restore the skin’s pH balance. This is important because maintaining an optimal pH level is crucial for skin health. When the skin’s pH is balanced, it can function properly, enhancing its overall appearance and resilience against irritants and infections.

Using cataphoresis, practitioners can introduce specific ingredients that can help neutralize the skin’s acidity or alkalinity, effectively supporting the skin's natural barrier functions. This method is not primarily about opening pores, providing hydration, or exfoliating; rather, it focuses on the internal balance of the skin, which is foundational for other treatments to be effective.
