What is the function of the high-frequency current in skin treatments?

1. Moisturizing the skin

2. Enhancing exfoliation

3. Stimulating the scalp

4. Stimulating tissue metabolism

The correct answer is: Stimulating tissue metabolism

The function of high-frequency current in skin treatments primarily involves stimulating tissue metabolism. High-frequency treatment uses an electrical current that generates heat within the skin's layers, promoting increased blood circulation, cell turnover, and enhanced metabolic activity. This stimulation accelerates the healing process, improves oxygenation, and can lead to better absorption of topical products, thereby contributing to healthier skin. While moisturizing the skin and enhancing exfoliation are important aspects of skincare, they are not the primary functions served by high-frequency current. Moisturizing typically involves the use of hydrating products, and exfoliation is usually achieved through mechanical or chemical means rather than through electrical stimulation. Although high-frequency can have some benefits for the scalp, such as improving circulation, its primary role in skincare is to increase metabolic activity within the tissues of the face and other areas being treated.
