What is a primary mechanism through which Tesla high-frequency currents work?

1. Destruction of surface bacteria

2. Hydration of the skin

3. Closure of pores

4. Reduction of puffiness

The correct answer is: Destruction of surface bacteria

Tesla high-frequency currents primarily work through the destruction of surface bacteria. This therapeutic technique utilizes high-frequency electrical currents that generate heat when applied to the skin, creating an antimicrobial effect. The high-frequency oscillations produce ozone, which has properties that can kill bacteria and prevent infections, making it particularly effective for treating acne and other skin conditions where bacterial presence is an issue. The method also leads to improved circulation and can aid in further skin healing processes, but its primary action relates to its antibacterial effects. While the benefits of hydration, closure of pores, and reduction of puffiness may occur as secondary effects of the treatment, the fundamental mechanism behind the effectiveness of Tesla high-frequency currents is their ability to combat bacteria on the skin's surface.
