What is one of the effects of high-frequency current?

  1. Magnetic

  2. Electrolytic

  3. Thermal

  4. Infrared

The correct answer is: Thermal

High-frequency current is known for producing a thermal effect, which is one of its primary effects. When high-frequency electrical currents pass through the body, they generate heat due to the rapid oscillation of the electrical energy. This heat can increase blood circulation, promote tissue metabolism, and aid in the healing process. The thermal effect can be beneficial in various cosmetic and therapeutic applications, such as skin rejuvenation or pain relief. It is important to understand that this heating effect is generally targeted and carefully controlled in a professional setting to avoid potential tissue damage or discomfort to the client. While other effects like magnetic or electrolytic can occur with different types of currents, and infrared light can relate to heating effects, they are not the main focus of high-frequency currents in the context of barbering or beauty treatments.
