What is another name for Tesla current?

1. Low frequency current

2. Medium frequency current

3. High frequency current

4. Direct current

The correct answer is: High frequency current

Tesla current, also known as high frequency current, is a type of electrical current that vibrates at a high frequency and is often used in various beauty and skin care treatments. This form of current produces a high-frequency oscillation that can enhance circulation, promote cellular repair, and improve the overall texture and tone of the skin. High frequency current stands out in esthetics for its ability to provide therapeutic benefits, particularly in treating issues such as acne and aging skin. It can help to disinfect the skin, reduce inflammation, and stimulate collagen production, making it a valuable tool in an esthetician's toolkit. Other terms, like low frequency or medium frequency current, refer to different types of electrical currents that operate at lower oscillation rates and are associated with distinct use cases that may not align with the applications of Tesla current. Direct current is a unidirectional flow of electric charge, which differs significantly from the alternating current characteristics of Tesla current used in therapeutic and cosmetic treatments.
