Which of the following is NOT an effect of high-frequency current?

1. Antiseptic

2. Thermal

3. Analgesic

4. Stimulation

The correct answer is: Analgesic

High-frequency current, commonly used in various beauty and barbering treatments, has several notable effects on the skin and tissues. Among the choices, the analgesic effect is the one that high-frequency current does not primarily provide. Antiseptic properties are a significant effect of high-frequency current. This type of current helps in disinfecting the skin, promoting healing by killing bacteria, which makes it particularly useful in treating acne and other skin conditions. The thermal effect is also a characteristic feature. High-frequency currents generate heat due to their oscillation, which can aid in increasing blood circulation and relax tissues, enhancing the overall health of the skin. Stimulation is another effect of high-frequency currents. The current stimulates cellular activity, boosting metabolism and promoting better absorption of nutrients, which can be beneficial for skin rejuvenation. However, an analgesic effect, which would involve providing pain relief, is not a primary function of high-frequency currents. While it might have mild effects in that direction for some individuals, it is not a recognized or significant benefit in the same way as the other effects mentioned. This deficiency in pain relief is what sets it apart from the other choices listed.
