The effects of high frequency current include antiseptic and what other effect?

Cooling
Thermal
Hydrating
Drying

The correct answer is: Thermal

Most people hear the word "frequency" and think of something vibrating at a fast pace. However, the effects of high frequency current are not related to vibration. Instead, they are related to thermal or heat energy. High frequency currents create heat in the skin, which can improve circulation and stimulate cell renewal. This heat also has an antiseptic effect, helping to kill bacteria and prevent future breakouts. A Cooling is incorrect because high frequency current creates heat, not coolness. C: Hydrating is incorrect because while the heat may increase circulation and make the skin appear more plump and moisturized, it is not directly hydrating the skin. D: Drying is incorrect because high frequency currents actually aid in drying out excess oil production in the skin, making them beneficial for those with oily or acne-prone skin. Overall, high frequency current's effects are more related to thermal energy than anything else.
