What is the primary effect of using Direct High Frequency on the skin?

1. Promotes skin cooling

2. Reduces oiliness and kills bacteria

3. Increases blood flow

4. Stimulates collagen production

The correct answer is: Reduces oiliness and kills bacteria

The primary effect of using Direct High Frequency on the skin is the reduction of oiliness and the ability to kill bacteria. This treatment utilizes an electrical current to produce a thermal effect, which is particularly beneficial for individuals with oily and acne-prone skin. The heat generated by the current helps to dry out excess sebum, effectively reducing oiliness. Additionally, the high frequency creates an oxygen atomization effect, which is lethal to bacteria and can therefore help in preventing and treating acne breakouts. Direct High Frequency is a key step in many facial treatments aimed at promoting clearer skin as it not only addresses current bacterial issues but also creates an environment that is less conducive to new bacteria developing. This dual action is particularly valuable in esthetics, as it enhances overall skin health while providing immediate benefits.
