What is one common purpose of using a high-frequency facial machine?

Using a high-frequency facial machine is particularly effective for treating acne, which explains why the correct answer highlights its ability to kill bacteria and reduce inflammation. The high-frequency current emitted by the machine has antiseptic properties, making it beneficial for targeting acne-causing bacteria on the skin. Additionally, this treatment helps to reduce inflammation by increasing blood circulation and oxygenating the skin, facilitating a healthier environment for healing.

The other choices illustrate important functions of various skincare treatments, but they do not specifically pertain to the primary benefits of high-frequency machines in the context of acne. While hydrating the skin and improving texture is an important aspect of many facial treatments, it is not a primary function of high-frequency machines. Similarly, enhancing the absorption of skincare products is more closely associated with techniques such as iontophoresis or ultrasonic therapy. Finally, while stimulating collagen production is an important goal in many anti-aging treatments, it is not the main focus of high-frequency therapy, which is more geared towards acne management.
