The main benefit of using a high-frequency machine in skincare is its ability to stimulate blood circulation and kill bacteria. High-frequency machines utilize electrical currents that create oscillations in the skin, enhancing blood flow and oxygenation. This improved circulation promotes better nutrient delivery to the skin, which supports overall skin health and vitality.

Additionally, the electrical currents have antibacterial properties, making high-frequency treatments particularly effective for acne-prone skin. By destroying acne-causing bacteria and helping to reduce inflammation, the high-frequency method can significantly improve the condition of the skin.

While the other benefits listed, such as moisture retention, reducing the appearance of fine lines, and improving skin tone, may also occur as secondary effects of enhanced circulation and general skin health, the primary and most immediate benefit is the combination of stimulated blood circulation and antibacterial action.
