The primary benefit of direct high frequency for oily skin lies in its germicidal and drying effect. Direct high frequency uses an electrical current to produce a mild thermal and chemical reaction in the skin, which helps to eliminate bacteria on the surface. This property makes it particularly effective for individuals with oily skin, as it can help to reduce acne and other blemishes associated with excess oil and bacteria.

Moreover, the drying effect can assist in regulating oil production, leading to a clearer complexion. The utilization of high frequency treatments can also help tighten the skin and minimize pores, providing further benefits for those struggling with oily skin conditions.

In contrast, hydration, exfoliation, and moisturization are not the primary benefits of this treatment. While hydration and moisturization are essential for maintaining skin health, the direct high frequency treatment specifically targets issues associated with oiliness rather than aiming to replenish moisture.
