High-frequency current is primarily used to treat which condition?

High-frequency current is particularly effective in treating conditions that involve inflammation and microbial activity, such as acne. This form of electrical current helps to disinfect the skin and reduce inflammation, making it ideal for acne treatment. High-frequency techniques work by producing ozone, which has antiseptic properties that can kill bacteria that contribute to acne outbreaks. The heat generated during the treatment also promotes circulation and can aid in the healing process of the skin.

While hirsutism, psoriasis, and allergic reactions may benefit from other types of treatments, they are not primarily treated with high-frequency currents. Hirsutism typically involves hormonal therapies or electrolysis rather than high-frequency treatments. Psoriasis is usually managed with topical steroids or phototherapy, and allergic reactions are handled with antihistamines or steroids, rather than high-frequency application. Thus, the context surrounding the use of high-frequency current clearly aligns with treating acne as the primary condition.
