Which condition is commonly treated with high-frequency currents?

1. Dry skin

2. Acne

3. Hyperpigmentation

4. Wrinkles

The correct answer is: Acne

High-frequency currents are widely recognized for their effectiveness in treating acne. This treatment works by generating a mild electrical current that is passed through an electrode applied to the skin, resulting in the production of ozone. The ozone has antimicrobial properties, which can help kill the bacteria responsible for acne. Additionally, high-frequency currents can promote healing by increasing blood circulation and stimulating cellular regeneration, which is crucial for reducing acne lesions and preventing future breakouts. While other skin concerns such as dry skin, hyperpigmentation, and wrinkles can also benefit from different modalities, they are not the primary focus when using high-frequency currents. For instance, dry skin typically requires moisturizing treatments, and hyperpigmentation is often addressed with lightening agents or laser therapies. Conversely, the anti-inflammatory and antibacterial effects of high-frequency make it specifically advantageous for acne treatment, positioning it as the most suitable answer in this context.
