Which treatment for congestion involves the use of an electrode held by an esthetician and applied to the client's face?

The treatment for congestion that involves the use of an electrode held by an esthetician and applied to the client's face is direct high frequency. This method utilizes a high-frequency electrical current to stimulate the skin, enhancing circulation, and promoting healing. It is particularly effective for treating acne and congestion as it has antibacterial properties that help reduce inflammation and kill acne-causing bacteria.

Direct high frequency can also assist in the overall rejuvenation of the skin by increasing cell turnover and improving the effectiveness of topical products. The electrode is applied directly to the skin, allowing for targeted treatment where needed. This method is popular among estheticians for its visible results and its ability to help clients achieve clearer, healthier skin.
