What is the primary purpose of micro-current therapy?

1. To increase electrical resistance

2. To induce skin peeling

3. To retrain facial muscles

4. To create a relaxing massage effect

The correct answer is: To retrain facial muscles

Micro-current therapy primarily focuses on retraining facial muscles by using low-level electrical currents that mimic the natural electrical signals produced by the body. This therapy is particularly effective in stimulating the muscles, enhancing their tone and firmness, which can lead to a more youthful appearance. The mild electrical stimulation promotes collagen and elastin production, aiding in overall skin health while targeting specific muscle groups in the face to restore and maintain muscle strength and coordination. While options related to increasing electrical resistance or inducing skin peeling address different processes, they do not capture the essence of micro-current therapy’s action. Additionally, although micro-current therapy can have a soothing effect like a massage, its primary function is not to create relaxation, but rather to actively engage and strengthen the facial muscles. Thus, the correct focus on retraining facial muscles distinguishes micro-current therapy within the aesthetic realm.
