What does the term 'electrotherapy' refer to in skin treatment?

The term 'electrotherapy' in skin treatment specifically refers to the application of electrical currents for therapeutic effects. This technique is employed in various aesthetic and medical practices to enhance skin health and appearance. Through the use of electrical currents, electrotherapy can stimulate muscle contractions, improve blood circulation, promote lymphatic drainage, enhance product penetration, and even help in collagen production, leading to rejuvenation of the skin.

While other treatments mentioned, such as chemical peels, manual massage techniques, and application of topical products, are also valuable in skincare, they do not fall under the definition of electrotherapy. These methods rely on physical, chemical, or topical means rather than the application of electrical currents, which is the distinctive characteristic of electrotherapy.
