What effects are produced by microcurrent treatments?

Microcurrent treatments are designed to stimulate the underlying muscles and tissues, which can lead to muscle toning and contouring of the face. These treatments use low-level electrical currents that mimic the body's natural electrical signals, promoting collagen and elastin production while improving circulation. This stimulation helps enhance the skin's overall appearance by providing a lifting effect.

While some of the other options touch on beneficial effects, such as improving skin texture or hydration, they do not capture the primary action of microcurrent treatments, which focuses specifically on muscle stimulation and toning. Therefore, option B accurately reflects the core benefits associated with microcurrent technology in esthetics. Additionally, microcurrent treatments are often utilized for their rejuvenating and firming effects, which directly ties into the muscle stimulation aspect.
