Microcurrent therapy in esthetics primarily plays a role in improving muscle tone. This therapy involves the application of low-level electrical currents to the skin, which helps stimulate facial muscles, encouraging contraction and relaxation similarly to a workout for facial muscles. This process can enhance the definition of facial contours, lift sagging skin, and promote a more youthful appearance.

The effectiveness of microcurrent therapy lies in its ability to stimulate the production of adenosine triphosphate (ATP), which boosts cellular energy and promotes tissue repair and regeneration. This stimulation can lead to improved muscle strength and tone, resulting in a firmer and more lifted appearance of the skin.

Other options, while important in esthetics, do not align with the specific functions of microcurrent therapy. For instance, hydration is typically addressed through topical products or treatments that deliver moisture to the skin, chemical exfoliation involves techniques like peels to remove dead skin cells, and excess sebum removal usually relies on cleansing or specialized treatments. Thus, the focus of microcurrent therapy distinctly aligns with enhancing muscle tone, making it the correct choice in this context.
