In skin treatment, how does iontophoresis primarily function?

Iontophoresis primarily functions by using electric currents to enhance product absorption within the skin. This technique involves passing a low-level electrical current through the skin, which facilitates the penetration of topical solutions or ingredients that are applied during the treatment. The electrical current helps to push these products deeper into the skin layers, making them more effective and increasing their bioavailability.

This method is particularly beneficial for delivering active ingredients such as vitamins, peptides, and other skin-rejuvenating substances directly to the target areas. By promoting deeper absorption, iontophoresis can improve the overall efficacy of skin treatments, allowing for more significant and visible results than what might be achieved through traditional application methods alone.

Understanding this process also highlights the importance of electrical currents in various skin treatments, emphasizing the role of technology in enhancing skincare outcomes.
