Iontophoresis is a physical process in which ions flow diffusively in a medium driven by an applied electric field.ontophoresis of acetylcholine is used in research as a way to test the health of the endothelium by stimulating endothelium-dependent generation of nitric oxide and subsequent microvascular vasodilation.
In a nutshell, iontophoresis is the more effective delivery of ingredients (such as vitamins, antioxidants or peptides) that permeate the skin beyond the superficial level. The term is partially derived from the Greek word phoresis for movement and the electrical term ion, to define the use of electrical movements.
