I confess that I didnât know the geological conventions for abbreviating time until I started teaching the geology writing class and looked them up. (Thatâs despite having published a paper on argon-argon geochronology.
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.
The main benefits and effects of Galvanic Iontophoresis include: 1  Tightening and firming of tissues. 2  Constriction of follicles. 3  Decrease in blood flow. 4  Decrease in sensitivity. 5  Reduction of edema and lymph stagnation.
