Mechanisms of Iontophoretic Transport
(1) Paracellular transport
Molecules are transported through the lipid bilayer region
(2) Appendageal transport
Molecules traverse the stratum corneum through appendages.
(3) Transcellular transport
Ions are transported directly through corneocytes
comprising the stratum corneum.
The role of each mechanism is still largely in question.
