The present invention features a device having a barrier membrane
contacting surface, the device containing: a power source; a first
conductive electrode; a second conductive electrode; a first light
emitting diode; and a carrier containing an active agent; wherein the
power source is in electric communication with the first conductive
electrode, the second conductive electrode, and the light emitting diode,
and wherein the device is arranged such that light from the first light
emitting diode and the carrier are in communication with the barrier
membrane contacting surface.
