An embodiment of a system includes a power source and at least two electrode assembles which may be arranged in a pair( Van, I am trying to compensate here for the mention of the pair below but I don't quite know what you wanted so say in light of what appears to be a typo in the following sentence). The power source has an output current that alternates between a maximum and a minimum current value. Each electrode assembly is configured to be held in contact with a skin layer of a user. Additionally, each electrode assembly includes an electrode that is coupled to the power source to receive the output current from the power source. At least one of the electrode assemblies in the pair includes a medium that carries an active agent having a charge, the medium being provided on the at least one electrode assembly to enable the output current to repel the active agent into the skin layer for a duration in which the output current has a polarity that is the same as a polarity of the active agent. |
