The Inhibitor is designed to be applied to the skin once every 30 minutes when the initial tingle of a cold sore begins or when treating an existing lesion. It works by sending a light current of electricity between the two probes that are located on the top of the device. These probes are able to deliver a 10-volt charge that releases less than 10 milliamps of electricity. Timed signals on the front of the device light up to alert the user when the charge has been applied. Treatment with The Inhibitor is as easy as centering the affected area of the skin between the two probes and pressing the button. Applying the charge in a criss-cross pattern by turning the device 90 degrees and adding a second charge has proven to be the most effective healing method for the majority of users. Each individual treatment takes only seconds to perform. The charge is painless and leaves no marks on the skin.
