I received a package of Orajel Single Dose Cold Sore Treatment + Moisturizer to test out. Can it be this stuff really works in one shot? I felt the all-too-familiar of a cold sore outbreak on the rise and ran to get my sample of Orajel Single Dose. Crack the tube, dab it on, massage in, slight tingle. I returned to the tube later to see if I could eek out all the healing liquid goodness inside, but it was all dried up. No matter, because a day later, there was nothing there! Normally I’d have a big welt by then. So, at least this time, it worked! I’m so used to having to apply and reapply ointment that I still find it hard to believe that one application was all it took.
