Okay so its day two of the Zovirax and the blisters have already began to go into remission and scab over. In the past large obs on this level generally spread to the skin around my lips but this contained them to the lip itself, plus many of these obs would have taken close to a month to heal. I'm very impressed with the cream, it makes them feel much better and not look as noticeable. I bet in three days they will be completely gone. Thanks Zovirax!
