Don't forcibly remove the scab. This will just spontaneously fall off. I suggest that you continue applying the moisturizer. At this point, we just want to avoid infections or further wounds in the area as this may lead to scarring. Do not pick or frequently manipulate the area. Use a mild toothpaste preferably one which contains less fluoride. Avoid spicy food and hot beverages. Cold sores should resolve spontaneously although there is a good chance this may recur.
