Worked better than I thought

Cold sores don't happen often for me and always use Abreva with no luck in healing. I saw Clera and thought I would give it it a try. Was very impressed. Started using Clera after cold sore had appeared on my lip and it immediately helped with the itching and burning. I kept the cold sore covered with the Clera all day (probably using too much). The next morning there was quite a difference. The cold sore was almost gone! I continued to use it and the cold sore was literally healed in about 2 days! Highly impressed with Clera!
