To shorten the duration and size of cold sores, use ASA. Put a tablet on a spoon, then a drop of water to make a paste. Put it on the sore (you will feel it tingle). The ASA will dry up. Just keep putting it on. It will reduce redness and shorten the out break quickly. I use this when at home and instead of going out with a big white mass on my lip, I just brush it off and the sores are almost invisible. I have fewer outbreaks since I stopped drinking soda. I thank others on this site for that gem, as I used to get outbreaks every spring and late fall, signaling a weather change usually within a month.
EC: ASA is the acronym for acetylsalicylic acid, or ASPIRIN.
