I am 27 and I get cold sores (sounds like i'm at an aa meeting). Really, I've been looking for remedies and trying them out all my life. I found one that I'm gonna throw out there cuz I haven't heard many people talk about it.
Go to youtube and watch the video I made of my last outbreak. Search for VyGone... It'll take a minute of your time and probably change the way you think about cold sores.
I used to stress about getting cold sores and I'm told that just makes them worse. Now that I found this vygone thing, getting a cold sore doesn't stop me cuz I know as soon as I feel it I can stop it.
Good luck and check out the video
