It probably was aveeno cold sore ointment with propolis. I've heard good things about it from folks I know who get cold sores and use it. You need to apply it every 2-3 hours while awake from the very first sign of a developing cold sore for it to be most effective.
Have you talked to your doctor about oral antivirals for cold sores too to help speed healing?

No, I haven't. I usually take L-Lysine when I feel it coming on, but I hear that is more effective if you take it daily. I really haven't found anything that "speeds" healing. It always tends to last about a week no matter what I do. I haven't gotten one in awhile. It seems as though I always get them this time of year though...maybe because my lips tend to get chapped this time of year?? who knows. Thanks for the Aveeno tip...we'll see how that works.
