herpes simplex
"I've gotten cold sores for a few years now, usually one small one every few months maybe. As soon as I feel the tingle I put this on and it shortens the healing time to just a few days (2-3) and keeps it looking skin toned rather than that gross red or white. Also I load up on L-Lysine which has really helped reduce the frequency of outbreaks. It's now been almost 6 months since my last visible cold sore."
