This and lysine ointment are my go to cold sore remedies. I dab the lysine ointment on first, then this. I love that it creates a barrier over the cold sore, it makes it much less noticeable, and also makes me stress less about them spreading. I've tried all the cold sore remedies out there, this is by far one of the best.
This is now an item I must have at all times. I tried it on a friends recommendation, and my cold sore was gone in a matter of days, as opposed to the usual 2 weeks. It also seemed to have helped with the severity. It didn't get as big as they usually do. It's also a nice lip balm for when you don't have any cold sores.
