I must agree with this. I use an off brand of this athletes foot spray that has the same medicine it it and BHT. It also is the spray that has some talc. If I feel a tingle I apply this and just leave it on for a while at home. It will wipe right off when I want it to. It has stopped all cold sores from developing for 5 months. If I feel a scare I just put it on. Dont wait until you get one, prevention is the best way to deal with these.
I used this product called "Tinactin" (its an athletes foot spray) I used it for 3 days morning and night .I sprayed it on and let it dry,(I used it because Tinactin has an anti itch medicine in it )after the 3rd day the blisters were gone and i have not had an out break for about 1 year.
