You have to buy this!

Yes! So this really works. I was a bit skeptical about it at first but bought after three cold sores on 1 lip anyway. Of course, it is a bit more expensive than an ointment but really worth a lot of money. As soon as I feel a cold sore coming up or think I feel coming up, I put the burner on it and it really won't come through! Had nothing for at least a year now. And that with being sick/having been pregnant and low resistance.
