Plus, the cold weather condition seems to worsen the outbreaks. I've tried a lot of different types of cold sore treatments, from oral pills to home remedies. But nothing works great, except Prosurx.

It doesn't leave any redness or burning when applied. Besides, it eases uncomfortable of cold sore recurrences and rapidly heals blisters on my lips. Finally, I find the best cure option for my cold sores."
