20 Natural Remedies for a Cold Sore
Petroleum Jelly
Petroleum jelly won't make your cold sore disappear any faster, but it can help make the process of dealing with one a little less miserable. In addition to hydrating the cracked skin that surrounds a cold sore, petroleum jelly can also help create a barrier between your blister and any irritants in the outside world.
To use petroleum jelly, simply apply a little directly to the surface of your cold sore. You won't need a ton to experience its effects, but it can be useful to reapply throughout the day.
