This lemon balm lip LomaProtect salve for cold sores works in the same way as LomaHerpan cream, but also contains a sunblock. Sunlight triggers cold sores so adding sunblock makes the salve extra useful for dealing with facial cold sores. (This salve was previously called LomaBrit salve.) You can use it daily as a way to prevent cold sore, or just when you feel a cold sore coming up.
Melissa, the active ingredient in these products, contains a molecule that blocks the receptor site on the skin cell, so the virus cannot get in.
4.75 gram salve stick.
