To get rid of a cold sore on your lip you can apply some ice to the cold sore which will help reduce the swelling of the cold sore helping it to disappear.
Then apply some Apple Cider Vinegar to the cold sore using a Q Tip or cotton ball and leave the Apple Cider Vinegar on the cold sore overnight.
You can also apply the Apple Cider Vinegar to the cold sore 2 to 3 times per day to help the cold sore go away much sooner.
The apple cider vinegar is antibacterial and antiviral so it will kill off the virus causing the cold sore.
Toothpaste is another option to get rid of a cold sore and you just apply the toothpaste to the cold sore and leave it on the cold sore until it dries out.
The toothpaste will dry out the cold sore making it fall off eventually.
