In this video, user littlesecretsmakeup teaches you how to get rid of cold sores fast. The first time you notice a cold sore, you should apply something to it to speed up the healing process. One option is Campho Phenique cream. Use hydro peroxide on it, during the night, applying with a Q-tip. You can also apply gel deodorant. This will help get rid of it between 2 and 3 days. The process should be repeated each day, once a day and night. To avoid increasing the damage, don't use chapstick as this only moves all the germs around.
