|Dab on cream|
If you dab on an antiviral / cold sore cream as soon as you feel your skin tingling you may prevent the sore from appearing.
|Use sun block|
Always wear sun block, especially over the areas where you get cold sores. Use a lip blam with a sun protection factor of at least 15.
Apply ice to the sore four or five times a day.
|Wash and dry the sore|
Keep the sore clean and dry by washing it with soap and water, then patting it dry.
|Use vitamin B|
Add a vitamin B supplement to your diet as it is good at preventing sores around the edges and in the corner of the mouth.
Camphor will dry your sore and help it go away. However, be careful as it is possible to dry the blister out so much that it may crack and bleed.
Apply a water-based zinc solution to the sore as soon as you feel the tingle. Zinc may inhibit the virus from duplicating. Apply the solution every 30 to 60 minutes during the onset of the sore.
