Ice Application
for Cold Sores
Applying a wrapped ice pack or cold wet cloth to the cold sore for 5–10 minutes several times daily during the blister stage.
How it works
Cold reduces local inflammation, numbs pain receptors and may slow viral replication by lowering tissue temperature at the infection site.
What to watch for
Wrap ice in a cloth — direct ice contact can damage skin. Provides symptomatic relief only, does not speed healing.
