Should I Keep A Cold Sore Wet Or Dry?
Most people do best with a balanced approach: keep a cold sore lightly moist while it is open or weeping to reduce cracking and contamination, then let it dry naturally as a scab forms. Constant wetting or aggressive drying can both cause problems. The right choice depends on the sore’s stage, your comfort, and whether you are using antiviral treatment. For frequent, severe, or unusual sores, consult a pharmacist or doctor.
