for Cold Sores
Topical zinc oxide cream applied to cold sores with some evidence for reducing severity and healing time.
How it works
Zinc has antiviral properties through inhibition of HSV thymidine kinase and direct virucidal effects at the cell membrane.
What to watch for
Apply every 2 hours for best results. Results are inconsistent — works better for some people than others. Not a substitute for antivirals in frequent recurrences.
