Zilactin cold sore gel, medicated gel - 0.25 Oz (AXBAB4680-53876)
Cold Sore/Fever Blister Treatment, Oral Pain Reliever.
This product is amazing! I suffer from cold sores about every 3 months and I've tried everything on the market. I applied on my lip as soon as I started feeling the tingling and swelling start. It stopped it from festering into a large sore and was gone in about 2 days. No one at work even noticed I had the fever blister!
