Herpes Simplex
"I haven&#039;t had a full on cold sore in 10 years. All due to Abreva. As soon as I feel that warm feeling and see a little red on my lip I apply it and an hour later it&#039;s gone. I keep a tube at home and in my car.  I&#039;ll even apply some before a big date or event just in case. This stuff is amazing.  I deal with clients daily, a cold sore is a deal breaker. Miracle."
