If you suffer from cold sores, you've probably experiences the weeks of tingles to blisters to scaring healing. I've had cold sore since I was a child and every time the tingles started, I dreaded the next few weeks. Last June I had a cold sore that I treated with a prescription medication for the first time and it stopped it from blistering, great! Then earlier this week the tingle started again but I was unable to get the medication until the next day. I remembered that I had purchased this cream a month or so prior as a just in case and I'm so happy I did. You guys, the cold sore is gone! I used this for approx 48 hours. This is unbelievable. Years of cold sores! This is a special product and I hope it can reach all who suffer from the agony cold sores bring. Thank you Green Goo!
