10000% recommend!! Great product. I got my sample last week, and this stuff really seems to be amazing! The sample was very generous (way more than I expected) and they sent it out for free, and all they've asked for in return is honest feedback and reviews. I have been struggling with cold sores my entire life (since I was like 7 or maybe even younger) and I did feel like I mostly had outbreaks under control (with Lysine, avoiding triggers, and using tea tree oil when I had a sore), but I recently started HRT and the hormones have triggered multiple outbreaks in the last few weeks. I was skeptical when I got the sample, but decided to give it a go, and when I had a sore start up last week, I used only the LipCur (even though I wanted to take Acyclovir and use tea tree) so I could see how well this stuff would really work. My sore stayed small and was gone completely in two days. It never got itchy and tingly or anything. Yesterday I went on a field trip with my kiddo and tossed the LipCur in my backpack just in case and thank goodness I did. As I was sitting on a bench waiting for the kids to be rounded up to leave, I noticed my upper lip was tingly and a little raised. I put the LipCur on immediately, and several times during the evening, and this morning it was completely gone! No spot, no scab, nothing. Don't sleep on this, even if you're skeptical! I'm ordering an extra one tonight even though I just opened my sample.
