herpes simplex
"I bought this after I had my first breakout in years, it wasn't that bad but I had an event coming up and wanted it to be gone asap. So I go to the pharmacy buy this really expensive product, apply it just like the package said to and it got worse and took longer to completely heal. The cream was painful and just prolonged everything.  I stupidly decided to give it another chance and the next time was even worse. After that I started having breakouts all the time,  sometimes twice a month. I wrote the company and complained but no one bothered to write back. Since then I've been using high doses of vitamin c and it's awesome. I take 6000mg vitamin c right when I feel one coming on and it prevents it 99% of the time."
