Metronidazole
"I had seriousl Rosecea that I allowed to go undiagnosed/untreated for years.  Until the point it effected my eyes and then I knew I had to do something. I have been using this cream for 5 days now in addition to a sulfa wash, doxycycline daily and CreaVe moisturizer. The results are slow (but my case was extreme so keep that in mind) but I'm starting to notice improvements in the texture of my skin as well as decreased redness and swelling. I use it 2 times daily. My advice is be patient with it. Don't expect overnight results but I think you will be pleased after strict continued use within a week or so."
