I have had rosacea for 10 years. I have tried finacea, metrogel, clarifoam, oracea, egg white masks and a few other creams I don't recall...over the years.
The only thing that has worked very well is a prescription (PPT Sulf 3% Petrolatum) that I had filled at a compounding pharmacy called Bigelow Chemists in NYC. I really didn't even think it would work since the clarifoam (which is also sulphur based) didn't work. I put a little on my face every night before bed and it seems to be working quite well and is not drying due to the petrolatum base.
I have also decided to supplement this with the Boiron "sulphur" homeopathic beads (for skin rash worsened by heat and water) in the small blue tube from Whole Foods. I'm not sure if these beads do anything, but something is working on the sulphur front!!
I hope this helps someone!
