rosacea
"I'm 69 years old, have had episodes of Rosacea occasionally for   19 years. Metronidizole cream had only moderate effect. My doctor gave me a sample of Soolantra, and my skin cleared up in just a few days. I continue to have no symptoms after using up the sample tube, which I used very sparingly to make it last. The price is so high and my Part D plan doesn't cover it, so that's the down side."
