Oxymetazoline
"Wow! It makes all the redness and little broken capillaries literally disappear! I only have mild rosácea with some flushing. I've been using it for a couple of months. I'm so impressed!!!! My skin looks better than it has in years, and I can go light on my foundation or skip it!  I do feel a tingly sensation at times on my face, but it's worth the trade off for me. I'm very happy with Rhofade!"
