I purchased a 2.2 oz tube on Amazon for $16 and change.
I am pleasantly surprised at how effective this stuff actually is. I did a 3 week test using my Rx Finacea on one side of my face and this on the other (I have mild/blushing rosacea on both cheeks) and this performed just as well as the Finacea. This moisturizes too which my Finacea does not do. Also, the broken capillaries on along the side of my nose appear a bit less red - bonus!
My actual rating is 4.5 lippies because it (like the Finacea) does not get rid of my redness totally (at this point, I'm thinking nothing will), but this does a very nice job.
