rosacea
"Not good.  The first few days were fine though not overly impressive, after that more redness and itching.  It also doesn't appear to compatible with any of the moisturizers I have tried.  I've stopped using it and my face is less red and much better.  $20 in the garbage, I would not recommend this to anyone.  And judging by all the others with issues I'm surprised it's still on the market."
