rosacea
"My derm gave me some samples to try because I can't afford laser treatments.  Applied some on day one.  A little sting but that was gone quickly.  Within minutes I noticed a definite reduction in the redness.  Within an hour my face was just slightly pink.  Spent the day enjoying not having to look at the deep red on my face in the mirror.  Day two was a different story.  The rebound was so bad the redness was back even worse than before and the pain was excruciating.  Even had some puffiness like my skin was rebelling.  I chucked all the samples in the trash.  I'll never Mirvaso again.  Hope others have better luck."
