rosacea
"Awful experience.  First 2 days were perfect and then the rebound flushing began. I never have flushed that bad before. It was dark red/purple, painful and swollen. I should have stopped then but I kept thinking my skin would adjust. Didn't want to give up on it but finally quit using after 3 weeks. Took a week for the rebound flushing to quit after discontinuing use. I went back to my baseline redness everywhere but my forehead. It is redder than when I began treatment."
