Rosacea
"DO NOT USE THIS PRODUCT!  My 15 year old son is light-skinned, blonde and blue eyed and tends to flush(German descent).  This bothered him, so we spoke to his dermatologist and she prescribed Mirvaso.  He was so excited to try it and applied it thinly over his face.  Within 20 minutes his skin was deathly pale with mottling at the edges and around his eyes.  He looked terrible.  Within 10 hours, his face started turning an angry red as if he had been slapped repeatedly.  He then started feeling faint.  I took him to the med clinic and the doctor there prescribed steroids to reduce inflammation and Benadryl.  We are still waiting anxiously for his handsome face to return to normal.  This is after ONE use."
