rosacea
"Over the course of about 3 years I have been prescribed over a dozen different creams and gels, all of which were ultimately ineffective. A couple actually burned my skin. 
For me Soolantra has been a revelation. Within a few days I was seeing positive results and after no longer than 3 weeks it had pretty much cleared up. I then stopped using it, and now occasionally rub a little cream in if I get paranoid(but I probably don't need to)"
