First off for full disclosure, I have never been diagnosed with rosacea. First, my wife mentioned I always had a sunburn on my cheeks and nose. Then I realized my nose acne was getting worse and worse and there didn't seem to be any reason. I started doing research online and found a probable cause, rosacea. Reading possible conditions I met exactly. So, I figured what the heck, I'd try some prosacea for the price. After a week or so of consistent use, my acne on my nose was almost completely gone. Another week and the redness is so reduced it's almost gone. It's just slightly blotchy now. When I discontinue use, it does eventually come back after weeks to a couple of months. When I start using it again, it goes away after a week or two. I'm convinced it's no coincidence, it works well for me. As with anything, I'm sure it won't work for everyone, but for the price it's well worth a try.
