My rosacea had improved a lot in about 2 weeks using the black onitment. It's been about a month now and I don't use it every night. Every now and then I have a tiny bump appear and I use it again, just in case the roseacea is trying to come back. I'm not taking any chances!! The only thing left as a result of years of rosacea is tiny spider veins on my cheeks. They don't look bad thank goodness.
