Renova is wonderful stuff. I am using it as a preventative measure for wrinkles. After seeing the outrageous escalating prices of over the counter wrinkle prevention creams at the counters, I decided to go with a real prescription cream, since they are about the same price. Plus Renova has been clinically proven to help with wrinkles and I'd trust a doctor before I'd trust a sales person. Anyway, it did dry my skin out a lot for the first week or two. And it was very sensitive durring that time. All of my fragranced moisturizers stung real bad for about 4 minutes after applying. I no longer have that problem though. My skin, which has always been very nice, is just softer and smoother than ever.
