Kerri67 -
I have used Renova, but didn't really see a lot of difference with it, so for now, I've dropped it from my regimen. I've never heard of or used green cream. For now, I'm really pleased with the products I'm using & am getting great results - although I do adjust things from time to time. I know some ladies do incorporate Retin-A (or similar products) into their CP/glycolic routines without any problems.
