Quick question - I have both Active C and Renova and will be beginning those products within the next few weeks. What are the differences? You don't use both at the same time, right? With the Renova, I had to use it only a few times a week...does the Active C give you the flaking and peeling also? Anyone like one over the other?

FYI - I bought Active C b/c I remember seeing it in Dr B's book under my skin type and ULTA was not going to be carrying La Roch Posey anymore so it was on clearence...I think I got it for 1/2 the normal price.
