You can still use the current lotion/scrub with the Epidermx. You can wash your face with Cetaphil before Epidermx (I don't use any cleanser before the Epidermx as it thoroughly cleans my skin already). But you don't need to use the Neutrogena scrub on the days you use the Epidermx. After a few weeks, I think you don't need to use the Neutrogena scrub any more.
I've heard of a few small breakouts with camellia oil. But many others have no problems, including some from this board that said they had oily skin. So just like anything else, everyone's reaction to a skin care product is different. You don't need to use it if you are concerned, or test it on a small patch of your skin before going full face.
