I am a DSPW and need to use a lightening gel both morning and night, according to regimen in the book.  Can I use a lightening gel and Renova?  I suppose I would put the gel on first and then the Renova?  As I mentioned in another post, I have the Clarisonic so maybe I should use the Renova every other night and the Clarisonic on the off nights?  I don't want to cause a mess!!!

Also, Dr B list Skineffects Advanced Brightening Complex as a lightner and I just checked CVS's website and it says to apply it to the whole face. I thought I should just put it on the spots?? Also it contains retinol...will my using Renova hurt anything?
