Retin-A (Non-acne) Use ... Add Moisturizer or Not?

I recently changed to a line of organic face products (and boy are there a lot! Step 1 to 6) w/various serums & creams. Most likely overkill (and the manufacturer's way of getting me to buy more) I decided to commit. However I still notice blotchy spots/large pores. When I used Retin A in the past, I peeled & my skin felt like it was burning. The last time I included moisturizer but I didn't feel it worked as well. Is it better w/o? And should I replace my Vit A serum w/Retin A in the line up?
