 How does it compare to the Pep-40 Serum?  I'm on A/S for that together with the Pep-40 Cream.

So this is an am/pm serum with retinol. If I use a different retinol (at night) would I want to use this?  If I use a Vit C (or any other acid) in the AM can I still use this on top? Is there anything i should not use with this?  I guess I am just trying to figure out if I would use this with everything I use now or INSTEAD of what I currently use...
