[routine help] Where to include AHA 8% gel? Also shea butter.

Beauty Tips For Body Care
Hey there skin care addictsI'm [24F, Australia] about to start including paula's choice AHA 8% gel in my skin care routine and have a question - where is the best place to put it? I've read the side bar and searched the sub, but I have a vit C serum and tret in the AM/PM respectively and I'm not sure where to best put it. I'm also thinking about including shea butter, somewhere but I'm not sure where that would go, or it if would be too much?Current routine:AMCleanse - clinique liquid facial soap (mild)Serumtologie vit C serum (2 months in - no dramas here)Simple rich moisturising lotion50/50 mix of Neutrogena ultra sheer face spf50+ and Bali Body BB cream (reapply later)PMCleanse - (as above)Tretinoin 0.025% - every second night (sometimes I apply Simple moisturiser 30 minutes later, sometimes I can't stay awake. 1 month in, no dramas here either)Non-tret nights - Palmers Cocoa Butter skin therapy oil (face) then Simple moisturiserCan I use the AHA in the morning as long as I apply ~30 minutes before the vit C serum (which iirc has a pH of about 6.5)? Or would I be better off using it at night on non-tret days, and if yes - can I still include the palmers oil (i'm loving it)? Or something else? I'm a grad student (work at home) so waiting for things to absorb in the AM is not a big deal, but I hate waiting at night because I procrastinate cleansing my face.Thanks :-)
