Sorry I wasn't more specific in the title, but I have 3 questions about potentially starting the regimen

First, how long does the 8oz bundle last? I live in Canada so I'm thinking of buying the larger sizes to save on the $20 shipping

Also, how do I work the AHA into the regimen? I do have old acne marks and PIH that won't seem to go away, but i've heard you should wait before incorporating AHA

Last, can I use it one only one side/portion of my face? I rarely get acne on the left side (it's actually quite clear) of my face but the right side and the area between my bottom lip and chin look like a warzone. Should I still use the moisturizer on my left side but no other product?
