Retinal

I never had any pimple on my face, but from previous year i started getting some due to over exposed serums actives on my face. That's a blunder fr. I started incorporating retinal from may..its been two months , I noticed smoothness, but have alot of dark marks from initial subtle purging. It's now week9 my marks are feeling kindoff diffused at the edges. It's been hard for me cz my family is been judging for my current appearance. They don't know that I am using retinal and this is common.

How to deal with it and how many months will it take to fade the marks completely??
