[Routine Help] Recommenations to combat PIH/hyperpigmentation? Current routine inside

Beauty Tips For Body Care
Hi guys!I'd love any recommendations for changes or additions to my routine. Let me lay out the details. (Also, just to put this out there, I have read the information about PIH linked in the sidebar.)I don't have much too much hyperpigmentation, but I have several dark acne marks, and they're ruining my self esteem, so I'm trying to get rid of them. I know these things take time, but I'd love to speed up the process! I'm prone to marks, and I've had marks last for over 2 years before.Here's a photo album of the PIH that I'm concerned about (sorry for the iPhone level of quality): http://imgur.com/a/TkMfJHere is my current routine:AM:Wash face with Cetaphil Daily CleanserApply MUAC fade serum on marks (enhanced ingredients are Alpha Arbutin, Kojic Acid, Licorice Extract, Mulberry Leaf Extract, Resveratol, Lactic Acid, and Niacinamide [Vitamin B3]. PH level is 4.5)Apply Cetaphil Moisturizing Lotion once MUAC fade serum has driedApply Neutrogena Ultra-Sheer Dry-Touch Broad Spectrum SPF 30 sunscreen (thinking about switching to a higher SPF)Apply makeup once sunscreen has absorbed (none of my makeup is acne causing)PM:Wash face with Cetaphil Daily CleanserApply MUAC fade serum on marksApply Alpha Hydrox AHA Enhanced Lotion (10% glycolic acid) once fade serum has driedApply Cetaphil Moisturizing Lotion once AHA has driedApply Ziana (0.025 tretinoin) once moisturizer has dried ** Other:**Twice a week: MUAC 40% lactic acid peel (I started with once a week but upped it to twice a week after three peels; so far I've done five)Up next: Once I've completed 8 weeks of bi-weekly lactic peels or run out of the peel (whichever comes first), I plan on trying MUAC's fade peelI'm new to the Alpha Hydrox AHA. It doesn't burn my skin at all. The lactic peel doesn't really irritate me at all either, especially not on the areas with PIH. The Ziana/tretinoin sometimes dried out my skin a bit, but now that I'm exfoliating with AHA, that doesn't seem to happen anymore.Any pointers would be greatly appreciated! :)
