I don't get alot of acne, but I have alot of skin discoloration and redness around my lips and jaw because of hyperpigmentation.
I've been using Tretinoin for two months and as of yet haven't notice an improvement.
Is there any recomendations on what I can and should do to treat hyperpigmentation and redness.
My skin around the corners of my mouth and chin/jaw region drys out and gets flaky rather easy with using cleasners while my forehead is rather oily.
I know nothing is overnight, but how long does it usually take to see a noticeable difference upon using any type of moisturizer/cleanser?
and is it likely to get worse before it gets better?

Finally is it bad to use on type for a couple of days and then switch to another and then switch back to the original?

I had a chemical peel this past week.
A superficial Navita one, would that do more harm than good since I'm using Tretinoin and how many would I have to have to notice an improvement?, I assume it's unlikely to notice an improvement after one, seeing as I only had the stuff on for 7 minutes.

Does stress and eating habits effect skin discoloration and hyperpigmentation and does complete body cleanses help clear up your skin?

Sorry for all the questions.
