Retinol induced hypersensitivity - how long will this last?

I was on Obagi Brightenex 0.5 for a month and half while also getting in a low percentage glycolic peel in between...I stopped the product because my face was constantly red and I initially only wanted a chemical peel in the first place....1-2 months later (now) , I get rashes when my body heats up (exercise) and my face is hypersensitive...I'm using sensitive skin products + SPF so will this just take time to heal? I still get redness and flake a little here and there...any tips/warnings?
