Paula’s choice blunder!!

I always had soft clean skin. Recently started noticing dullness so researched a lot and bought Paula’s choice aha bha 2% toner. It did not work at all, additionally it broke my skin really bad. Since then I am very careful for what I pit on my face but NOTHING is working. Any tips?? I also have black facial hair with thick side burns, got laser done last year but I am back to square one. I need to shave every week and I am frustrated. Main goal is to heal the skin and get rid of dullness.
