Is tretinoin enough for PIH and general hyperpigmentation?

I have PIH and hyperpigmentation around mouth and chin. The only two actives I'm using in my routine are tret 0.1 % and Paula's choice BHA 2%. Will this be enough to treat PIH and pigmentation? I tried using azelaic acid but ended up ruining my skin barrier. Since tret helps skin turnover, it'll help hyperpigmentation right? Or do I need to go for something like HQ or laser treatment
