Taz and azelaic acid

[newuser:]

I’m on 0.05 tretinoin, should I switch to 0.045% taz and 10% azelaic acid? They say taz is more faster in getting results. I might be overthinking, I just got 10% azelaic acid on Amazon (idk if will be the same as a prescription one), but I need your guys opinion

(I bought this one, I just realized I probably got scammed, i don’t know if it’s the azelaic acid everyone’s talking about)
