Worth getting 15-20% azelaic acid if I’m already on tretinoin?

I’ve been using 0.05% tretinoin for a while now and my skin is tolerating it pretty well.

I’m mainly trying to get rid of post-acne marks (PIE/PIH) and improve overall skin texture. I was thinking about adding azelaic acid.

Would you guys just buy a 10% azelaic acid from a drugstore, or is it worth getting a 15-20% one from a pharmacy/prescription if I can?

If you're already handling 0.05% tret decently adding 15-20% azelaic is worth it 10% drugstore shit is weak cope for real PIH/PIE.
