I'm currently looking at these azelaic acid products (accessible to me) for treating my post-inflammatory erythema (PIE). For those who've tried any of these products before, can share your experiences regarding its efficacy and how well it layers between other products (since AA is such a finicky ingredient). Would really appreciate your inputs!
