To aid in reducing my PIH, I was prescribed tretinoin 0.025% and Azelaic acid 15% topical cream. Is it worth it to take the risk with tretinoin, or should I just stick with Azelaic acid? I would like something to smooth the dull texture of my skin and erase hyperpigmentation. My skin is slightly sensitive and when my acne does occur, I experience small comedones and textural irregularities.
