I would look into PHA-based exfoliants, they are the most gentle. Maybe one of those products? https://whatsinmyjar.com/search/exfoliators-and-peels/pha-exfoliators?category_body_part=Face&without_ingredient=Glycolic%20acid&without_ingredient=Salicylic%20acid&sortBy=Irritancy
Important question. Most of us have been pushed to use the wrong acids/exfoliants for our skin types. Have you tried MANDELIC acid, or LACTIC acid? Mild acids are great. It’s better to take 8 to 12 months to resolve an uneven complexion, over injuring or drying out our skin. It’s not supposed to be harsh. I think that both Asian and European skincare practitioners understand this better than many where I am, meaning USA. Best of luck!
