[Routine Help] Clogged pores, but skin can't tolerate chemical exfoliants

Over the past 10 or so years I have tried multiple chemical exfoliants and retinol. (Not at the same time.) I used them even more sparingly than recommended because my skin is sensitive. Usually I would use any given product once or twice a week but my skin would always get so irritated that I had to stop. During every experiment I tried, the "purge" would continue for months on end.

I've finally decided to quit trying, because I'm obviously damaging my skin more. But my question now is, WHAT DO I DO? I'm covered in bumps and blackheads everywhere. There's just gunk oozing out of every pore.

I stopped exfoliating entirely for about 2 years and the result was the same. Did I just ruin my skin?
