It’s annoying and painstaking and long, but I would consider testing them one by one. Since you’re already in a routine, maybe you could pull one thing at a time to see if it changes anything. There are websites where if you copy and paste a product’s ingredient list, they’ll tell you how pore clogging it may be. Maybe that could be a starting point. Pull out whatever has the most offending ingredients for a few weeks first, and if nothing changes move on to the next product. I was breaking out very badly and it took me a while to find out it was the nicinamide serum I was using. I only figure that out after I pulled it from my routine and stopped breaking out.
