[Routine Help] hi folks! I’m not very informed about this stuff but need some help fixing my super flaky skin!

Hi everybody. I’m 27F and my skin is just kinda bleh. I’m always flaky NO MATTER WHAT I do. Makeup won’t sit right on my face, black shirts are kinda out, and I’m just really unhappy with how I look. I use tretinoin but I’ve been using the same strength for over a year so it’s not my skin just adjusting. Here’s my routine:

Morning: sometimes moisturizer, sometimes not. SPF 50+ if I’m venturing outside for even a moment. Occasionally I’ll use skinceuticals vitamin c e ferulic but I’m pretty sure it makes me break out and it smells like death.

Night: wash with cerave hydrating cleanser, Vichy mineral 89, curology formula (Tretinoin 0.018%, Clindamycin phosphate 1%, Azelaic acid 8%), cerave moisturizing cream, and lately, aquaphor on my chin, nose, and forehead which is where I’m flakiest. I used to use skinceuticals triple lipid cream but that didn’t seem to be doing anything to moisturize my skin.

Help!
