[Product Request] My face is chronically dry, flaking, red and painful

Hi all, so I've (25M, if it matters) been fighting with the skin on my face and scalp nearly all my life. Namely, around my nose, pretty much anywhere hair grows on my head, around my earlobes. But lately, it's gotten really bad, to the point where it's constantly painful and super embarrassing.

Particularly the areas around my nose and between my eyes/eyebrows, I can moisturize, get rid of all the skin flakes, wash my face, etc. and it's flaking again within 10 minutes. It's always there and I can see it in my peripheral when I'm talking to people, and I'm getting self conscious. On top of that, my skin feels like it's burning all the time, which isn't helping the fact I need to wash my face in the bathroom a couple times an hour (when possible).

I work a blue collar trade where I'm exposed to shielding gases - namely a welder - but I've been doing this for years and it's never gotten this bad. I wash my face in the shower with a generic psoriasis soap and sometimes Dove face soap, and I usually shower twice a day. I moisturize my face using the Cerave psoriasis cream and my doctor has prescribed me a Ketoconazole 2% face cream, which was helping a lot for a while, but now it's getting worse again. I've also tried putting sunscreen on which helps sometimes but again the flaking is persisting through.

Is there anything I can do? My face is splotchy and as red as a tomato, it's embarrassing to even look at people. I feel like I look unclean. Is there any product I could try that really helps? Thank you!
