A sudden flushing party... What could be the cause? ㅠㅠ

Since I returned to work recently, my skin is getting drier and rougher day by day. Working all day in a dry environment while breathing in dust, my whole face feels tight by the time I get off work, and redness flares up especially on my cheeks. My skin didn't used to react this sensitively, and it upsets me that my skin barrier seems to have thinned and weakened significantly now that I've entered my mid-30s. When I look in the mirror, my pores seem to have stretched vertically, and I can feel my overall complexion turning sallow, so I think I need to get some emergency treatment tonight.

First off, as soon as I got off work, I gently washed my face with a mild, slightly acidic cleanser. I set aside my usual functional ampoules for a while and switched to a routine focused solely on hydration, soothing, and barrier restoration. I soaked a cotton pad with a toner generously infused with ceramide and centella extract and placed it on my cheeks like a mask for about 10 minutes, and I can feel the heat sensation subsiding a bit.

I scooped out about double the usual amount of thick panthenol cream, applied it thickly all over my face like a sleeping mask, and am writing this while lying down haha. I really hope this redness subsides by tomorrow morning and my skin returns to being firm and supple. How do you all treat your skin firsthand when it flares up suddenly when you're tired or stressed? Please share any tips you have likes ㅠㅠ I'm going to get a good night's sleep hoping my skin condition recovers at least a little bit tomorrow.
