anyone’s skin flare from stress this fast?

Three weeks into this seb derm thing (eyebrows and around my nose, so a bit different from the usual eczema posts here) and it had actually started calming down. Then I had two interviews back to back this week and by the second one the flaking was bad enough I could see it under the office lights. Still using the same gentle cleanser, still moisturizing twice a day like the derm told me, nothing new added. Anyone else’s skin react to stress that fast, or should I be looking at the routine instead?
