the one product switch that actually sorted my autumn skin

Right so every year I tell myself I'm going to be proactive about swapping my routine before the central heating kicks in. Every year I am not. But this time I genuinely did it early and the difference is noticeable enough that I had to say something. Basically what I did — and I'm not a dermatologist but six years of obsessing over this stuff counts for something — is just swap my lightweight gel moisturiser for something with a bit more ceramide content. That's it. Nothing dramatic. The gel was doing fine all summer but the moment the air got drier it just... stopped being enough. Skin felt tight by midday, that kind of uncomfortable tight where you're very aware of your face. Added a ceramide-heavy cream on top of my usual hyaluronic acid layer and within a few days the tightness was mostly gone. The barrier stuff I've been reading about for years actually clicked into place when I felt the difference in real time, which was oddly satisfying. Still keeping the collagen in the AM routine because that's not seasonal for me, that's just life at this point.
