my skin has been all over the place this month

Genuinely didn't expect the change in weather to hit my skin this hard. It's not even that cold yet but something shifted and suddenly my face is dry in places it's never dry, and a bit oily in others. Doesn't make sense. Honestly I don't know much about skincare — I've got like three products and I rotate them depending on what feels wrong. But what's actually helped more than anything is just drinking more water and not skipping sleep. Boring answer I know. I started layering moisturiser before bed instead of just doing it in the morning and that's made a difference tbh. Also stopped washing my face with really hot water which was apparently the issue all along. Room temp or slightly warm and it's been less reactive since. Small thing but still.
