Skin that felt balanced all summer can suddenly feel tight the moment the air turns dry. The fix is rarely a whole new routine — usually it is one swap: a richer night cream, or a heavier moisturiser layered over the same serum you already trust.
Watch for the first sign rather than waiting for full-on dryness: a little pull after cleansing is the cue to add a step back in, not to change everything at once.
You do not need a new routine for every season — usually just one thoughtful swap.
