How do you manage your skin condition during the seasonal change?

The weather has been changing so drastically lately that it's put a red flag on my skin care routine. Even though I'm using my usual cosmetics, my skin is still extremely dry and flaky. I'd like to systematically review my lifestyle and basic skincare routine to improve my skin condition. Could you give me some advice?
