My skin has suddenly become dry and dull. What could be the reason?

Lately, my skin definitely feels drier than before. I haven't changed my basic skincare products much, and I wash my face as usual, but it bothers me because my makeup feels cakey when I apply it. My cheeks, in particular, look a bit rough, and my pores seem more prominent. I'm not sure if it's due to the season or an issue with my skin condition. I'm wondering if it can improve with home care, and I'd also like to know how anyone who has had a similar experience managed their skin.
