Good home care for dry, flaky skin during the changing seasons

A lot of dead skin cells are flaking off on my face, appearing white.

My face feels very tight, and it feels like an extra layer has been built up.

Is my face feeling tight because I have a lot of dead skin cells?

I wonder if dead skin cells are coming off because my face is in bad condition.

I'm not entirely sure, but in any case, his face doesn't look well.

I've tried exfoliating foam cleansers, but

It only worked for a short time, and it seems like it has been about a month since the condition started like this.

Please recommend some home care methods that I can use more actively.
