I can see dead skin cells on my skin in the mirror today.

I looked in the mirror today and my skin looked dry and dull for some reason.
My makeup felt like it was flaking, so I took a closer look and saw that dead skin cells had surfaced.

I'm pretty sure it was fine until yesterday
Suddenly, my skin texture became rough and even felt tight...
My skin condition seems to be fluctuating lately, perhaps because of the changing seasons.

I heard that if you forcefully push them away in times like this, they become even more sensitive.
I'm currently focusing on soothing and moisturizing care.
How do you all manage dead skin cells when they start to flak?
