Skin feels hot and burning

After becoming pregnant and reaching the middle stage

Suddenly, my skin became extremely dry.

Dead skin also seems to peel off like dandruff.

Moreover, I haven't worn a mask for a while.

I wore a mask because I was going to the hospital, and around my mouth and chin...

It feels so burningㅜ

Is my face dry, so the mask isn't good?

I can't tell if it's due to pregnancy.
