Checking my skin condition these days - dry and hot skin ㅠㅠ

I'm trying to check my skin condition these days...

The acne and skin troubles that I used to get frequently have subsided, but I don't know if it's because the heater was turned on too much due to the cold weather, but my face is dry and feels particularly hot ㅠㅠ

Because of that, the red marks stand out more.

I'm curious as to what you do to reduce fever.
