Today's weather fine dust

There is a lot of fine dust today and it's so dry.

On days with heavy fine dust, my skin feels like it suddenly gets dry, and I wonder why. Ugh.

Even though I am using the product as is, some days it is fine, while on other days it becomes particularly dry and rough.

Especially on days with high levels of fine dust, my skin feels stiffer even after washing my face, and the tightness seems to get worse by evening.

I spray mist and use a humidifier, but it's just not working.

Do you have any other tips?
