Small blemishes pop up on days when my nose and cheeks feel stuffy. I'm curious about how to manage this.

On days when my face feels stuffy for a long time, I feel like small bumps form more easily on the sides of my nose and inside my cheeks.

At first, I thought my skin texture had just gotten rough, but after a few days, a few would pop up like small blemishes.

It isn't severe red or painful acne, but once it appears, it makes my skin look uneven, so it bothers me constantly.

In such cases, could it be caused by sebum or dead skin cells clogging the pores?

I am also wondering whether it is better to get extractions right away or to soothe the skin and manage sebum first. Besides applying light skincare products to keep the skin from feeling stuffy, I would like to know if there are any preventative measures, and what treatment method would be suitable.
