Small bumps appear on my cheeks during the change of seasons. What is the best way to manage this?

With the change of seasons these days, I am concerned about the bumpy, granular areas on the skin around my cheeks.

It isn't large, red acne breakouts, but if I look closely at the surface of my skin, there are fine bumps, and it doesn't feel as smooth to the touch as it used to. At first, I thought it was just dead skin cells building up, but I'm worried that if I keep exfoliating blindly, my skin might become even more sensitive.

Could these small bumps also be considered milia or comedones? I am curious if milia can form as sebum accumulates inside the pores, even if my skin tends to be dry. I would also like to know the difference between simply having rough skin texture and actually having skin problems.

If I receive a skin care consultation, can I determine whether extraction is necessary or if it is more appropriate to proceed with other treatments first?

Rather than managing it aggressively from the start, I want to identify the cause of the recurring minor breakouts while minimizing stress on my cheek skin. I would also like to know about skincare habits I should pay attention to at home.
