Questions regarding who is recommended for exfoliation care

Perhaps because of the changing seasons, my makeup keeps flaking and my skin feels dry and rough, so I am looking into recommendations for exfoliation care.

I am concerned about the white bumps that appear around my nose and chin, even though I wash my face thoroughly.

I am curious about the specific skin types for which exfoliation care is recommended.

Can dry or sensitive skin be included in the exfoliation care recommendations, not just oily skin?

I am worried that it might actually be irritating, so I would like to know if there is a suitable exfoliation method recommended for those with a weakened skin barrier like mine.

I would appreciate it if you could explain in detail the characteristics of those recommended by experts for urgent exfoliation care.
