I have questions about exfoliation care.

Whether it is because I am getting older or because of the changing seasons, it seems I need to take care of my dead skin cells.
I didn't really take special care of it; I just made sure to lather it well and apply moisturizing cream.
Lately, I've noticed my dead skin cells becoming hard and my skin feeling cracked, so I think I might need some exfoliation.
What exfoliation treatments would you recommend? I am also curious about the satisfaction levels.
I'm also curious about things like the frequency or cost.
This varies from person to person and depends on the clinic or type of procedure, but I think a standard exfoliation routine would suffice.
I am curious if there are any tips for exfoliating without any procedures.
What I do is such a simple and common method that I’m actually curious about the know-how of the experts.
