can the dermotologist cure this?

hi ,

im a young guy who had spots and during that period i washed and scratched my
face on the cheeks so badly that i got really rough dead skin and a slight
colour difference where i treated my skin rough. The colour is different
because it is dead skin and it gets red sometimes, but other part of my face
at the side and forehead look totally normal and fresh.

Anyway there are no scars or anything but its just really dead and dry and
starts to flake off , my nose has become redish too because i scratched a lot
there.

I cant beleive how mad i was to do that to my skin, anyway im going to the
dermatologist soon and want to know if theres any chance if they can make my
skin normal again.

thanks
