My doc gave me cortisone but idk is it really good to clear redness and heal the dead cells(I used alcohol on my skin and it became red) also have a lil hole but will cortisone really help for that specific matter?
Cortisone only does two things: it reduces inflammation and pain. It has no effect on healing except where inflammation is preventing it. So, for your condition, it will reduce the redness, and that's all.
