My non-medical opinion is that the skin never heals and it can be a month later and still be dead. I get rid of the dead skin when possible. It's a pretty sure bet that it's good skin underneath.
mmm yeah - im kinda at the point that I think the medical benefits for keeping the skin (ie to protect and heal) has passed and now I am probably at more risk of creating blisters for having loose dead skin. Hence might be now best to remove it.
Glad your thinking is the same - others are the same?
Make like Nike and 'just do it' already. :P
