If it's just flaky and dry it's not a problem. Tortoises are reptiles and shed their skin just like snakes... except snakes do it all in one go. Tortoises shed gradually and can spend a lot of time looking tatty. Don't pick or pull at it, just let it rub off naturally.
If there's signs of sore skin, then it should be treated with a small amount of antiseptic ointment.

If it were an open sore, I'd apply antiseptic, but not if it's healing nicely. Judge it like a human graze.
