Glad you asked...
There are a couple of different techniques that can be used by someone trying to heal raw skin. One thing that you can do is put vasaline on the affected area.

Raw skin needs protection from friction in order to heal. A barrier can be created between the skin, and any possible irritants by the use of oils, and ointments. Make sure to keep the skin from friction as much as possible.
