well, if he did rip some skin off of them, my opinion is wash it with soap, then use iodine, then wrap it in that medical cotton stuff and secure it with medical tape, and when a scab starts forming, apply aloe (it speeds healing and takes away pain), my aloe of choice is "Soirx blue norther aloe gel plus lidocaine" Im not sure where you get it, but I swear the stuff is magical and would probably cure skin cancer. Im not a doctor, dont listen to me.(<-----my disclaimer)
