Child age 12years any treatment for heal skin torn.

superfast healing. Fortunately children heal very quickly due to their excellent health and circulation. Any torn skin should be immediately replaced back over the open area and held in place using either adhesive strips or stitches. Leaving wounds open to the air is bad bad bad and slows down healing. Keep this area covered and protected and it will heal rapidly.
Pls clarify. If you are asking what to put on a laceration/cur of the skin, clean it well keep it dry and place a thin layer of neosporin or other antibacterial. If it is a dirty cut, be sure your child has a tetanus shot up to date.
