1 The skin is a barrier to the outside world protecting the body from infection, radiation, and extremes of temperature.  There are many types of wounds that can damage the skin including abrasions, lacerations, rupture injuries, punctures, and penetrating wounds.
A superficial laceration is thoroughly washed with sterile solution, and the bleeding is stopped. The edges of the wound may be held together with Steri-Strips, butterfly bandages, tissue glue, or sutures to hasten healing. Then the wound is covered with antibiotic ointment and bandaged. A tetanus booster may be given if 7 to 10 years have passed since the individual's last tetanus immunization.
