The best way to prevent a skin injury is to take extraordinary care when you are performing tasks that leave you at risk for such an injury. If you work in an environment that makes skin injury likely, wear protective clothing. For instance, avoid handling industrial chemicals without gloves. If you do housework, be sure to avoid loose fitting clothing while cooking on the stove to prevent a burn.
In order to prevent another skin injury, frostbite, you should avoid being outside for long periods of time when it is cold, wet, or windy, and if you must be outside during this weather, you should wear several layers of warm clothing. Covering your ears and hands with hats and gloves can also help you prevent the injury.
To prevent infection from a skin injury, take prescribed antibiotics and be sure to visit the doctor.
