Definition

  • Burns to the skin
  • A burn is a heat, chemical or electrical injury to the skin

Causes of Burns

  • Hot Liquids (such as coffee) are the most common cause of burns. They cause a scald.
  • Hot Surfaces. Examples are ovens, stoves, space heaters and curling irons.
  • Chemical Burns (Serious). Examples are acids or lye splashed on the skin. They continue to damage the skin until they are removed.
  • Electrical Burns (Serious). They can be much deeper than they first appear.
  • Flame Burns (Serious). Flammable liquid burns are mainly seen in teen boys.
  • Friction Burns. Treadmill burns are a common example.
  • Sunburn is not covered here. See the Sunburn care guide.
     

Degrees of Burns

  • 1st degree. Red skin without blisters. These burns don't need to be seen.
  • 2nd degree. Red skin with blisters. Heals from the bottom up, not from the edges. Takes 2 to 3 weeks. Small closed blisters decrease pain and act as a natural bandage.
  • 3rd degree. Deep burns with white or charred skin. There are no blisters. Skin feeling is lost. Heals in from the edges. Grafts are often needed if it is larger than a quarter in size. These are burns over 1 inch or 2.5 cm. Skin grafts help limit scarring.
