The most common cause of burn injury is hot oil. These burns tend to happen most commonly in young children and the elderly 

First degree and superficial second degree burns are ‘partial thickness’ burns, which will heal with dressing changes only, as there is still healthy cells deep to the burn to regenerate the upper layers of skin.

Deep second degree and third degree burns (full thickness) most often require surgery to remove the nonviable skin and replace it with skin grafts.
