"second-degree burn"的定义和意义

What is a "second-degree burn"?

A second-degree burn affects both the outer layer of the skin and the underlying layer. It causes redness, pain, swelling, and blistering, with the skin often appearing wet or shiny. These burns are more serious than first-degree burns and can be very painful. Healing time varies but generally takes several weeks, and there may be some scarring. Treatment includes cooling the burn with cold water, covering it with a clean, non-stick bandage, and seeking medical attention to prevent infection and promote healing.
