Which type of burn completely destroys skin and muscle tissue?

A third degree burn is characterized by the complete destruction of both the skin and underlying muscle tissue. This type of burn typically extends through the epidermis and dermis and may penetrate into the subcutaneous layers beneath the skin. The damage is so severe that the affected area often appears charred or white, and it may feel numb due to nerve damage. This is contrasted with first degree burns, which affect only the outer layer of skin and result in redness and minor pain, and second degree burns, which involve the outer layer and part of the underlying layer, leading to blisters and swelling. Minor burns typically refer to less severe burns that can heal with at-home care and do not cause significant tissue damage. Thus, the critical aspect distinguishing a third degree burn is its ability to completely destroy skin and muscle tissue, leading to the most severe level of burn injuries among the options presented.
