Burn injuries

Burn injuries can be classified as first-degree, second-degree, third-degree, and fourth-degree according to their depth [6,122-126]. Based on a thorough understanding of this classification, a group of researchers mathematically developed a skin burn

model that can measure the time required to generate different degrees of burns on the human body [126-132].

First-degree burns

First-degree burns mainly affect the epidermis. This type of burn is also called a superficial burn. With these burns, vasodilatation of subcapillary vessels occurs. This causes redness and pain to the region affected. Generally, no blister occurs in such burns, and discomfort is temporary [124]. Hence, healing is normally very rapid with no permanent scars or discoloration.

Second-degree burns

Second-degree burns mainly occur on the epidermis and dermis layers. Such burns can also be classified as superficial and deep. In superficial burns of this category, only the epidermis layer is affected. This generates moist blisters, and causes pain to the skin. In this case, healing is normally prompt with no scars because the majority of the cells at the dermal base are unaffected. On the other hand, deep second-degree burns affect the dermis layer too; in turn, the capillaries or blood vessels are also affected. This situation causes tissue edema and blisters on the skin [6,122,124].
