What type of skin damage occurs in a 2nd degree burn?

In the case of a 2nd degree burn, the damage involves both the outer layer of skin, known as the epidermis, and the inner layer, called the dermis. This type of burn typically results in blisters, swelling, and severe pain due to the involvement of the dermis, where the nerve endings are more abundant.

The formation of blisters occurs as the body’s response to damage to both layers, allowing fluid to accumulate between the epidermis and dermis. This is a protective mechanism that helps to protect the underlying layers while they heal.

In contrast, if only the outer layer were affected, which characterizes 1st degree burns, there would be no blisters, and healing would occur without significant damage to deeper tissues. Since 2nd degree burns also do not extend to the muscle or deep tissue beneath the dermis, as might occur with a 3rd degree burn, it is correct to identify that both the outer and inner layers of skin sustain damage in a 2nd degree burn. This understanding is crucial for proper first aid and treatment practices.
