What type of wound involves a break in both the dermis and epidermis of the skin?

A wound that involves a break in both the dermis and epidermis is classified as a full-thickness wound. This type of wound extends through the epidermis, past the dermis, and into the subcutaneous tissue or beyond. The injury affects the entire thickness of the skin, and healing typically involves the formation of granulation tissue and may result in scarring.

In contrast, a partial-thickness wound only breaches the epidermis and part of the dermis, which means not all layers of the skin are compromised. A superficial wound, on the other hand, involves only the epidermis and does not penetrate beyond it. A closed wound is one where the skin remains intact despite underlying tissue being damaged, thereby not involving any break in the skin. Understanding these classifications is essential for proper wound care and healing management.
