Wound Care refers to the various medical therapies designed to accelerate or improve the process of wound healing. Wound healing itself is an intricate process where the skin (or another organ-tissue) repairs itself after injury. In normal skin, the epidermis (outermost layer) and dermis (inner or deeper layer) exist in a steady-state equilibrium, forming a protective barrier against the external environment. Once the protective barrier is broken, the normal (physiologic) process of wound healing is immediately set in motion. Upon injury to the skin, a set of complex biochemical events takes place in a closely orchestrated cascade to repair the damage. The classic model of wound healing is divided into three sequential, yet overlapping, phases: (1) inflammation, (2) proliferation and (3) remodeling.
