What is necrosis tissue?

Necrosis refers to the death of cells or tissues in the body, resulting from a lack of blood supply, which is essential for delivering oxygen and nutrients. When tissue is deprived of oxygen, as seen in various conditions such as ischemia or infections, the cells can no longer sustain their metabolic processes, leading to cell death. This dead tissue is characterized by a lack of cellular integrity and function, often resulting in inflammation and the body’s attempt to clear away the dead cells. Understanding necrosis is vital for estheticians because it can be associated with skin conditions that require specific treatment approaches, such as wound care or the management of conditions leading to tissue damage.

The other options do not accurately describe necrosis. Healthy tissue is functioning optimally, while inflamed tissue indicates a response to injury or infection rather than death. Scar tissue, on the other hand, is a result of the healing process following injury, where the body replaces lost tissue, but does not equate to the necrosis itself.
