What causes and staph infection to turn your skin black?

A staph infection can lead to skin necrosis or tissue death, which may cause the affected area to turn black. This discoloration often results from the destruction of blood vessels and the subsequent loss of blood supply to the skin, leading to tissue breakdown. In severe cases, the bacteria can produce toxins that contribute to the rapid deterioration of skin and underlying tissues. Prompt medical treatment is crucial to manage the infection and prevent further complications.
