Any type of injury to the skin can produce inflammation which in turn produces post-inflammatory hyper-pigmentation. An incision, acne pimple, insect bite, or a rash from poison oak can produce post-inflammatory hyper-pigmentation. The darker a patients natural pigmentation, the more intense (darker) and more persistent is a spot created by post inflammatory hyper-pigmentation. In lightly pigmented skin post-inflammatory hyper-pigmentation usually disappears in less than six months, but in darkly pigmented skin may last for 2 to 4 years or more.
