What is post-infammatory hyperpigmentation?

-It is a discolouration that is left on the skin after an underlying skin disease has healed.

-The underlying skin disease may be trauma, skin infection, eczema (dermatitis) or a drug reaction.

-In dark-skinned persons, the colour tends to be more intense and persists for a longer period.

-The pigmentation tends to fade slowly with time.



Post-inflammatory Hyperpigmentation (following dermatitis)



How is post-inflammatory hyperpigmentation treated ?

-Usually, normal skin colour will return slowly over a period of months.

-One should avoid further trauma to the area, e.g. frequent rubbing and sunlight exposure.

-In hyperpigmentation, bleaching agents such as those containing hydroquinone may be used. The latter is however not more rapidly effective than if no treatment is given. Creams containing derivatives of vitamin A are not recommended as they induce an inflammation which worsens the problem.
