Post-inflammatory hyperpigmentation (flat, darkened patches)

Post-inflammatory hyperpigmentation is a type of hyperpigmentation that can occur on the face and body. This condition usually develops as a response to inflammation (such as acne) or injury (such as a chemical peel or laser therapy).

Post-inflammatory hyperpigmentation can occur in all skin types, but it is more common in darker skinned people. Men and women are equally susceptible to this skin condition.

With post-inflammatory hyperpigmentation flat, darkened patches appear. These patches can range in colour from pink to red, brown or black, depending on the complexion and the depth of discolouration. They may resemble small, faded freckles or larger patches of darker skin. They may be shiny or resemble ‘new’ skin.


Your treating doctor will discuss the treatment options with you. You can also contact your doctor if you have any other questions about this skin condition.
