Post-Inflammatory Pigmentation

Post-inflammatory hyperpigmentation (also known as PIH and hyperpigmentation caused by inflammation) is a type of hyperpigmentation that can affect the face and body. It appears as flat spots of discolouration. These range in color from pink to red, brown or black, depending on skin tone and the depth of discoloration. Men and women are equally susceptible, and all skin types can get post-inflammatory hyperpigmentation although it is more prevalent in darker tones of skin.

Treatments

A variety of topical treatments have been used to treat epidermal postinflammatory hyperpigmentation, with varying degrees of success. These agents include hydroquinone, tretinoin cream, corticosteroids, glycolic acid (GA), and azelaic acid.
