Post-inflammatory Hyperpigmentation

The most common type of “scar” for acne patients isn’t a true scar at all, but rather a condition called
post-inflammatory hyperpigmentation (PIH). Nearly everyone with acne develops some degree of post-inflammatory hyperpigmentation.

PIH looks like a flat area of discoloration on the skin and, as the name suggests, develops after an inflammatory lesion heals. PIH is the skin’s natural response to a wound. Luckily, PIH is not permanent, and will fade away over time. Certain treatments, such as Retin A, azelaic acid, microdermabrasion, and
chemical peels may help fade discolorations more quickly. More ยป
