Post-inflammatory hyperpigmentation can be seen as the body’s response to an injury or inflammation of the skin with an overproduction or uneven distribution of melanin. The trauma or irritation induced by acne, cuts, eczema or sunburn is met with a flush of pigment (melanin) that supports the deeper layers of the skin from further damage and boosts the wound-healing process.
That said, while the irregular disposition of the pigment may seem similar to that of a scar, inflammatory hyperpigmentation is vastly different from it. A distinct characteristic of PIH is that it typically does not alter the texture of the skin but shows up as flat, discolored patches that are deeper than your natural skin tone. Moreover, unlike scars, the severity and duration of these dark patches are based on a variety of factors, depending on individuals, genetics, depth of inflammation, as well as skin tone.
Understanding the distinction between the two is integral to pinpointing the post-inflammatory hyperpigmentation treatment that is best suited for your needs to mitigate any potential impacts and ensure healthy, even-toned skin.
