What is Post-Inflammatory Hyperpigmentation?
Brown or red marks remaining after acne or wound-related inflammation heals
Excess melanin production leaves spots darker than the surrounding skin tone, which can darken further with UV exposure.
Main causes & characteristics of Post-Inflammatory Hyperpigmentation
When acne or wounds cause inflammation, melanocytes are known to become stimulated and overproduce melanin. This pigment remains in the epidermis and dermis, appearing as dark brown or reddish marks darker than the surrounding skin. UV exposure is known to further activate melanin production, which may cause the marks to deepen.
Managing Post-Inflammatory Hyperpigmentation
Sun protection is fundamentally recommended above all else, and applying sunscreen generously before going outdoors is advisable. Products containing tone-evening ingredients such as vitamin C and niacinamide may help. If the marks are widespread or persist for a long time, consulting a dermatologist is recommended.
