Acne Scar Treatments in Bangkok Guide

Postinflammatory hyperpigmentation can occur in anyone but is more common in darker-skinned individuals, in whom the colour tends to be more intense and persist for a longer period than in lighter skin colours. Pigmentation tends to more pronounced in sun-induced skin conditions such as phytophotodermatitis and lichenoid dermatoses (skin conditions with lichen planus-like inflammation, such as erythema dyschromicum perstans).

Some medications may also darken postinflammatory pigmentation. These include antimalarial drugs, clofazimine, tetracycline, anticancer drugs such as bleomycin (flagellate erythema), doxorubicin, 5-fluorouracil and busulfan.

Postinflammatory hyperpigmentation follows damage to the epidermis and/or dermis with deposition of melanin within the keratinocytes (skin cells) and/or dermis.

Inflammation in the epidermis stimulates melanocytes to increase melanin synthesis and to transfer the pigment to surrounding keratinocytes (epidermal melanosis). If the basal layer is injured (e.g. lichen planus), melanin pigment is released and subsequently trapped by macrophages in the papillary dermis (dermal melanosis or pigment incontinence).

How is postinflammatory hyperpigmentation diagnosed?

Postinflammatory hyperpigmentation is diagnosed by taking a careful history and examining the skin. Dermal melanosis gives a characteristic hue to the skin colour (grey-purple-brown).

Sometimes the diagnosis is only made after skin biopsy. Histopathology reveals patchy epidermal melanosis and/or dermal melanosis.
