    Postinflammatory hypopigmentation is a frequently encountered concern, especially in patients with

    skin of color because of the contrasting color. It often represents sequelae of both primary

    cutaneous conditions as well as secondary to therapeutic interventions, signifying the importance of

    providing informed consent when performing any intervention that could potentially cause

    postinflammatory hypopigmentation. Skin lightening is thought to be due to a decrease in the

    amount of melanin and, interestingly, there tends to be a variable response depending on the

    degree of the inflammation, as well as on the patients individual tendency, which may be

    genetically predetermined based on the lability of an individuals melanocytes.[71]

    Postinflammatory hypopigmentation is frequently seen as a sequela of seborrheic dermatitis, tinea

    versicolor, atopic dermatitis, psoriasis, lichen planus, lichen striatus, thermal injury, pityriasis

    lichenoides and mycosis fungoides, to name a few.

    Hipopigmentasi pasca inflamasi merupakan masalah yang sering dihadapi , terutama pada pasien

    dengan kulit berwarna karena warna yang kontras . Ini seringkali merupakan gejala sisa dari kedua

    melakukan informed consentsaat melakukan intervensi apapun yang berpotensi menyebabkan

    hipopigmentasi pasca inflamasi. Pencerah kulit dianggap penyebab dari penurunan jumlah melanin

    The pathogenesis of the postinflammatory hypopigmentation likely varies in the varying conditions.

    For example, in tinea versicolor, the proposed pathogenesis of the postinflammatory

    hypopigmentation is a result of the inhibition of tyrosinase by dicarboxylic acids formed by

    Malasezzia furfur,[72] whereas in other disorders, loss of functional melanocytes has been

    attributed. Usually, the patients biggest concern is when and if the pigment will return.

    Unfortunately, treatment remains a challenge, and in addition to treating the underlying condition,

    reassurance and time are sometimes the best interventions. Depending on the severity of the

    hypopigmentation, repigmentation can likely take weeks to years. Cosmetic camouflage can be

    maintained until repigmentation goals are met. UV light exposure has also been reported to

    expedite repigmentation.[73] Anecdotally, the use of NB-UVB or the 308-nm excimer laser may be

    useful in hastening repigmentation

    Patogenesis hipopigmentasi postinflammatory mungkin bervariasi dalam berbagai kondisi. Misalnya,

    dalam panu , patogenesis diusulkan hipopigmentasi postinflammatory adalah hasil dari

    penghambatan tirosinase oleh asam dikarboksilat dibentuk oleh Malasezzia furfur , [ 72 ] sedangkan

    pada gangguan lain , hilangnya melanosit fungsional telah dikaitkan . Biasanya , kekhawatiran

    terbesar pasien adalah ketika dan jika pigmen akan kembali . Sayangnya , pengobatan tetap

    dapat mengambil minggu untuk bertahun-tahun. Kamuflase kosmetik dapat dipertahankan sampai

    tujuan repigmentation terpenuhi . Paparan sinar UV juga telah dilaporkan untuk mempercepat

    repigmentation . [ 73 ] Anecdotally , penggunaan NB - UVB atau 308 nm excimer laser yang mungkin
