Vitiligo on Black skin

Key cue: Chalk-white patches with sharp borders, usually symmetric. Contrast against Black skin is high; psychosocial impact is significant. Treatment works — early dermatology referral matters.

Vitiligo is an autoimmune depigmenting skin disease affecting about 1% of the global population. While the prevalence is similar across racial groups, the visibility and psychosocial impact on Black skin are vastly higher — contrast between depigmented patches and pigmented surrounding skin is much greater, and vitiligo in Black communities is associated with significant stigma and mental-health burden.

What it actually looks like

Textbook says

Textbook: well-demarcated milk-white (depigmented) macules and patches, most commonly in periorificial areas (around eyes, mouth), dorsa of hands, axillae, groin, and over joints. Typically symmetrical (non-segmental vitiligo); segmental form follows a dermatomal distribution and is usually unilateral.

On Black skin

On Black skin the diagnostic features are actually more obvious, but several points deserve attention:

Depigmentation is dramatic — a chalk-white or milk-white patch against Black skin. A Wood's lamp examination (long-wave UV) highlights depigmentation and helps distinguish vitiligo from post-inflammatory hypopigmentation.
Trichrome vitiligo — a transition zone of intermediate pigment between the depigmented centre and normal skin — is seen more commonly on Black skin and is highly specific.
Koebner phenomenon — new vitiligo lesions at sites of skin trauma (scratches, friction, surgical incisions) — is common; protect the skin.
Associated autoimmune conditions (thyroid disease, type 1 diabetes, Addison's disease, pernicious anaemia) are more common — ask for TSH and fasting glucose screening.
Effective therapies: topical corticosteroids, topical calcineurin inhibitors (tacrolimus, pimecrolimus — preferred for face), narrowband UVB phototherapy, excimer laser, and — since 2022 — topical ruxolitinib (FDA-approved). Combination therapy works best. Early treatment is more effective.
Psychosocial support is critical. Vitiligo on Black skin carries significant stigma in many communities; connect with Global Vitiligo Foundation resources and peer support.

What to look for

Milk-white patches, typically symmetric, on the face, hands, feet, or around body orifices.
Spreading or new patches.
Patches at sites of injury or friction.
Hair turning white in a patch on the scalp, eyebrows, or lashes (leukotrichia) — a sign the follicle melanocytes are affected and treatment response may be slower.

When to seek care

Schedule a dermatology referral within a few weeks. Early treatment (within the first 1-2 years of onset) has the best repigmentation response. Ask for Wood's lamp examination, TSH, and fasting glucose.

Common misdiagnosis

On Black skin, vitiligo is sometimes confused with: post-inflammatory hypopigmentation (usually has history of inflammation and the patches have indistinct edges); pityriasis alba (usually on children's faces, mild scale, less sharp edges); tinea versicolor (positive KOH prep, fine scale); hypopigmented sarcoidosis (patches can feel firm on palpation); leprosy (very rare in the US; patches have decreased sensation).
