Do topical calcineurin inhibitors treat vitiligo?

Vitiligo causes areas of skin to lose pigment when pigment-producing cells are affected. A topical calcineurin inhibitor changes local immune signalling and may support repigmentation in some patches. Dermatologists may consider it for places such as the face or skin folds, where prolonged corticosteroid use may need particular caution.

The response can be gradual and may differ between body sites. Hair-bearing skin may respond differently from areas where pigment cells are absent or severely depleted. A cream does not stop every new patch, and existing white areas may need a broader plan that can include light-based treatment, camouflage or sun protection.

Have the diagnosis confirmed before treating a pale patch, since pigment loss has several possible causes. If prescribed, apply the medicine exactly as directed and keep it away from the eyes and inside of the mouth. Use broad-spectrum sun protection and avoid deliberate tanning, because depigmented skin burns more easily and contrast can become more noticeable.

Mark the starting areas with photographs in consistent lighting. At follow-up, discuss new patches, colour returning around hair follicles, irritation and whether another treatment should be added.

Contact a clinician if treated skin develops marked burning, swelling, crusting or signs of infection. Arrange a dermatology review for rapidly spreading pigment loss, involvement of the eyelids or lips, or major emotional distress. Urgent care is appropriate for severe eye pain, facial swelling or breathing difficulty after applying any product.

Is this definitely vitiligo, and which sites are suitable for a topical calcineurin inhibitor? What improvement should I look for, and when should progress be reviewed? Should I combine it with light treatment or another option? How should I protect and monitor depigmented skin?
