Vitiligo & UVThera
Vitiligo causes patchy loss of skin colour. NB-UVB phototherapy is the most evidence-backed way to bring pigment back.
Understanding vitiligo
What's happening, and why UV therapy helps.
What is it?
Vitiligo happens when melanocytes — the cells that produce skin pigment — stop working or are destroyed, usually by the body's own immune system. This leaves smooth, well-defined white patches, most often on the face, hands, and skin folds. It isn't contagious and doesn't cause physical harm, but the visible patches can have a significant impact on confidence and social wellbeing.
Why NB-UVB phototherapy works
311nm narrow-band UVB stimulates the melanocytes that remain at the edges of a patch and inside hair follicles, encouraging them to migrate, multiply, and repigment the affected skin. This is why phototherapy is considered first-line treatment for progressive vitiligo, particularly when patches are widespread or in early stages.

How UVThera helps with vitiligo
Device, app, and dashboard — working together.
UVThera isn't just a UV lamp. It's a closed loop between what your skin actually receives, what you track, and what your dermatologist sees.
- MED-calibrated starting dose
- Automatic compensation as lamp output drops
- Condition-specific dosing protocol
- VASI (Vitiligo Area Scoring Index) auto-scoring
- Session photo timeline
- Reminders so you don't miss a dose
- Live compliance & adherence tracking
- Remote protocol adjustments
- ABHA-linked treatment record
Outcome tracking
VASI scoring, not guesswork.
VASI quantifies how much of the body surface is affected and how much pigment has returned, giving you and your dermatologist an objective number instead of a visual guess.
What to expect
Your treatment journey.
Every protocol is set by your dermatologist, but here's a typical journey for vitiligo with consistent treatment.
Recommended devices
Which UVThera device fits vitiligo?
The Excimer Pen (308nm) is often preferred for small, stubborn patches on the hands or face, while UVThera Pro or LED suit larger body-surface treatment.
