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.

The Device
💡
Real dosimetry, every session
A calibrated photodiode measures the actual UV dose reaching your skin — not just elapsed time — so your vitiligo protocol stays accurate even as the lamp ages.
  • MED-calibrated starting dose
  • Automatic compensation as lamp output drops
  • Condition-specific dosing protocol
The App
📱
Tracks what matters, automatically
Every session, dose, and photo is logged without you having to remember anything — and your VASI score updates as you progress.
  • VASI (Vitiligo Area Scoring Index) auto-scoring
  • Session photo timeline
  • Reminders so you don't miss a dose
The Dashboard
🩺
Your dermatologist sees it too
Compliance, dose history, and your VASI trend are visible to your prescribing dermatologist in real time — no waiting for your next visit to adjust your plan.
  • 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.

1
Week 1–2
MED calibration
Your UVThera device runs a Minimal Erythema Dose test to find your safe starting dose.
2
Week 6–12
Early repigmentation
Most responsive patients start seeing fine pigment specks at the edges of patches.
3
Month 3–6
Visible improvement
Significant repigmentation typically becomes visible with consistent 3–5 sessions/week.
4
Ongoing
Maintenance & monitoring
Your dermatologist adjusts the protocol based on VASI trends from your dashboard.

Common questions

Vitiligo & UVThera — FAQ

How long until I see results? +
Most patients on a consistent 3–5 sessions/week schedule see initial repigmentation specks at 6–12 weeks. Significant, visible repigmentation typically takes 3–6 months.
Will the new skin colour match exactly? +
Repigmentation usually starts as small specks that gradually merge. Colour match improves over time but can vary by skin area — your dermatologist will track this using VASI scoring.
Does vitiligo come back after treatment? +
Vitiligo is a chronic autoimmune condition, so ongoing maintenance sessions are often needed even after repigmentation. Your dashboard helps your dermatologist plan a sustainable long-term schedule.
Can I treat just my hands or face? +
Yes — the Excimer Pen is designed for targeted, small-area treatment like hands, feet, and face, with the same real dosimetry as the full-body devices.
