Vitiligo & UVThera
Vitiligo causes patchy loss of skin colour. UVB phototherapy, with 311 nm narrowband for larger areas and targeted 308 nm for smaller patches, 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.
Narrowband UVB (311 nm)
Treats larger areas of skin at once. UVB calms the immune attack on pigment cells and stimulates the remaining melanocytes to repigment the patches. It's the first-line treatment for widespread or spreading vitiligo.
Targeted 308 nm therapy
Focuses UVB light on individual patches, so only the affected skin is treated. Well suited to small or stubborn areas such as the face, hands and feet, and to stable vitiligo that hasn't responded fully to other treatment.
THE NUMBERS
What the evidence says.
3 in 4
patients see at least 25% repigmentation within 6 months of narrowband UVB
2×
as many patients reach 75%+ repigmentation at 12 months as at 6 months, so consistency matters

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.
COMMON QUESTIONS
Vitiligo & UVThera — FAQ
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.
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.
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.
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.
