UV phototherapy uses specific wavelengths of ultraviolet light to treat chronic skin conditions like vitiligo, psoriasis, and eczema. At the cellular level, UV light suppresses the overactive immune response that drives these conditions, stimulates melanocyte activity in vitiligo, and slows the abnormal skin cell turnover seen in psoriasis. It is not a new treatment — it has been a first-line clinical therapy in dermatology for over 30 years, backed by an extensive evidence base.

UVThera devices are clinically indicated for vitiligo, psoriasis, eczema, and atopic dermatitis. These are the four conditions with the strongest evidence base for UV phototherapy as a first-line or second-line treatment. If you have a condition not on this list, we recommend consulting your dermatologist — phototherapy has broader applications, but these four are the ones UVThera devices are specifically designed and validated for.

This depends on your condition and the location of your lesions. For vitiligo, most patients see the first signs of repigmentation — small pigmented dots appearing within the white patch — at 6 to 12 weeks of consistent treatment. Significant cosmetic improvement typically takes 3 to 6 months. Psoriasis usually responds faster, with many patients seeing meaningful clearance within 4 to 6 weeks. Eczema varies widely depending on severity, but symptom relief often begins earlier than visible skin change. The honest answer is: phototherapy is not a quick fix. It is a sustained treatment that rewards consistency over time.

The standard protocol for most conditions is 3 to 5 sessions per week. Your dermatologist will prescribe the specific frequency based on your condition, skin type, and the location of your lesions. Fewer sessions per week slow down the therapeutic effect; more than 5 sessions per week does not meaningfully accelerate it and increases the risk of overexposure. Consistency within your prescribed schedule matters more than the exact number.

Phototherapy induces repigmentation in vitiligo and clearance in psoriasis, but it does not cure the underlying autoimmune condition. Some patients achieve long periods of remission after completing a course of treatment. Others require maintenance therapy to sustain their results. Your dermatologist will advise you on a maintenance schedule based on how you responded to treatment. The goal of a full course of phototherapy is durable improvement — not a one-time fix, but not a lifelong dependency either.

Yes, with appropriate clinical supervision. NB-UVB phototherapy is considered safe for paediatric use and is used in children with vitiligo and atopic dermatitis when topical therapies have not provided adequate control. The starting dose and escalation protocol for children are adjusted for age and skin sensitivity. UVThera recommends that phototherapy in children always be initiated and supervised by a paediatric dermatologist.

UVThera devices use 308nm excimer light and 311nm NB-UVB, depending on the specific device. Both wavelengths are clinically validated for vitiligo, psoriasis, and eczema. 308nm excimer is optimised for targeted spot treatment and shows faster initial repigmentation in localised patches. 311nm NB-UVB has a broader treatment area and decades of evidence for full-course home phototherapy. Your dermatologist will recommend the appropriate wavelength based on the extent and location of your condition.

UVThera LED-based devices are rated for up to 10,000 hours of use. For lamp-based devices, UVThera Pro tracks lamp hours automatically and alerts you when replacement is approaching — typically at around 1,000 hours of use. You can order replacement lamps directly through the app. UVThera Basic recommends lamp replacement at 12 to 18 months of regular use. Because UVThera Pro compensates for lamp degradation through dosimetry, you will continue to receive the correct therapeutic dose even as the lamp ages — but replacement is still recommended at the advised interval to maintain optimal session efficiency.

Yes, by design. Once your dermatologist sets your protocol in the dashboard, the device manages the clinical complexity — dose calculation, session timing, escalation schedule, and lamp compensation. As a patient, you position the device over the treatment area and start the session. The app guides you through each step, prompts you to photograph your treatment site, and handles the rest. You do not need to calculate doses or manage escalation yourself.

UVThera devices include UV-blocking quartz windows that prevent unintended exposure outside the treatment area, automatic dose cutoffs that prevent overexposure if the device is held in one position for too long, session logs that track every treatment and flag anomalies, and protocol enforcement that prevents patients from exceeding the dose ceiling set by their dermatologist. The app also includes eye protection guidelines in the instructions for use and prompts you to use protective eyewear when treating near the face.

The UVThera app connects to your device via Bluetooth and manages your entire treatment experience. It schedules sessions and sends reminders based on your prescribed frequency. It prompts a photograph of your treatment site at each session and builds a visual timeline of your repigmentation progress over time. It logs every session — date, duration, dose delivered — and syncs this to your dermatologist's dashboard. It tracks cumulative dose and lamp hours, and alerts you when a lamp replacement is approaching. It also integrates with your ABHA health ID, so your complete phototherapy record travels with you regardless of where you seek care.

Yes. This is one of the core features of the UVThera connected platform. Your dermatologist has access to a clinic dashboard that shows all their UVThera patients' session logs, cumulative dose history, and repigmentation photo timelines. They can review your progress, adjust your protocol, and flag concerns — all without requiring you to attend a clinic appointment. If you miss sessions, this is also visible in the dashboard, allowing your dermatologist to reach out proactively rather than discovering the gap at your next review.

ABHA — Ayushman Bharat Health Account — is India's national digital health ID. UVThera links your session records to your ABHA ID, meaning your complete phototherapy history is stored as part of your permanent health record. If you move cities, change your dermatologist, or need to be seen at a different facility, your new doctor can access your full treatment history — MED value, cumulative dose, session log, repigmentation timeline — without starting from scratch. For a treatment like vitiligo phototherapy that runs over many months, this continuity is genuinely clinically important.

Your session history and ABHA-linked records remain accessible through your ABHA health ID. The UVThera app retains your treatment timeline and photo history within the app for as long as you have an account. We do not delete treatment records if you stop active use of the device.

The UVThera app is currently in final development and will be available soon. You can join the waitlist on the UVThera website to be notified at launch and to receive early access. Dermatologists who register now will receive priority access to the clinic dashboard and the demo device programme when the platform goes live.

The dashboard is a browser-based interface accessible from any device. Once a patient is onboarded with a UVThera device, their session data syncs automatically to the dashboard after each treatment. You can view individual patient records — session logs, dose history, repigmentation photos — or a summary view across your full patient list. You can set and adjust protocols remotely, including starting dose, escalation schedule, maximum dose cap, and session frequency. Patients who miss sessions are flagged automatically, giving you the opportunity to intervene early rather than at the next scheduled appointment.

Yes — this is precisely what the platform is designed for. Prescribing UVThera for home use does not mean handing control to the patient. Your protocol is set in the dashboard and enforced by the device. You retain full visibility into every session, every dose, and the patient's photographic progress. Home use extends your clinical reach without reducing your oversight. Many dermatologists find they have more real-world data on their home phototherapy patients than on their clinic-based ones.

UVThera's wavelengths — 308nm excimer and 311nm NB-UVB — have an extensive peer-reviewed evidence base spanning over 30 years. The dosimetry approach is supported by clinical studies demonstrating that consistent, measured UV delivery produces superior outcomes compared to timer-based protocols, particularly over long treatment courses where lamp degradation becomes significant.

Yes. Registered dermatologists can access a clinic demonstration unit at nominal cost through UVThera's demo programme. This allows you to assess the device, experience the dashboard, and evaluate the platform before prescribing it to patients. To register, contact UVThera through the dermatologist enquiry form on the website.
