Psoriasis & UVThera

Psoriasis is a chronic inflammatory condition that speeds up skin cell turnover. NB-UVB calms the inflammation driving it.

Understanding psoriasis

What's happening, and why UV therapy helps.

What is it?

Psoriasis is an immune-driven condition where skin cells are produced much faster than normal, building up into thick, scaly, often itchy plaques — commonly on the scalp, elbows, knees, and lower back. It's a chronic condition that tends to flare and settle over time, and is not contagious.

Why NB-UVB phototherapy works

NB-UVB phototherapy suppresses the overactive immune signals (particularly T-cells) that drive psoriasis plaque formation, while also slowing down the excessive skin cell turnover. It's recommended as first-line treatment for moderate-to-severe plaque psoriasis by major dermatology guidelines, including for patients who haven't responded well to topical treatments alone.

How UVThera helps with psoriasis

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 psoriasis 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 PASI score updates as you progress.
  • PASI (Psoriasis Area and Severity 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 PASI 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

PASI scoring, not guesswork.

PASI combines plaque area, redness, thickness, and scaling into a single severity score, so you can track real clearance instead of relying on how a plaque "looks" at a glance.

What to expect

Your treatment journey.

Every protocol is set by your dermatologist, but here's a typical journey for psoriasis with consistent treatment.

1
Week 1–2
MED calibration
Your UVThera device calibrates your starting dose based on your skin's individual UV sensitivity.
2
Week 4–6
Early improvement
Most patients notice reduced redness and scaling within the first month of consistent sessions.
3
Week 8–12
Significant clearance
PASI scores typically show meaningful improvement with 3 sessions/week sustained over 2–3 months.
4
Ongoing
Flare management
Your dermatologist can adjust dose or frequency the moment a flare shows up on your dashboard.

Common questions

Psoriasis & UVThera — FAQ

How is psoriasis different from eczema? +
Psoriasis plaques are typically thicker, well-defined, and silvery-scaled, driven by immune-triggered skin cell overproduction. Eczema tends to be itchier with less-defined, often weepy patches driven more by skin barrier and allergic-type inflammation.
How often do I need sessions? +
Most protocols start at 3 sessions per week. Your dermatologist sets the exact frequency and escalation schedule from the dashboard based on your skin's response.
Can phototherapy treat scalp psoriasis? +
Yes — the Excimer Pen's targeted aperture is well-suited for scalp plaques where a full-body device would be impractical.
What happens during a flare? +
Report changes through the app, or your dermatologist may spot it from your photo timeline. They can pause escalation or adjust your protocol remotely.
