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.
- MED-calibrated starting dose
- Automatic compensation as lamp output drops
- Condition-specific dosing protocol
- PASI (Psoriasis Area and Severity 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
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.
