NB-UVB Phototherapy Is a Well-Studied Treatment for Psoriasis
Psoriasis is an autoimmune condition that speeds up skin-cell turnover. NB-UVB phototherapy has been studied for decades as a way to slow that process and calm the underlying inflammation.
Clinical Guidelines

A 2024 randomized clinical trial published in JAMA Dermatology — a collaboration between the National Psoriasis Foundation, University of Pennsylvania, and University of Utah — found home-based NB-UVB phototherapy non-inferior to office-based treatment, with strong safety and higher patient adherence.

How NB-UVB Light Supports Skin & Immune Health
NB-UVB is tuned to a specific wavelength that triggers a natural, well-studied response in the skin’s immune cells.
Targeted Wavelength
Narrowband UVB delivers a precise dose of light shown to calm overactive immune cells in the skin, without the broader risks of older broadband UV treatments.
Immune Modulation
NB-UVB helps expand regulatory T-cells, which is associated with reduced inflammation and improved outcomes for psoriasis.
Lasting Remission
Many patients who clear with NB-UVB stay in remission for up to 18 months without needing ongoing medication or continued phototherapy.

Smaller at-home therapy lights outperform going to the clinic because you use them more often. The Cytokind team provides ongoing support – we are with you all the way.
