Psoriasis: understand where phototherapy fits.

This hub is narrow on purpose: it covers the phototherapy decision and hands broader psoriasis treatment depth to specialist resources.

What the published evidence establishes

A narrow starting point, not a personal forecast.

Narrowband UVB is used for skin conditions including vitiligo and psoriasis. [1] [2] That does not establish whether it is appropriate for you or how your skin will respond.

    What this source does and does not support

    Supports that therapeutic narrowband UVB lamps have an emission spectrum peaking near 311–313 nm, and that this narrow band was selected because it is the most effective part of the UVB spectrum for treating psoriasis. It is a clinical guideline for clinicians administering phototherapy; it does not establish any home-use dose, and this site never reproduces its dosing schedules.

    What this source does and does not support

    Supports, in plain patient-facing language, that narrowband UVB uses a small part of the UVB spectrum and is used for skin conditions including psoriasis, eczema and vitiligo. As patient-education material it is context, not primary evidence, for any efficacy claim. Its review date is June 2025, so re-verify before relying on it past then.

About the SteadySkin app

The app currently supports vitiligo only.

Psoriasis support is planned, without a promised date. This website remains usable without the app, and this page does not send you to a vitiligo-only download.
