NB-UVB Phototherapy Cabin: A Patient Guide

An NB-UVB phototherapy cabin exposes selected skin to a narrow band of ultraviolet B light during supervised dermatology treatment.

It is a standing booth fitted with light sources around the patient. The cabin allows broad areas of skin to receive a planned dose in one session. It is different from a tanning unit: its use, dose, and treatment schedule are set by a dermatology team.

Before treatment, staff review changes in your skin, medicines, and recent sun exposure. They explain which areas should be exposed or covered. You may be asked to remove products that could affect how your skin reacts to light.

You stand in the cabin wearing the protective items specified by the clinic, including eye protection. The session is timed, and staff adjust future exposure based on your skin response and the prescribed plan. Consistency with appointments can matter because light treatment is usually delivered as a course rather than a single visit.

The cabin supplies light; it does not establish a skin diagnosis or replace examination of a changing lesion. It may not suit every skin condition, every body area, or every medical history. Treatment can be deferred or changed when the skin is already irritated or when medicines increase sensitivity to ultraviolet light.

A cabin session is not home sun exposure, and more exposure is not a substitute for the prescribed schedule. Tell the team if your symptoms change between visits so they can decide whether the plan still fits.

Depending on the condition and the areas involved, a dermatologist may discuss topical treatment, medicines taken by mouth or injection, targeted light devices, or a different phototherapy approach. The choice reflects the diagnosis, the extent of affected skin, practical attendance needs, and prior treatment response.

Bring an up-to-date medicine list and report any reaction after a session before your next one. Wear the clinic-provided protection exactly as instructed, and ask which moisturisers, topical medicines, or cosmetics should be used before and after treatment. Keep your own record of new redness, itching, or tenderness.

Eye protection and the prescribed coverage of sensitive areas are essential parts of a cabin session. Mild redness or itch can occur after ultraviolet exposure. Contact the clinic promptly if you develop pronounced redness, blistering, significant pain, an unexpected rash, or any reaction that feels severe.
