Does a dermatology perform narrowband UVB phototherapy?

Narrowband UVB uses a controlled band of ultraviolet light directed at affected skin. It may be considered for conditions such as psoriasis, eczema, vitiligo, or other disorders when the dermatologist believes supervised light exposure could help. Treatment is delivered in a clinic booth or with a targeted device, with the exposure adjusted to your skin response. Improvement usually requires a planned series of appointments rather than a single session. Temporary redness, dryness, or itching can occur.

Tell the dermatologist about medicines that increase light sensitivity, previous light reactions, eye conditions, and any history of skin cancer. Follow instructions about which creams, cosmetics, and areas to cover. Attend sessions consistently and never increase exposure at home to make up for a missed visit. Report redness that lasts, blistering, unusual pain, or a new rash before the next session so the dose can be reviewed.

Contact the treatment team if treated skin becomes intensely red, blistered, swollen, or painful, or if an eye becomes painful or sensitive to light. Seek urgent help for facial swelling, breathing difficulty, faintness, or widespread blistering. A rapidly changing pigmented spot should be assessed separately and should not be assumed to be a treatment reaction.

Ask why narrowband UVB is being considered, which areas will be treated, how your starting exposure is chosen, how often reviews occur, and what symptoms mean the dose should change. Ask about eye protection, medicines to avoid, home sun exposure, and what happens if your skin condition worsens between sessions.
