How is narrowband UVB phototherapy different in children?

Narrowband UVB exposes affected skin to a controlled band of ultraviolet light to calm some inflammatory skin conditions and support repigmentation in selected cases. A child’s treatment plan is adjusted for skin type, diagnosis, treatment response, and ability to stand safely in the cabinet or use a hand-held device. The team must make sure the child understands the routine and keeps protective eyewear in place. The skin may become pink, warm, dry, or irritated after treatment; a stronger reaction should be reported.

Follow the clinic’s instructions about creams, medicines, and washing before each session, and tell the team about any new products or sun exposure. An adult should stay involved, help with positioning and eye protection, and record any redness or soreness between visits. Never add extra home or sun exposure to make treatment work faster. Keep appointments consistent where possible, because the clinician uses the response to adjust the next dose. Read the treatment overview for [Narrowband UVB Phototherapy](/treatments/medical-dermatology/narrowband-uvb-phototherapy/).

Contact the treatment team if redness lasts unusually long, becomes painful, blisters, peels extensively, or interferes with sleep or daily activity. Report eye pain, light sensitivity, or a child who cannot keep protective eyewear on. Pause further sessions until the clinic advises what to do if there has been a significant reaction or a new medicine that may increase light sensitivity.

Ask why NB-UVB is being recommended, how the dose will be adjusted for your child, what protective equipment is needed, and which reactions require a call. Clarify how an adult should support the child during each appointment.
