Narrowband UVB (NB-UVB) phototherapy is a medical light treatment that exposes the skin to a specific wavelength of ultraviolet light (311–313 nm). This wavelength is commonly used in dermatology because it can influence immune activity in the skin while minimizing unnecessary ultraviolet exposure.
In clinical practice, NB-UVB phototherapy may be used as part of the management plan for a variety of inflammatory and immune-mediated skin conditions.
NB-UVB phototherapy may be considered for individuals experiencing:
Treatment is always determined based on clinical assessment, skin type, and response to therapy.
NB-UVB light interacts with cells in the skin and may influence:
Because the treatment is delivered at a precise wavelength, it allows controlled exposure that can be adjusted based on skin sensitivity.
Phototherapy is typically delivered as a series of treatments over time, as the skin responds gradually to light exposure.
A general treatment program may include:
Many treatment programs involve multiple sessions per week during the early stages, followed by spacing treatments further apart once improvement is observed.
Treatment schedules vary depending on the condition being addressed and individual response.
NB-UVB phototherapy treatments are carefully monitored to ensure safe dosing and minimize irritation. Exposure times are adjusted based on skin response and any changes in symptoms.
Patients are provided with guidance on skin care, sun exposure considerations, and how to monitor for any skin reactions between sessions.
