UV Therapy

Ultraviolet B (UVB) phototherapy is a treatment modality that utilizes shortwave ultraviolet radiation to manage various skin conditions, particularly psoriasis. This therapeutic approach works primarily by suppressing DNA synthesis within skin cells, leading to a reduction in cellular proliferation and inflammation, which are key contributors to the symptoms of psoriasis and similar disorders.

Among the different types of UVB phototherapy, narrowband UVB (NB-UVB) therapy, which operates at wavelengths between 311 and 312 nanometers, has gained popularity over traditional broadband UVB phototherapy (270–350 nm). One of the main advantages of narrowband UVB therapy is its ability to deliver more targeted treatment, which requires shorter exposure times. Patients often experience quicker sessions, making it more convenient and manageable.

Additionally, studies have shown that narrowband UVB phototherapy not only shortens treatment duration but also extends the periods of remission for patients. This means that individuals undergoing NB-UVB therapy may experience fewer flare-ups and a better quality of life compared to those treated with broadband UVB. The increased efficacy and reduced side effects associated with narrowband UVB make it a preferred choice for clinicians and patients alike in the ongoing management of psoriasis and other photodermatoses.
