Narrowband UVB phototherapy helps to slow down the abnormal growth of skin cells in psoriasis,
reduces inflammation, and stimulates repigmentation in vitiligo. It is often
used when topical treatments are ineffective or impractical, and it may also be
used in combination with other therapies.
Benefits of Narrowband UVB is that it emits a specific wavelength of ultraviolet light that
is narrower compared to traditional UVB therapy. This specificity reduces the
risk of potential side effects such as burning and premature aging of the skin.
It also can be targeted to specific areas of the body affected by skin
conditions, allowing for more precise treatment and minimizing exposure to
unaffected areas.
Treatment sessions are typically short, starting with a few seconds to a few minutes, and
gradually increasing in duration as the patient’s skin becomes accustomed to
the UVB light. The frequency and duration of sessions depend on the condition
being treated, the patient’s skin type, and other factors determined by the
healthcare provider.
