NB UVB Light Theraby

Narrow Band Ultraviolet Light

Phototherapy is the use of ultraviolet (UV) light to slow the rapid growth of new skin cells. This is helpful in treating psoriasis, which causes skin cells to grow too rapidly. There are two types of ultraviolet (UV) light therapy. We use the narrow band UVB light therapy. Narrow band ultraviolet B (NB UVB) is used to treat various skin conditions, including psoriasis, atopic dermatitis (eczema), and itching. This treatment exposes your skin to ultraviolet (UV) light for varying lengths of time.

Possible benefits include improvement of existing lesions and reduction of new lesions. NB UVB will not lead to a permanent cure, but can effectively control or improve your condition, sometimes over extended periods of time. Each patient will vary in the number of treatments required per week and the time it will take to reach significant improvement or clearance. Most patients initially require 3 treatments per week.

Typically, treatments start with only 30 - 60 seconds of UV light exposure. You are exposed to the light until it causes the skin to turn slightly pink. When the skin no longer turns pink in the 24 hours after a treatment, the exposure time is increased. It may take 15 to 25 treatments or longer to improve your condition. Not all patients will respond quickly or clear completely. However, in many cases, NB UVB has resulted in near-total clearing or remission.
