Previously, many different wavelengths of light (broad band) in the ultraviolet B spectrum were given to treat skin diseases. However, it was found that giving only very limited narrowband wavelengths of light was just as or more effective as broadband. It also offers a better side effect profile in the form of less burning, skin damage, and possibly skin cancer. Narrowband UVB is the administration of light to treat various skin diseases including psoriasis, eczema, and vitiligo.
