NB-UVB (Narrowband UVB) phototherapy is a medical treatment that uses a specific wavelength of ultraviolet B light to treat various skin conditions, particularly those related to excessive cell growth, such as psoriasis, vitiligo, and eczema. UVB light, in general, slows down the excessive growth of skin cells and reduces inflammation.
XTRAC is a brand name for a specific type of NB-UVB phototherapy device. The XTRAC laser delivers a highly targeted beam of UVB light to affected areas of the skin, minimizing exposure to healthy skin. It’s often used for treating localized areas of psoriasis, vitiligo, and other skin conditions. This targeted approach can result in more effective treatment with fewer side effects compared to broader UVB treatments.
