The NB-UVB machine is a vital tool for vitiligo treatment. Using narrowband ultraviolet B (NB-UVB) light, this device exposes the affected skin areas to controlled doses of UVB radiation.

The targeted light stimulates repigmentation by activating melanocytes and improving melanin production. 

NB-UVB therapy for vitiligo is considered safe and highly effective, offering visible results in pigmentation restoration. 

With regular sessions, patients can experience significant improvement in their skin condition, enhancing their confidence and quality of life. The NB-UVB machine has revolutionized vitiligo treatment, providing a non-invasive and promising solution.
